VCS and MCU supporting both H.323 and SIP
Follow the processes above and set up the VCS to work with an H.323 MCU and also to work with a SIP
MCU.

It is very important that the priority of the neighbor zone search rule for the SIP MCU is the same value (48 in
this example) as the priority for the Local Zone search rule that takes the received conference URI and
converts it to an E.164 number.

converts it to an E.164 number.
When the VCS is routing calls, at any particular match priority value, it routes the call in native protocol in
preference to interworking the call. By setting a priority of 48 for both the SIP route to the MCU and the H.323
route to the MCU, SIP calls will be routed using the SIP neighbor zone, and only if that were to fail would the
VCS try to interwork the call to H.323. Similarly H.323 calls are routed to the H.323 registration in preference
to being interworked to SIP.

To support both SIP and H.323 conferencing, the MCU must be running version 3 or later software.
VCS with H.323 endpoints initiating a Multiway conference
The Multiway Conference Factory functionality is SIP based. To allow H.323 endpoints to initiate a Multiway
conference:

.
2. Set H.323 <-> SIP interworking mode to Registered only (or On is also acceptable).
