both IP communicator and 7942 access MRGL via same device pool. Also, it remote site and using the CUBE at HQ site.  both IP Communicator and 7942 phone use G729 to make external calls and use CUBE MRGL having hardware Conference as first preference and Hardware Transcoding  as second preference.



remote site: region is LID

HQ: region is HQ

its set to use 8Kbps


Device Pool on Hardware Conf use HQ Region


Device pool on Hardware Transcoder use Moh region (G711 with every other region)



The thing is I used the Same device pool on IP Communicator but conference call on IP communicator is working fine. may be i am connected to HQ via vpn and the CUBE is also in HQ. but device pool is same as remote /spoke site.

Couple of questions ...

Do both devices have access to the same MRGL/MRG in CUCM?

Does the 7942's audio codec region match the region of where the disconnected party comes from (ex. PSTN gateway) or does it need transcoded?

hi,



I am facing this  issue in which, when i use the 7942 phone, the conference call fails. it disconnect one of the party and keep it as point to point call. but when i use same settings on ip communicator (connected via vpn), the conference call works. 7942 firmware version SCCP42.9-3-1SR3-1S



CUCM Version: 9.1.2.11900-12
