Introducing Cisco Unified Communications Manager Express Cisco Unified Communications Manager Express provides call processing for Cisco IP Phones for small-office or branch-office environments. It enables the large portfolio of Cisco Integrated Services Routers to deliver unified communications features that are298 Implementing Cisco Unified Communications Voice over IP and QoS (CVoice) Foundation Learning Guide commonly used by business users to meet voice and video communications requirements of the small or medium-sized office. This section introduces the key features and functionality of Cisco Unified Communications Manager Express and explains what is required to deploy it on Cisco IOS routers. Fundamentals of Cisco Unified Communications Manager Express Cisco Unified Communications Manager Express extends enterprise telephony features and functions to packet telephony network devices. These packet telephony network devices include Cisco IP Phones, media-processing devices, VoIP gateways, and multime- dia applications. Cisco Unified Communications Manager Express provides these functions: ■ Call processing: Call processing refers to the complete process of routing, originat- ing, and terminating calls, including any billing and statistical collection processes. ■ Signaling and device control: Cisco Unified Communications Manager Express sig- nals calls between endpoints and directs devices such as phones, gateways, and con- ference bridges to establish and tear down streaming connections. ■ Dial plan administration: The dial plan is a set of dial peers that Cisco Unified Communications Manager Express uses to determine call routing. Cisco Unified Communications Manager Express provides the ability to create scalable dial plans. ■ Phone feature administration: Cisco Unified Communications Manager Express offers services such as hold, transfer, forward, conference, speed dial, last-number redial, Call Park, and other features to Cisco IP Phones and gateways. ■ Directory services: Cisco Unified Communications Manager Express stores user- and phone-related data in the NVRAM of a Cisco IOS router. ■ Direct access to gateway features and modules: Cisco Unified Communications Manager Express runs on a Cisco IOS router and has direct access to the digital sig- nal processor (DSP) resources and modules that are installed in it. While CUCME acts as a call processing solution, keep in mind that CUCME is only one of Cisco’s call processing solutions. Cisco Unified Communications Manager Express Positioning Cisco offers four product options for call processing, as follows: ■ Cisco Smart Business Communications System: This product runs on the Cisco Unified Communications 500 Series for Small Business platform and supports up to 104 users.Chapter 3: Supporting Cisco IP Phones with Cisco Unified Communications Manager Express 299 ■ Cisco Unified Communications Manager Express: This platform runs on the Cisco Integrated Services Routers (that is, ISR and ISR2) and offers support for as many as 365 users. ■ Cisco Unified Communications Manager Business Edition: This software product runs on Cisco 7800 Series Media Convergence Servers and supports up to 500 users. ■ Cisco Unified Communications Manager: This software product runs on Cisco 7800 Series Media Convergence Servers or a Cisco Unified Computing System. The Cisco Unified Computing System reduces the number of devices that must be purchased, cabled, configured, powered, cooled, and secured. The solution delivers end-to-end optimization for virtualized environments while retaining the ability to support tradi- tional operating system and application stacks in physical environments. It is well suited for the largest Cisco Unified Communications Manager deployments, for as many as 30,000 users per cluster. Cisco Unified Communications Manager Express Deployment Models Architecturally, CUCME can be deployed in either a single-site or a multisite deployment. Single-Site Deployment Single-site deployments, an example of which is provided in Figure 3-1, use the public switched telephone network (PSTN) communications for all offsite voice traffic. One Cisco Unified Communications Manager Express site supports as many as 365 Cisco IP Phones. If a Cisco Unity Express module is installed in the router, voice-mail service is also available. Internet V CIsco Unified PSTN Communications Manager Express/ Cisco Unity Express Figure 3-1 Single-Site CUCME Deployment300 Implementing Cisco Unified Communications Voice over IP and QoS (CVoice) Foundation Learning Guide Multisite Deployment Multisite deployments place VoIP calls between sites, as shown in Figure 3-2. When the H.323 protocol is used for communications between clusters, an H.323 gatekeeper can be used for call routing and call admission control (CAC). Remote sites can be Cisco Unified Communications Manger clusters or Cisco Unified Communications Manager Express sites. V CIsco Unified Communications Manager Express/ Cisco Unity Express PSTN CIsco Unified Communications Manager Express/ CIsco Unified Communications Cisco Unity Express Manager Express/ Cisco Unity Express V V Internet/ WAN Gatekeeper Unified Messaging Gateway Figure 3-2 Multisite Deployment When voice-mail networking is required, a Cisco Unified Messaging Gateway provides a centralized Voice Profile for Internet Mail (VPIM) routing and resolution service. This service routes calls between voice-mail systems using Simple Mail Transfer Protocol (SMTP) to deliver voice mail that was recorded at the source, adding the message as an attachment to an email message that is sent to the destination. The Cisco Unified Messaging Gateway synchronizes its local database with all the registered voice-mail sys- tems to create a global voice-mail directory. Any user wishing to send the same voice mail to people located in multiple sites looks up the recipients in the global directory and assigns them as needed to a single voice-mail message. The message is then relayed through the Cisco Unified Messaging Gateway to all the recipients, without placing a sin- gle external phone call.Chapter 3: Supporting Cisco IP Phones with Cisco Unified Communications Manager Express 301 Cisco Unified Communications Manager Express Key Features and Benefits Cisco Unified Communications Manager Express allows small- to medium-sized busi- nesses and autonomous small enterprise branch offices to deploy voice, data, and IP telephony on a single platform, therefore streamlining operations and lowering network costs. Cisco Unified Communications Manager Express is ideal for customers who have data connectivity requirements and have a need for a telephony solution in the same office. Whether offered through the managed service offerings of a service provider or purchased directly by a corporation, Cisco Unified Communications Manager Express offers most of the core telephony features required in a small office, and many advanced features not available with traditional telephony solutions. The ability to deliver IP teleph- ony and data routing using a single converged solution allows customers to optimize their operations and maintenance costs, resulting in a very cost-effective solution that meets office needs. Because the solution is based on Cisco IOS Software, it builds on convergent networks that include content networking, video, quality of service (QoS), firewall, and XML services. Administration and management are accomplished through either the familiar Cisco IOS Software command-line interface (CLI) or a web-based GUI.

Figure 3-3 shows a few platform examples.304 Implementing Cisco Unified Communications Voice over IP and QoS (CVoice) Foundation Learning Guide Cisco 1861 Series Router Cisco 2900 Series Router Cisco 3900 Series Router Figure 3-3 Examples of Supported Platforms Note Cisco 2900 and 3900 Series Integrated Services Routers are referred to as Generation 2 (G2) router platforms. These platforms have varying levels of scalability, as discussed in the following sections. Cisco Integrated Services Routers Scalability Some platforms support a higher number of phones in SRST mode than in Cisco Unified Communications Manager Express mode. SRST mode is enabled only during WAN fail- ures, when branch phones lose IP connectivity to the Cisco Unified Communications Manager cluster and fall back to the local SRST gateway. Table 3-1 contrasts the number of supported IP phones for various ISR router models, both for SRST operation and for CUCME operation.Chapter 3: Supporting Cisco IP Phones with Cisco Unified Communications Manager Express 305 Table 3-1 Scalability of ISR Routers Router Model Phones Supported in Phones Supported by SRST Mode CUCME Cisco 1861 15 15 Cisco 2801 25 25 Cisco 2811 35 35 Cisco 2821 50 50 Cisco 2851 100 100 Cisco 3825 350 175 Cisco 3845 730 250 Cisco Integrated Services Routers Generation 2 Scalability Cisco 3925 and 3945 platforms support a higher number of phones in SRST mode than in regular Cisco Unified Communications Manager Express mode, as shown in Table 3-2.

This license is based on the number of endpoints to be deployed. Each Cisco IP Phone or Cisco ATA port requires a Cisco Unified Communications Manager Express seat license. The following are the requirements for a CUCME release on a supported router: ■ Cisco IOS Software Release 15.0.1M or greater ■ IP voice feature set for Cisco IOS Software ■ The appropriate amount of flash memory and RAM in the routerChapter 3: Supporting Cisco IP Phones with Cisco Unified Communications Manager Express 307 You need to download and configure additional files if you want to use the optional GUI or Cisco Configuration Professional. Also, you need to download and install the firmware files for the models of phones that you choose to deploy with Cisco Unified Communications Manager Express. You can retrieve these files from Cisco.com, with appropriate login credentials. Cisco Integrated Services Routers Generation 2 Licensing Model Cisco Generation 2 platforms (Cisco 2900 and 3900 Series Integrated Services Routers) introduce a new licensing approach that uses license-based software activation. A univer- sal Cisco IOS image is combined with multiple package options. The new CUCME and SRST bundles for the G2 routers provide the entry level for 25 user seats across all plat- forms. The bundles include unified communications technology packets, flash, and DRAM. Currently, the software activation license approach is not yet implemented for Cisco Unified Communications Manager Express or SRST. For these features, the old- style, owner-based, right-to-use licensing approach is still in place. The licensing for Cisco Unified Communications Manager Express and SRST is interchangeable within the same number of user counts, for investment protection purposes. Licenses can be trans- formed from a Cisco Integrated Services Router–based platform into a Cisco Integrated Services Router G2–based platform. Figure 3-4 illustrates the difference between Cisco Integrated Services Router–based and Cisco Integrated Services Router G2–based licensing. The Cisco Integrated Services Router license includes two components: the platform-related CUCME or SRST feature license, and the per-seat feature license (either Cisco Unified Communications Manager Express or SRST). The Cisco Integrated Services Router G2 package is related to the Cisco 2900 or 3900 Series and includes three components.

Cisco Unified Communications Manager Express Operation Figure 3-5 illustrates the operation of Cisco Unified Communications Manager Express running on a voice gateway that is connected to the PSTN over a digital trunk. It has mul- tiple Cisco IP Phones registered to it. The registered phones can make calls to each other. The calls are signaled by exchanging messages between the phones and the CUCME, but the media flows directly between the phones. The gateway routes calls to external desti- nations over the dial peer that uses the T1 channelized controller. When making and receiving calls to and from the PSTN, the gateway typically performs digit manipulation in the calling (ANI) and called numbers (Dialed Number Identification Service DNIS). With this approach, numbers are made routable in the PSTN and are shortened to internal numbers within the enterprise network. 1001 DNIS: 1001 DNIS: 555-1001 Cisco Unified Communications DNIS: 9-555-2001 DNIS: 555-2001 Manager Express T1 1/0/0 555-2001 PSTN 1002 V IP phone side: Digit PSTN side: Virtual dial peers Manipulation dial-peer voice 1 pots created automatically incoming called-number . for phone extensions 1003 direct-inward-dial dial-peer voice 10 pots destination-pattern 9T port 1/0/0:23 Figure 3-5 Call to and from PSTN Operation of Cisco Unified Communications Manager Express It is important to be able to distinguish between various Cisco Unified Communications end-user devices that you might encounter during the course of deploying and adminis- tering a Cisco Unified Communications network. In addition, understanding the boot and registration communication between a Cisco IP Phone and a Cisco UnifiedChapter 3: Supporting Cisco IP Phones with Cisco Unified Communications Manager Express 309 Communications Manager Express is critical for understanding normal voice network operations and for troubleshooting. This section introduces the endpoints supported by Cisco Unified Communications Manager Express and describes their features. Overview of Cisco Unified Communications Manager Express Endpoints A variety of endpoints, including Cisco products as well as third-party products, can be used with Cisco Unified Communications Manager Express. The endpoints include Cisco IP Phones, analog station gateways (which allow analog phones to interact with CUCME), and video endpoints. Cisco Unified Communications Manager Express supports two protocols used by for endpoints: Skinny Client Control Protocol (SCCP) and Session Initiation Protocol (SIP). Endpoint Signaling Protocols From a feature support perspective, the protocols can be categorized into three groups: ■ SCCP: SCCP is a Cisco-proprietary protocol and typically is used only by Cisco Unified IP endpoints. SCCP offers a large set of telephony features, most of which are supported on all Cisco IP Phone models. ■ Standard SIP: Cisco Unified Communications Manager Express supports standards- based SIP endpoints. The number of standardized telephony features, however, is limited compared to feature-rich SCCP. ■ Cisco Unified Communications Manager Express SIP support for Cisco IP Phones: When Cisco Unified Communications Manager Express interacts with Cisco IP Phones using the SIP protocol, many features are supported in addition to the stan- dard feature set of SIP. CUCME supports similar features for Cisco IP Phones sup- ported with SCCP, but the number of features that are supported depends on the par- ticular model of Cisco IP Phone. Endpoint Capabilities Cisco IP Phones cover a wide range of types, from simple, display-less, entry-level phones to upper-level phones with high-resolution, color, touchscreen displays. Differences in hardware-related capabilities include the following: ■ Screen: Different models have screens with different resolution, size, color, and touchscreen capabilities. ■ Codec support: All Cisco IP Phones support G.711 and G.729 codecs. High-end models also support Internet Low Bitrate Codec (iLBC) and wideband codecs for superior voice quality.310 Implementing Cisco Unified Communications Voice over IP and QoS (CVoice) Foundation Learning Guide ■ LAN: Most IP phones have a PC port, so that a PC can be connected to the network without requiring its own wall socket, in-house cabling, and physical switch port. Different phone models support different speeds on the PC port and on the IP phone switch port (the port that is connected to a LAN switch). ■ Navigation and feature buttons: The number of IP phone buttons, softkeys, and other buttons also differs per phone model. There are also differences in the type of navigation clusters (two-way or four-way). ■ Speakerphone and headset support: Some IP phones offer speakerphone and head- set support. ■ Number of lines: The number of lines also differs per phone model. ■ Other features: Some IP phones provide other special features such as video, Wi-Fi support, or dedicated support for use in conference rooms (for example, enhanced speakerphone capabilities, including the option to connect multiple microphones). Basic Cisco IP Phone Models Basic Cisco IP Phones include these models: ■ Cisco Unified IP Phones 7906 and 7911: These phones fill the communications needs of cubicle, retail, classroom, or manufacturing workers, or anyone who con- ducts low-to-moderate telephone traffic. Four dynamic softkeys guide users through core business features and functions, while a pixel-based display combines standard features, calling information, and XML services. Both phones offer numerous impor- tant security features, plus the choice of IEEE 802.3af Power over Ethernet (PoE), Cisco inline power, or local power through an optional power adapter.
