After change tdm board have you notice difference, the issue persist?
No more audio-quality issues after replacing the A500 with a OpenVOX B100p. I forgot to mention we where able to reproduce this issue in our lab, after upgrading wanpipe the problem appeared to be gone - but we didn't test throughly and when we did the same at the clients machine, it didn't have the same effect. Will try to reproduce the problem in the lab again. Regards, Christian

Which version of wanpipe did you upgrade to? I believe a new version has just been released that I am going to try this week. John

We used to have 3.5.24(2011-11-15) and upgraded to 3.5.25(2012-02-21) The Changelog says: - Fixed BRI noise issue: Where a BRI channel could be started in a corrupted state. Didn't help with the noise we experienced though :-(
I've been able to reproduce the issue again in our lab. After starting freeswitch the first few calls where fine, then the choppy noise happened on every call(I repeated about ten times). After restarting wanpipe and freeswitch, the issue is gone and i can't reproduce it for now(Tried for the last 20min)... On 1 March 2012 17:45, Moises Silva <moises.silva@gmail.com> wrote:
Another test you can try to pinpoint the issue and determine once for all if the problem is below FreeSWITCH is to use the "ftdm trace" command. This command will create an input an output file (in the directory you specify) that contains the raw audio as it is read and written from/to the wanpipe device.
I did an ftdm trace when it happened, as Moises suggested - the trace is fine, no noise. Also the RTP-Stream does not show any noise. Since the traces are fine - the problem is happening when the stream leaves freetdm and enters wanpipe according to Moises explanation, right? Best regards, Christian
