LAN that are using XML services to directly connect to the radio via the multicast features on Cisco
IOS. The LMR can be integrated with the E&M port on the gateway; the commands on the gateway
support this router-to-radio adaptation.
This document provides a workaround method that bridges the multicast VoIP to unicast VoIP using
a physical T1 loopback. This is not an essential configuration. It is documented to demonstrate how
you can integrate multicast VoIP audio into standards-based VoIP call-control schemes such as
Skinny, H.323, or SIP. IP–to–IP gateway is the preferred and recommended option to use for
bridging between standards-based VoIP protocols. The VoIP-to-multicast bridge using a physical
loopback can also be used for local multi-party conferencing via Cisco CallManager Express (Cisco
CME) phones or PSTN phones.
Onboard DSPs are used for the voice modules on the WAN interface car (WIC) slots
Cisco CallManager seamlessly connects to Cisco CME over an H.323 trunk defined on the Cisco
CallManager [Release 3.3 (3) or later].
Cisco CME (Release 3.2) manages the local phone network. Cisco CME and Cisco Unity Express
enable users to use a gateway as though it were a PBX coupled to a voice-mail system.
Cisco Unity Express (with Cisco Service Engine 1.1) on the NM-CUE provides voice-mail and
auto-attendant services.
Cisco CME seamlessly integrates with the Cisco CallManager at the headquarters site and supports
all supplementary services.
Content Engine (CE) modules support web caching, video–on–demand and live-splitting
applications.
Cisco Access Control Network Server (ACNS) on CE (ce2636-sw-5.1.3) saves WAN bandwidth by
web-caching and splitting streaming video over unicast and multicast.
