Unified Communications, Collaboration, and Voice-Gateway Services

The Cisco 2900 Integrated Services Router is the foundation for collaboration in the small and midsize branch

office, serving as a critical component of a Cisco's video architecture (Medianet) and enterprise Unified

Communications solution. With embedded voice services and a wide range of supported telephony interfaces, the

Cisco 2900 Series delivers maximum deployment flexibility for the distributed enterprise. Unified communications is

enabled through a rich signaling and media-processing infrastructure, including a variety of protocols, media

interworking, signal and media security, transcoding, conferencing, and QoS. Cisco Integrated Services Routers

also feature a wide range of voice-gateway interfaces, supporting a broad array of signaling and physical network

interfaces.

The Cisco 2900 Series enables a full range of existing and emerging video services, with scaling improvements to

support Cisco TelePresence

conferencing, security, and session control. The Cisco Unified Border Element

extends these capabilities for business-to-business TelePresence communications. The Cisco 2900 Series adds

support for the new Cisco High-Density Packet Voice Digital Signal Processor (DSP) Module (PVDM3), which has

been optimized for voice and video support. The new PVDM3 modules support all voice-gateway functions of

earlier generations of PVDMs and add higher density and more processing power to support emerging rich-media

applications. The Cisco 2900 Series provides 2 or 3 onboard PVDM3 slots, depending on the platform.

Cisco Unified Communications Manager Express and Survivable Remote Site Telephony

The Cisco Integrated Services Routers natively provide optional unified communications services within the Cisco

IOS Software, minimizing the IT hardware footprint and total cost of ownership at the branch office. Cisco Unified

Communications Manager Express (CME) provides a broad range of IP private-branch-exchange (PBX) and key-

system features integrated into the router for the small and midsize branch office. Cisco Survivable Remote Site

Telephony (SRST), also inherently available in Cisco IOS Software, and an option on the Cisco 2900 Series, helps

ensure that branch-office employees have uninterrupted telephony services and features, even if the connection to

a centralized Cisco Unified Communications Manager is disrupted.

Coupled with Cisco Unity

Express, the integrated solution for voicemail, Automated Attendant, and interactive

voice response (IVR), the Cisco 2900 Series offers the branch office a complete range of unified communications

services while delivering industry-leading security within a single platform.

VoiceXML Application Services

The Cisco 2900 Series also supports standards-certified VoiceXML browser services. VoiceXML is an open-

standard markup language used to create voice-enabled web browsers and IVR applications. Just as HTML

enables you to retrieve data with a PC, VoiceXML enables you to retrieve data using voice or dual-tone-

multifrequency (DTMF) telephony input. The Cisco 2900 Series can deliver a much higher range of concurrent

voice-gateway services combined with VoiceXML browser services, for up to 200 sessions on the Cisco 2951.

Cisco Unified Border Element

The Cisco Unified Border Element capabilities supported on the Cisco 2900 Series address the emerging

requirements in an IP-centric interconnect for branch-office unified communications between enterprises and

service provider networks. Cisco Unified Border Element provides intelligent border-element functions such as

physical and logical ingress and egress demarcation points, signaling and media control, and consolidated security

and management features. The Cisco 2900 Series supports higher scale than previously provided on the Cisco

2800 Series, up to three times the number of sessions.
