Yes, PCMU is hardcoded currently from multicaster. I looked into mod_sndfile for decoding PCMU to other codec, but it seems that module is using libsndfile, which reads sound file directly and decode them to L16. If something similar to libsndfile is available, which work on stream instead of file io, then it would surely work.<br>
<br>I don't know how exactly Freeswitch's codec structures & functions work, I am sure decoding can be done by using that, but don't know how to use them.<br><br><div class="gmail_quote">On Sun, Feb 21, 2010 at 7:17 AM, Michael Jerris <span dir="ltr"><<a href="mailto:mike@jerris.com">mike@jerris.com</a>></span> wrote:<br>

This will of course need to match the stream its reading.<div>

Listening on multicast is noting special for multicast, it is just<br>
like reading any other udp socket<br>
