MX200, MX300 calls across the WAN

Answered Question
Apr 20th, 2012


I have a sitation where we have telepresence units deployed accross 7 sites. when calls are made between sites, if my region setting is set to g729 between regions, calls will connect Audio Only. when i change my region settings to g711 between regions and try to call again Audio and Video works

is there a setting that i need to turn on in order to successfully make and receive calls between sites on G729 ?


I have my telepresence units registered to UCM 8.6 and the units are running the latest code

I have this problem too.

Hi Cristobal,

Curently the G.729 is not a supported codec for Mx200 and 300.

Audio standards

• G.711

• G.722

• G.722.1

• 64/128 kbps MPEG4 AAC-LD

check the link for more information.

So in my view its not liking this.
