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.
