Cisco Cisco TelePresence Management Suite (TMS) Version 15 Maintenance Manual
This diagram shows a TelePresence conference that includes eight legs over multiple protocols.
Cisco TMS uses zones and distribution to define which MCUs will be used depending on the systems
involved in a conference. Zones are also used for routing ISDN.

When booking using any Cisco TMS Extension that relies on the Cisco TMSBA, it is not possible to edit the
route Cisco TMS has created for the conference. The only way to edit the route during booking is to use the
Cisco TMS booking interface.

The Main participant
The most important Cisco TMS concept in routing is the Main participant.
The Main participant is the system that hosts the conference. This can be either an MCU, or a system with
multisite if there are more than two participants. If the conference is point-to-point then either system can be
the Main. If booking from the Cisco TMS web interface, you can choose which participant you want to be the
Main from the drop-down menu.
multisite if there are more than two participants. If the conference is point-to-point then either system can be
the Main. If booking from the Cisco TMS web interface, you can choose which participant you want to be the
Main from the drop-down menu.
Cisco TMS decides which participant will be the Main based on the following criteria:
n
The option selected in:
l
Administrative Tools > Configuration > Conference Settings >
External MCU Usage in Routing
l
Administrative Tools > Configuration > Conference Settings >
Preferred MCU Type in Routing
n
Whether the conference includes immersive endpoints or MCUs with immersive capabilities.
n
IP/ISDN Zones.
n
Which gatekeeper systems are registered to.
n
Which protocol each system supports, for example, whether a gateway or interworking is required.
Note that the weighting given to these criteria can change from one release of Cisco TMS to the next.
Cisco TMS evaluates all possible routes using all possible Main participants (endpoints/MCUs already in the
call and any other MCUs in Cisco TMS). It attaches a weight to every (conference-wide rather than call leg)
