MOH and RingBack Problems with G729

Unanswered Question
Apr 30th, 2008


Have a h323 trunk between CME and HiPath of Siemens.

With G711ulaw, the ringback, busy tone and moh it's fine!

We changed the codec to g729r8 and g729br8, so, the MOH don't work by h323 trunk. Any site the ringback dont' work, but the busy tone it's fine. In another sites, the ringback it's ok bu the busy tone no!

All it, just the Cisco to HiPath, in HiPath to Cisco, all the rings and tones are ok! Less MOH.

What's the probable problem?


I have this problem too.

Not sure, but when you uploaded the MOH file to the router did you upload in G711 format (default)? or did you convert the MOH file for G729? just something to check..
