[Asterisk-Users] Audio Drops out at Random - one way
Have a strange problem. 2 different asterisk servers, running different CVS. One behind Firewall, one not. Cisco 7940 phones. Over the past two weeks, users have had a problem with one way audio, after about 2 minutes into a call, they can hear the other person, but the other person cannot hear them, this happens for about 3-5 seconds, then all is fine again. It doesn't happen on every call, about one in 5. Hardware is good, 2mb Connection, QOS enabled. If it was only one Asterisk server I would be ok, but it happens on two completely different places. I cannot work out what is causing it, can anyone offer anyone offer a solution or a method to track this down. Thanks. -------------- next part -------------- An HTML attachment was scrubbed...

[Asterisk-Users] Audio Drops out at Random - one way
Sorry forgot to mention this is with IAX2 only, SIP works fine. ________________________________ From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Craig Waddington Sent: 29 November 2004 10:46 To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] Audio Drops out at Random - one way Have a strange problem. 2 different asterisk servers, running different CVS.

No one seems to be able to help and I have replaced or reinstalled just about every component in the chain except the internet itself and the termination provider.. Have updated Asterisk to 1.0.2, have added a switch to my network (was using a hub), have changes to a different firewall, have setup port mapping through the NAT, have tried different DSL routers and put in a high quality microfilter.. So the only things I think it can be are a) my termination provider (but they service many people and I am sure others would have brought it up if it was a problem), b) Asterisk itself or c) my DSL line or ISP.. Unfortunately these are all hard to check and the debug logging on Asterisk didn't help much when I tried looking at it.. I know this doesn't help much but if you come up with anything please let me know.. Its driving us crazy having calls drop on us especially when talking to customers.. Later..

I found this: http://lists.digium.com/pipermail/asterisk-dev/2003-May/000764.html But it is old, and I am sure lots of changes have been made to the source, since then. Where and how do you set absolutetimeout=0, would this help? A test I want to perform is, we make a call, and say nothing for 20 seconds, and see if that's why the audio stream is being dropped. ??? What I am doing currently is running debug IAX2 when users make a call, to try pinpoint the issue, but I don't know what I am looking for in the output. Are you using Cisco Phones? If so, what firmware, that is the only common thing at my end. This install worked fine for months, the audio issue has just started occurring. The quality is perfect, except this loss of Audio for a few seconds. Is your problem purely outgoing? -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of WipeOut Sent: 29 November 2004 13:01 To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] Audio Drops out at Random - one way Craig Waddington wrote:> Have a strange problem. > > 2 different asterisk servers, running different CVS. > > One behind Firewall, one not. > > Cisco 7940 phones. > > Over the past two weeks, users have had a problem with one way audio, > after about 2 minutes into a call, they can hear the other person, but> the other person cannot hear them, this happens for about 3-5 seconds,> then all is fine again. > > It doesn't happen on every call, about one in 5. > > Hardware is good, 2mb Connection, QOS enabled. > > If it was only one Asterisk server I would be ok, but it happens on > two completely different places. > > I cannot work out what is causing it, can anyone offer anyone offer a > solution or a method to track this down. > > Thanks. > >------------------------------------------------------------------------> > >I have a similar problem with my IAX connection to my termination provider..
