Cisco Cisco TelePresence Management Suite (TMS) Version 15 Maintenance Manual
IP
Cisco TMS supports two call control devices:
■
Cisco TelePresence Video Communication Server
■
Cisco Unified Communications Manager.
Their respective capabilities are listed below:
■
Cisco VCS
—
SIP registrar
—
H.323 gatekeeper
—
can route calls to a Unified CM
■
Unified CM
—
SIP only
—
can trunk calls to a Cisco VCS
For further information on configuring Cisco VCS see:
To configure Cisco VCS with Unified CM see:
Your choice of call control solution will dictate how Cisco TMS routes scheduled calls. For example, for systems
registered to Unified CM, Cisco TMS will assume that the system can only use SIP.

ISDN
Cisco TMS supports:
■
ISDN networks and configuring a dial plan.
■
mixed networks and can route ISDN - > IP and IP -> ISDN.
■
endpoints that have both IP and ISDN capability.
■
connections between IP sites over ISDN.
How Call Protocols are Prioritized
By default Cisco TMS prioritizes H.323 over SIP, and IP over ISDN. You can use zones to specify whether Cisco TMS
prioritizes IP or ISDN, see
prioritizes IP or ISDN, see
You can also configure the following settings in Administrative Tools > Configuration > Conference Settings:
■
Prefer H.323 ID over E.164 Alias: choose whether to favor dialing H.323 ID or E.164 alias when using H.323.
■
Use Flat H.323 Dialing Plan When Routing Calls: Cisco TMS assumes every system can dial every system.
The protocols that Cisco TMS will use to route individual systems in scheduling are set per system in Systems >
Navigator > select a system > Settings > TMS Scheduling Settings.

What Infrastructure Does Cisco TMS Use for Routing?
MCU
An MCU (Multipoint Control Unit) is a conference bridge that can host a number of conferences at the same time
depending on its port allocation. Participants can dial in, or the MCU can dial out to them. Cisco TMS supports the
