We have <br>heard reports that using GCC 4.2 or later with optimizations on causes choppy <br>audio when using GSM.<br><br>Solutions to this include either downgrading your compiler to GCC 4.1 or <br>earlier, or selecting DONT_OPTIMIZE in menuselect under compiler options and <br>then recompiling Asterisk. I also believe that you can set the optimization <br>level for compilation to -O2 in Makefile.rules and have no choppy audio, but I <br>cannot confirm this.<br><br>Of course, if this server isn't running GCC 4.2, then you can ignore everything <br>I've said so far :)<br><br>Mark Michelson<br><br>_______________________________________________<br>-- Bandwidth and Colocation Provided by <a href="http://www.api-digital.com">http://www.api-digital.com</a> --<br><br>AstriCon 2008 - September 22 - 25 Phoenix, Arizona<br>Register Now: <a href="http://www.astricon.net">http://www.astricon.net</a><br><br>asterisk-users mailing list<br>To UNSUBSCRIBE or update options visit:<br> <a href="http://lists.digium.com/mailman/listinfo/asterisk-users">http://lists.digium.com/mailman/listinfo/asterisk-users</a><br></div></blockquote></div><br></div></body></html>
