I have a server with Asterisk 1.4.21.1 and some prompts recorded in GSM format. I have these same prompts in another server with Asterisk 1.4.18, on this server the prompts sound pretty nice, but on the first one they sound pretty choppy. Was there any changes on the transcoding code between this 2 versions ? Any hints ?

I would make absolutely sure you've got your linux distro's version of libgsm installed. I can't really speak to the difference between those two versions of Asterisk without looking at a change-log, but I highly doubt a serious modification to the gsm code took place between sub- versions. Hope this helps, - Darren _____________________________ dmsessions at gmail.com http://www.darrensessions.com http://www.linkedin.com/in/dsessions _____________________________ On Aug 6, 2008, at 7:02 AM, Guilherme Loch Waltrick G?es wrote:> I have a server with Asterisk 1.4.21.1 and some prompts recorded in > GSM format.

We have heard reports that using GCC 4.2 or later with optimizations on causes choppy audio when using GSM. Solutions to this include either downgrading your compiler to GCC 4.1 or earlier, or selecting DONT_OPTIMIZE in menuselect under compiler options and then recompiling Asterisk. I also believe that you can set the optimization level for compilation to -O2 in Makefile.rules and have no choppy audio, but I cannot confirm this. Of course, if this server isn't running GCC 4.2, then you can ignore everything I've said so far :) Mark Michelson
