Unified Communications on Cisco Integrated Services Routers
IP Media Services
The Cisco 3900 series and Cisco 2900 series ISRs support the following media services:
•
•
•
Conferencing, Transcoding and Media Termination Point (MTP)
Cisco Enhanced Conferencing and Transcoding for Voice Gateway Routers provides conferencing and
transcoding capabilities in Cisco IOS Software-based gateways using the onboard Cisco Packet
Voice/Fax Digital Signal Processor Modules on the Cisco voice gateway routers. This capability is also
supported on Cisco voice gateway router platforms using the Cisco IP Communications Voice/Fax
Network Module and the Cisco IP Communications High-Density Digital Voice/Fax Network Module.
This feature is delivered in Cisco IOS Software and operates in conjunction with Cisco CallManager.
See Configuring Enhanced Conferencing and Transcoding for Voice Gateway Routers at Cisco.com for
configuration information,
RSVP Agent
The RSVP Agent feature implements a Resource Reservation Protocol (RSVP) agent on Cisco IOS voice
gateways that support Cisco Unified Communications Manager Version 5.0.1. The RSVP agent enables
Cisco Unified Communications Manager to provide resource reservation for voice and video media to
ensure QoS and call admission control (CAC). Cisco Unified Communications Manager controls the
RSVP agent through Skinny Client Control Protocol (SCCP). This signaling is independent of the
signaling protocol used for the call so SCCP, SIP, H.323, and MGCP calls can all use the RSVP agent.
Benefits of this feature include the following:

Trusted Relay Point (TRP)
The Cisco Unified Communications system can be deployed in a network virtualization environment.
Cisco Unified Communications Manager enables the insertion of trusted relay points (TRPs). The
insertion of TRPs into the media path constitutes a first step toward VoIP deployment within a virtual
network.
