I get exactly the same thing on a Sangoma B700 board. I raised ticket [#1310] with Sangoma but never got to the bottom of it. Part of the problem was that it was so intermittent and unreproducible in my case. The sad truth (for a perfectionist engineer) is that the users have learned to live with it and priorities are now elsewhere :(. However, I would still like to crack it, of course, and have the ticket still open... For the history in my case, search this group for 'earthspike'.

Hi Brian,

I have attached an a-leg recording of a distorted conference where I play the freeswitch welcome message for testing.

The recording is placed in the dialplan before the conference is created:
<action application="record_session" data="/path/to/recording/test_distortion_${strftime(%Y-%m-%d-%H-%M-%S)}.wav"/>
...
<action application="conference" data="${conference_command}"/>

Hardware is a Sangoma ISDN card (as recommended...).


Best Regards
Melanie

Hi Bob,

thank you very much for your answer and the Dahdi patch (http://jira.freeswitch.org/browse/FS-5898).
However we are using Sangoma and don't know yet how to adapt this patch for our cards.
Does anyone know how to do this?

Melanie
