I have multiple voiceage g729 licenses installed on a RH9 box, and have a remote C7960 configured to use it (low bandwidth). In calls like: Remote C7960 -> g729 -> asterisk -> g711 -> C7960 the audio is oftentimes rather choppy. Changing the remote 7960 to use g711 seems to eliminate/reduce the choppyness. Any ideas on what might be behind this?
What does your sip.conf look like? Always make sure that you have the following codec order for G.729 pass-thru: [general] disallow=all allow=g729 allow=ulaw allow=alaw you don't need to force your C7960 (SIP settings) to use G.729 with the above config. see also: http://www.voip-info.org/tiki-index.php?page=Asterisk%20G.729%20pass-thru Dominique Rich Adamson wrote:> I have multiple voiceage g729 licenses installed on a RH9 box, and have > a remote C7960 configured to use it (low bandwidth).

Hello, Have you checked the CPU load on your asterisk server? If you have no change of codec between the two sides, asterisk just pasts the audio straight through. If there is a change, conversion has to take place and conversion from g729 to anything else does require cpu power. Another thing you could do however is allow the C7960 to use g729 inside sip.conf just not as the first codec, that way it will use g711 but pass on calls direct if g729. Hope that helps Matthew Enger m.enger@xi.com.au On Sat, 2004-06-19 at 01:12, Rich Adamson wrote:> I have multiple voiceage g729 licenses installed on a RH9 box, and have > a remote C7960 configured to use it (low bandwidth).
