You are misunderstanding the message, and this why in general we ask users who are not well versed in how Asterisk works to *not* enable the DEBUG messages on the console. What you are seeing is *not* Asterisk changing the format of the audio stream between it and the provider, but instead it is changing the internal 'write format' of the channel to GSM (by putting a GSM to ULAW transcoder in the path). It is doing this because you are running an application that wants to play sound files, and you don't have ULAW sound files installed. Since the only sound files you have are GSM, it has to transcode that to ULAW before sending it out the channel. -- Kevin P.
