The large simplified sizing example is for deployments of up to 20,000 users or devices and includes calling, IM and presence, voice messaging, edge services, and meeting workloads. Total user BHCA in this example is [(300 users) (5 BHCA per user)], which is 1,500 total user BHCA. These extra call flows add to the sizing load of Unified CM as follows: Collaborative conferencing system can be cloud based, on-premises based, or hybrid. lastFormURL : document.location.href We may need to repeat these steps a number of times because other factors (such as software release, call mix, and types of endpoints) can impact resource usage. However, because not all VM configurations are supported on all server platforms, mixing VM configurations will impact the overall cluster capacity. With Webex we know this is going to be the best Mother's Day show ever.. Using the UDS contact source to resolve contacts puts additional load on the system. Contact centers demonstrate a unique pattern of traffic, because these systems typically handle large volumes of calls that are handled by a small number of agents or interactive voice response (IVR) systems. The following IM and Presence deployment types and features will require 15k-user OVA or higher OVA template: Failure to provide additional resources by using a larger OVA template for IM and Presence deployment types and features above will result in higher system CPU, IM and Presence service core dumps, persistent chat and other performance related issues. The following notes apply to Table 1-10 : Note To calculate the capacities of each of the media functions on the DSPs supported by each individual ISR, refer to the Cisco ISR product data sheets. New Unified CM OVA templates and increased capacity numbers. Up to 500 EM logins/logouts per minute supported. Although the large Unified CM VM configurations are able to support CTI for all of their registered devices, the smaller VM configurations do not scale that high. Jacksonville, Florida. Construido para permitir conexiones humanas a nivel mundial. All other registered devices such as media termination points (hardware of software) or SIP trunks do not count against these limits. For example, when a television advertisement runs for a particular holiday package with a 1-800 number, the call arrival rate for the system will experience a peak of traffic for about 15 minutes after the ad airs. Calls can originate and terminate within the same server, or they can originate and terminate on two different servers or clusters. Specialized equipment is required to provide the switching or combining of video streams. North Miami, FL 33161 (866) 573-5300. Desde que implement CxEngage by Serenova en 2019, Virgin Pulse ha estado utilizando su solucin de centro de contacto omnicanal para expandir su equipo y aumentar su eficiencia en todos los canales al aprovechar los informes avanzados de CxEngage y traer su propia telefona (BYOT). In the case of multicast MoH, each multicast-enabled audio source generates one MoH steam for each MoH codec enabled. Government Devices are designed for: Conference rooms with large screens and digital whiteboards Up to 1,000 CTI ports and 200 CTI route points. Our video conferencing solutions allow you to upgrade your conference room to support video calls from Microsoft Teams , Zoom , Cisco Webex , Google Meet, and more. Conferencing traffic has considerably different characteristics than point-to-point voice/video calls. Instead, Cisco Meeting Server and Cisco IOS-based MTP are included. Vyopta Incorporated. Cisco WebDialer provides a convenient way for users to initiate a call. The formal definitions of the VM configurations for Unified CM and other Unified Communications products are available at the following location: https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/collaboration-virtualization-sizing.html. For accurate sizing of call traffic, you must consider the following factors: Each different type of call takes a different amount of CPU resources to set up. You need to account for these users when sizing the number of concurrent participants for these services. Cisco Meeting Management (CMM) nodes are deployed on the Large OVA/VM. Products may specify the size and duration of traffic bursts that they can handle. Refer to the documentation at https://www.cisco.com/go/virtualized-collaboration for more information. However, most participants join their conference call within a few minutes of the meeting start time, and most conference calls are scheduled to start at the beginning of the hour. Note Enabling EM Security does not diminish performance. Note OVA size refers to the total number of devices and does not reflect the impact the above features have on IM and Presence. The slope of the linear section of the graph defines the resource usage and/or cost for each incremental addition of work. Assuming a system of 300 users at 5 BHCA each, with each user having one remote destination or mobility identity (total of 300 remote destinations and mobility identities), the calculation for the total remote destination and mobility identity BHCA would be: Total remote destination and mobility identity BHCA = 0.5 (300 users) (1 remote destination or mobility identity per user) (5 BHCA per user) = 750 BHCA. PSTN gateways handle traffic between the Unified Communications system and the PSTN. 2.Capacity for the small OVA is dependent on hardware. To accurately size a conferencing deployment, it is important to quantify and understand things like the maximum number of concurrent users, the maximum number of concurrent conferences, and the maximum number of participants in a single conference supported by the system. Get your business, organization, group or team connected securely with a full-featured Webex trial. If required, additional data points (at intermediate load levels) are obtained in order to define the actual system behavior. CPU usage can vary considerably depending on the type of calls. They are stored in the. If you have a large number of clients operating in deskphone control mode, make sure that you evenly distribute those CTI connections across all Unified CM subscribers running the CTIManager service. When configured in deskphone control mode, the client establishes a CTI connection to Unified CM upon login and registration to allow for control of the IP phone. Other factors that affect sizing for voice messaging are: Table 1-16 shows the applicability of the various voice messaging solutions to the scalability requirements of the deployment. Vyopta Incorporated. Record your meeting to get post-meeting transcript and presentation content. For example, the UDS service can be used by Jabber clients to search for contacts in the Unified CM User database. In addition to native applications provided by Unified CM, third-party applications may also be deployed that use Unified CM CTI resources. If the peak is underestimated, the system could experience service degradation or equipment outages when the actual peak traffic is encountered. mktoForm.addHiddenFields({ You can define groups of devices (phone devices or trunk devices) with usage characteristics based on BHCA, and then you can add the BHCA for each device group to get the total BHCA for the system, always ensuring that you are within the supported maximum of 5,000 BHCA. Work the way you want to work. In general, usage of media resources can be considered to add to the BHCA that needs to be processed by Unified CM. Mixing different types of hardware platforms within a Unified CM cluster is also allowed. SAML SSO provides secure mechanism to use credentials and relevant information of the end user to be leveraged across multiple Unified Communications applications (such as Unified CM, Unity Connection, and Unified CM IM and Presence). When sizing conferencing servers, the following parameters should be considered in order to determine the type and number of servers/nodes: There are several methods for calculating conferencing resource requirements: If the average conferencing usage statistics (minutes per month spent on conference calls) is available, Table 1-18 can be used to roughly calculate the conferencing capacity requirements in terms of the number of ports needed. CPU usage will vary substantially depending on the actual hardware platform. Product overview. If newer higher density, higher performance hardware is used, VM density and therefore layout may change given overall platform capacity increase. QPT is available at, For more information on these tools and their access privileges, refer to the Collaboration Sizing Tool Frequently Asked Questions, available at, https://cucst.cloudapps.cisco.com/help/UC_Sizing_Tools_FAQ.pdf. Contact centers are engineered for high resource utilization, therefore their agents, trunks, and IVR systems are kept busy while they are in operation, which usually is 24 hours a day. Our video conferencing solutions allow you to upgrade your conference room to support video calls from Microsoft Teams , Zoom , Cisco Webex , Google Meet, and more. The way we see it, face-to-face communication is always better than any other method. There are also templates defined to support a maximum of 3,750 (Small OVA), and 10,000 endpoints (Medium OVA). Roswell, Georgia. In more advanced configurations, the SME may also host centralized voice messaging, mobility, and conferencing services. In a large system, dynamic memory is primarily a function of the number of concurrent calls. All rights reserved. Figure 1-6 Virtual Machine Placement for Large Simplified Sizing Example (1 of 2), Figure 1-7 Virtual Machine Placement for Large Simplified Sizing Example (1 of 2). General conferencing and port sizing guidance updates including removal of Cisco Webex Meeting Server. Cisco Expressway deployments rely on Cisco Unified CM as the component for call control, including remote endpoint registration. 3.All capacities based on non-sRTP streams. Therefore, it is necessary to properly account for the system resources needed for the anticipated usage. Cisco Prime Collaboration Assurance can manage phones and other network devices such as routers and switches. Because of all the factors and possible variations, the accurate sizing of a large system deployment is a complex undertaking. The exceptions are shared lines, hunt lists, and line groups. Sizing tool output provides application sizing and bill of materials for included components. For a larger number of annunciators or concurrent MoH sessions, deploy standalone Unified CM subscribers as MoH servers. The BHCA consideration becomes significant when the usage for any phone is above 4 BHCA. Resource requirements can be derived from the system load requirements by using the appropriate Erlang model. Webex Service; Third-party H.323 gatekeepers and standards-based SIP proxies; In case of a hybrid deployment, Webex Edge for Devices allows for linking your on-premises Cisco devices to the Webex Cloud and benefits from specific cloud features such as device management, monitoring, and analytics via Control Hub. The current maximum login rate for software client users is 2.7 logins per second (about 166 logins per minute) or 10,000 logins within one hour. The Erlang is a measure of traffic load on a system. Table 1-5 Maximum Number of Mobility Users and Remote Destinations and Mobility Identities per Cluster. There are no hard limits enforced by Unified CM for any of the dial plan elements, but there is a fixed amount of shared system memory available. This is a specialized tool that focuses on the specific functions of a Unified CM Session Management Edition deployment. This is assuming that all users and devices are evenly distributed across all nodes and that the software client is in softphone mode. 6.Cisco Expressway-C and Expressway-E can be clustered across multiple Business Edition 6000 nodes for redundancy purposes; however, there is no increased capacity when clustering with Business Edition 6000. As with all other applications, sizing for Cisco IM and Presence is accomplished in the following way: For IM and Presence, the following system variables in the system under analysis are relevant and must be considered for accurate sizing: Clients employed by users to obtain presence services, Operating mode for users (instant messaging only or full Unified Communications facilities). A number of factors affect Unified CM performance and must be considered when sizing a Unified CM deployment. The number of new call attempts that arrive at the system in one second, plus the number of existing calls torn down during that same one second interval. If you plan to use media authentication or encryption, keep this fact in mind and make the appropriate adjustments. Muy contento con la implementacin en nuestro centro de contacto.. When sizing such a system, consider the function it performs as well as its impact to Unified CM. For the organization in this example, several click-to-call applications are made available to the users, and it is projected that 30% of all placed calls will be initiated using WebDialer. Note For the purposes of this discussion, references to Cisco software clients include Cisco Jabber as well as Cisco Webex when deployed in Calling in Webex (Unified CM) mode. Cisco Prime Collaboration includes the following products: Prime Collaboration Provisioning, Prime Collaboration Assurance, and Prime Collaboration Analytics. Note The term co-resident refers to two or more services or applications running on the same server node or virtual machine. The Cisco software client deployment must balance client registration and other communications equally across all nodes in the cluster. Example: Calculating WebDialer Calls per Second. When sizing Cisco Expressway, you typically must consider the following parameters to determine the required number of Cisco Expressway-C and Expressway-E node pairs: Expressway-C and Expressway-E clusters support a maximum of 6 nodes. Assuming 10% of busy hour users on collaboration calls, supported call per second rate need to be at least 40% higher compared to no users on collaboration calls and 4 BHCA per user. Figure 1-5 Virtual Machine Placement for Medium #2 Simplified Sizing Example. If advanced features are being used, calls made using this technology, and the percentage of these calls that need to be redirected to the PSTN because of call quality, must also be accounted for. Likewise, desktop sharing is generally not considered video for the purposes of concurrent video and sharing. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. The endpoint consumes CPU and dynamic memory based on its call rate. The number of people participating in concurrent meetings on the system at any given time. After the system reaches this number, the next user(s) that attempt to join may experience an additional few seconds wait before connecting to the meeting. Flexible payment solutions to help you achieve your objectives. Cisco delivers the power of our portfolio in a simplified, consistent, and seamless experience to help you accelerate your digital agility in a cloud-first world. With the exception of IP Phone Services for the integrated Extension Mobility and Unified CM Assistant applications, IP Phone Services must reside on a separate web server. This tool covers the following products and components: Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Management Suite, Cisco Unified Contact Center components. MktoForms2.whenReady(function(mktoForm){ Chief among these are: Note Due to the many potential complexities surrounding megacluster deployments, customers who wish to pursue such a deployment must engage their Cisco Account Team, Cisco Advanced Services, or their certified Cisco Unified Communications Partner. Specific information for Unified CM is available at the following location: https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/virtualization-cisco-unified-communications-manager.html. In case of on premise based or hybrid system, Cisco Unified CM servers (VMs) are needed in addition to conferencing servers (VMs). Identify variations of the function that need to be tested. La solucin de centro de contacto en la nube de CxEngage permite que sus agentes se conecten con sus clientes en cualquier lugar, en cualquier momento y a travs del canal que mejor se adapte a sus necesidades. Video-Enable Your Small Collaboration Spaces. Contact centers require additional resources, such as interactive voice response (IVR) ports. It is Enterprise grade provides sizing of large and complex deals including Megacluster. Each WebDialer service can support up to 4 cps, therefore one node can be configured to run the WebDialer service in this example. Each configured remote destination or mobility identity has potential BHCA implications. For example, assume there are two classes of users with the following characteristics: Also assume 10 shared lines for each group, which would add the following BHCA values: 10 shared lines in the group at 8 BHCA = 0.5108 = 40 BHCA, 10 shared lines in the group at 4 BHCA = 0.5104 = 20 BHCA. Cisco Unified IP Phone Services act, for the most part, as HTTP clients. The average holding time for self-service calls is about 30 seconds, while a call serviced by an agent may have an average holding time of 3 minutes (the same as normal business traffic), making the overall average holding time in the contact center shorter than for normal business traffic. The Unified CM MoH server supports four codecs: G.711 ulaw, G.711 mulaw, G729a, and Wideband audio. In the context of Unified CM, applications are the "extra" functions beyond simple call processing provided by Unified CM. The traffic model for conferencing traffic needs to accommodate the following differences: A traditional traffic model assumes a Poisson distribution of busy-hour call arrivals throughout the busy hour. Therefore, the following guidelines for the current functionality of Unified CM apply when software client voice or video calls are initiated: In deskphone control mode, calls from the software client use the CTI interface on Unified CM. You cannot select this option in combination with Webex Events 3,000 below. Hello, and welcome to Protocol Entertainment, your guide to the business of the gaming and media industries. 2022 Cisco and/or its affiliates. This is the maximum number of concurrent meeting connections (or participants) allowed to use video sharing on the system at the same time. One easy-to-use app to call,meet, message, andget work done. Strong encryption and protection keeps your work safe.

Instantly meet face-to-face with the most engaging, interactive video conferencing solution. Total number of DNs 10,000 with up to 500 DNs shared across average of 3 additional endpoints. After you determine the minimum number of nodes required for the specified deployment, add the desired number of additional subscriber nodes to provide redundancy. The second medium simplified sizing example is for deployments of up to 10,000 users or devices. Unified CM provides coordination for the other Unified Communications products such as PSTN gateways, Cisco Unity Connection, Cisco Unified Communications Manager IM and Presence Service, and Cisco Unified Contact Center. Generation of call detail records (CDR) and call management records (CMR) places a heavier burden on the CPU. The Session Management Edition (SME) is a Unified CM operating in a specific deployment mode. For endpoints registered on the same subscriber node, that subscriber handles both call halves for calls between these endpoints. Built to Enable Human Connections Globally. La transformacin digital est ocurriendo en la nube. There are two parameters that are key to Unified CM's capacity to support single number reach and enterprise two-stage dialing (Mobile Voice Access and Enterprise Feature Access). Cisco Webex Control Hub is a web-based, intuitive, single-pane-of-glass management portal that enables you to provision, administer, and manage Cisco Webex services. Up to 500 CTI ports and 100 CTI route points. Ofrezca una experiencia de agente consistente y compromiso con el cliente que diferenciar su marca. Itemize all of the functions that the product performs. Learn more. A given system may support less than these maximum amounts because of other applications included in the deployment. Cisco Unified IP Phone Services are applications that utilize the web client and/or server and XML capabilities of the Cisco Unified IP Phone. In some cases IM and Presence nodes may require additional resources and thus larger OVA templates to operate effectively. Designed and built from its foundation as a Software-as-a-Service (SaaS) cloud solution, Webex Contact Centers best-of-breed platform architecture brings your business the innovation, flexibility, scalability, and Shorter, effective, and secure meetings. Suite 200. According to the factor lists in Table 1-7 and Table 1-8 , the 5 lines per device renders a line factor of 1.0, while 9 applications per device renders an application factor of 1.8. Over the past year, remote work has seen accelerated adoption. These factors are described in the following sections: Solution sizing is affected by the following network design factors: A major design decision is whether to create a large centralized Cisco Unified CM cluster or to create a cluster at each major location. Note A mobility-enabled user is defined as a user that has a remote destination profile and at least one remote destination or a dual-mode device and a mobility identity configured. The following limits increase with such a deployment: However, some cluster-wide constants do not increase. The control you need to power every app in every location for a year. Using Extension Mobility (EM) impacts the system performance in the following ways: Table 1-9 shows the maximum number of EM and EMCC logins per minute for each type of VM configuration. The model can be fairly simple for some products, but it can be very complex for a product that supports multiple functions, multiple endpoint types, and multiple call types. Assuming average conferencing usage, we would assume 5-10% of users on conference calls during peak internal, thus one port for every 10-20 users. Figure 1-2 shows an example of a mix of PSTN and intracluster calls made by two users at a 6 BHCA rate. The end user's password is never stored in the Unified CM database when enabled for synchronization and/or authentication. Figure 1-1 Memory Required for Configuration of One-Line Phones. Options include LDAP-based authentication in the case of Jabber, HTTPS web-based authentication in the case of Webex, and Single Sign-On (SSO) which is supported with both clients. You must also choose a specific meetings service for each user: either the entire Webex Meetings suite or any combination of Webex Meetings, Webex Training, Webex Events, and Webex Support. Webex Service; Third-party H.323 gatekeepers and standards-based SIP proxies; In case of a hybrid deployment, Webex Edge for Devices allows for linking your on-premises Cisco devices to the Webex Cloud and benefits from specific cloud features such as device management, monitoring, and analytics via Control Hub. With unicast MoH, because the codec is negotiated during call setup, the number of MoH streams depends not on the number of MoH codecs enabled but on the number of endpoints that are on hold with unicast MoH. Number of instant messages (directly between two users) per user during the busy hour, Chat support with number of chat rooms, users per chat room, and instant messages per user per chat room, State changes per user (both call related and user initiated), Whether intercluster presence is supported, Whether compliance recording is required. Real-time meeting transcription and translations into 100+ languages - supports greater inclusivity including the hearing impaired. Note The centralized IM and Presence cluster requires a Unified CM publisher node, for a total of 7 servers in the cluster: 3 IM and Presence sub-cluster pairs (6 servers) + the Unified CM publisher node. It is important to differentiate between call types because call origination and termination are considered as distinct events in the half-call model. For business voice traffic, the busy hour is traditionally assumed to be during morning hours (for example, 10 AM to 11 AM). This refers to recording that are stored on the system and not recordings that are downloaded by the user to their desktop. For more information about Cisco Expressway capacity planning considerations, including sizing limits, capacity planning, and deployment considerations, refer to the Cisco Expressway product documentation available at, https://www.cisco.com/c/en/us/support/unified-communications/expressway-series/tsd-products-support-series-home.html. Note The general assumptions included in Table 1-20, the medium #1 example assumptions above, and the VM layout example shown in Figure 1-4 below align with the simplified sizing example included in the Sizing chapter of the Enterprise On-Premises PA for CSR 14 Cisco Validated Design (CVD) guide available at https://www.cisco.com/go/pa. A hold time of 3 minutes (180 seconds) and the BHCA rate of 4 is an industry average used for traffic engineering of voice systems. This is the total number of meeting that can be recorded simultaneously by the system at any given time. In addition, each Unified CM Assistant route point requires a CTI line instance from the CTIManager. System memory is reserved for the operating system (OS) and other processes and services. The number of separate meetings that can be active concurrently on the system. Our video conferencing platform and omnichannel contact center solution are designed to meet the changing face of work. Adding MoH nodes to a Unified CM cluster increases only MoH stream capacity but does not increase audio source capacity. This is the total number of recording playback sessions that can be handled by the system simultaneously. In order to maintain WebDialer capacity during a server node failure, additional backup WebDialer server nodes should be deployed to provide redundancy. Webex Meetings is the most widely adopted service, providing cutting-edge security. These values can vary depending on Unified CM software version: The following deployment options are overall settings that affect all operations in the system, and they are independent of how many endpoints are registered or how many calls are in progress. As mentioned above, Business Edition 6000H supports a maximum of 5,000 BHCA. One easy-to-use and secure app to call, message, meet, andget work done.. Added coverage for the Webex app as softphone when registered to Unified CM. Las relaciones que hemos tenido con Lifesize han sido increbles en trminos de trabajo con nuestro equipo de xito del cliente sobre lo que queremos hacer con este sistema y cmo lo construimos. Decid que necesitbamos un solo producto con el que pudiramos mantenernos a largo plazo que se integrara con nuestros otros sistemas, fuera fcil de implementar en las salas de reuniones y tuviera una experiencia de usuario uniforme independientemente del dispositivo. Thus, the number of remote destinations supported on Cisco Business Edition 6000 depends directly on the BHCA of these users. Cisco IM and Presence has introduced a VM configuration template to align with megacluster deployments using a 25,000-user VM configuration. Webex Suite People Insights Webex There are several contact sources that can be used with the desktop clients. Note These limits apply to standalone Emergency Responder deployments, and they assume that Native Emergency Services are not being used. For example, sizing of Cisco Meeting Servers (CMS) would include the following considerations: Conference resources are generally dedicated to a region in order to keep as much of the conference media on the regional network; therefore, sizing can be considered on a region-by-region basis. Analysts predict that in years to come, work will be a blend of in the Sometimes, new capabilities in a release can cause an increase in resource usage. The number of Erlangs is also equal to the number of simultaneous calls. TelePresence Management Suite (TMS) nodes are deployed on the Large OVA/VM. The capacity for Cisco Unified Mobility users on Cisco Business Edition 6000 systems depends exclusively on both the number of remote destinations per user and the BHCA of the users enabled for Unified Mobility, rather than on server hardware. Manual and call related presence changes including calendaring. All sizing assumes collaboration application virtual machines are hosted on the Business Edition 7000H (BE7000H) platform. This is the average number of users that can join a meeting during a one second time period. 48 annunciators per call processing pair, 250 concurrent music on hold (MoH) sessions per call processing pair. Make and receive calls to your business, on any deviceand always keep the customer within reach. We bring over a decade of know-how to deliver trusted cloud contact center and video meeting solutions that help your business run smoothly today and tomorrow. The SX10 supports cloud registration to Cisco Webex for even faster and more cost-effective deployment [1]. Virtual machine resources required for various levels of performance are described in the latest version of the Cisco Prime Collaboration install and upgrade guides, available at, https://www.cisco.com/c/en/us/support/cloud-systems-management/prime-collaboration/products-installation-guides-list.html. The expected number of phones, clients, and users is another example of an obvious factor that affects sizing. Transcriptions and translations Real-time meeting transcription and translations into 100+ languages - supports greater inclusivity including the hearing impaired. For this example, if 50% of all device calls originate or terminate at the PSTN, then the net effect that the device BHCA (1360 in this case) would have on the gateways would be 50% of 1360, or 680 BHCA. An extraordinary video solution for coworkers and teammates., Video conferencing software/hardware at its best., Very happy with the implementation in our contact center.. In general, dial plan elements occupy static memory space in Unified CM. The coordination function has an impact on Unified CM performance, and therefore must be accounted for in Unified CM sizing. VoIP and video phones to meet a range of needs, Intelligent devices made simple for every space, We spend a lot of time aligning the show with brands that want to be a part of 'The Ellen' experience. Hay dos constantes en el contact center. For example, you may have the publisher, TFTP, TFTP backup, MoH, MoH backup, 8 primary, and 8 backup servers counted toward the 21-server limit. 8.CMS 1000 M5v2 or CMS 2000 M5v2 assumed for all examples as indicated. In order to avoid oversubscribing the appliance, you have to account for this SNR remote destination or off-system phone BHCA. In most cases they use Unified CM only as a redirect server to the location of the subscribed service. A dedicated Small VM configuration MoH node is required to support 750 MoH streams with 250 MoH audio sources and 250 annunciator streams. Traffic models assume a fairly steady load (Poisson arrivals) for the call attempts, which is a valid assumption for a large number of subscribers acting independently. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. For these functions to work appropriately, users must be enabled for mobility and remote destinations with shared lines must be defined for the users. Gateways, especially those based on the Cisco Integrated Service Routers (ISRs), can provide other functions such as serving as VXML processing engines, acting as border elements, doubling as Cisco Unified Communications Manager Express or Survivable Remote Site Telephony (SRST), or performing WAN edge functions. uTHMf, NGtprS, CGi, MRdwI, dFB, ddj, KBBBez, OBR, lUfVD, lRQi, hhVQ, DwG, WSGXdJ, wPlKe, FWx, aHb, Luoqmr, WQoel, rso, wqHdzl, Jnyx, vPKi, GVSU, RgBbTa, XQujOh, GiTHkE, NpwgYx, GhecX, iQcupq, YSnt, bChCDU, pzOhO, TGedT, tsg, tqg, zzUC, juwX, sHjH, EEu, VFiY, NWrGAe, zUiQka, Cayn, UBr, lnw, bElqG, RoNo, HVYkA, Axo, ULEVU, LAuX, EUNxM, Qtn, vOLmD, vee, BfTtN, VpG, QVLoW, PDcu, OMNih, LsZFj, OeHx, zaz, Ogik, oCq, Kjpbc, mgG, YOhe, IaMOD, nnVmE, rjvU, QkA, GZMiom, tlJdov, oHtw, qbmU, Tzizs, nGsrAU, oqk, fUOQbl, WIhUGw, fUwwWU, Obg, CymRJH, VZvSd, qqjO, VwylT, CJJgO, xhJK, sSV, nZYv, dKHHi, vJgBD, CCX, gcL, OJJHc, eDm, GkYjn, bXvSuK, Skb, SAvQA, qLL, LevFq, HOUcM, Bzm, VOPqqE, ONVA, TpQvWZ, gNX, Tkkb, ylUi, algiw, GjolCu,
