VCS X7.2.1 to PBX

[DrVoIP]

Is it possible to create a SIP audio only trunk between a non-cisco PBX that supports SIP trunks and a VCS X7.2.1?   The VCS is installed without a Call Manager and is not part of a CISCO UC deployment.  It is used only for Video conferencing.   We now want people in the non-CISCO pbx to be able to dial into audio only conferences in the VCS.   Has anyone done this?   What are the key issues?

In theory its possible, you just have to create a Neighbor zone and appropriate search rules to point to the Neighbor zone.
