I have looked through the archives, and can only find old references to this problem that appear to be no longer relevant, so I thought I'd ask again. I am having a problem with periodic breaks in audio over an IAX trunk. The interruption only happens in one direction, and (I think) only with clients built on the open source libiax. Codec is irrelevant, and jitterbuffer on/off seems to make no difference either. The pause happens every few seconds, and is regular. If I disable trunking, audio is perfect. I am running CVS HEAD as of 1st March. Can anyone shed any light on this? -- =========================================Rod Bacon - VOIP Systems Engineer Empowered Communications Ground Floor, 102 York St. South Melbourne Victoria, Australia. 3205 Phone: +613 99401600 Fax: +613 99401650 ==========================================

Weird..... Florian
I suspect that what you are hearing is the VAD/silence suppression kicking in and out. Unfortunately, I have the same complaints from my users and I have been unable to determine a way to disable silence suppression. VAD=no seems to have no effect in IAX. Also running CVS head from about 2 weeks ago. --------------------------------------- Rod Bacon Thu, 03 Mar 2005 17:05:20 -0800 I have looked through the archives, and can only find old references to this problem that appear to be no longer relevant, so I thought I'd ask again.

Which direction does this happen in, what exactly are these clients you're talking about, and what is does the network look like between the endpoints.
