In proxy media mode FS will pass media straight through without any processing. It won't do any transcoding or any SDP modifcation, so it can't transcode PCMU <-> G729 and absolute_codec_string will be ignored - it'll just pass the codec settings straight through from the A leg to the B leg.<br>
<br>So it's expected behaviour.<br><br>-Steve<br><br><br><br><div class="gmail_quote">On 2 August 2010 04:55, Dome Charoenyost <span dir="ltr"><<a href="mailto:dome@tel.co.th">dome@tel.co.th</a>></span> wrote:<br>

I'm not sure it's bug or not ?<br>
I try to test codec negotate. with 3 FS box<br>
FS1 send PCMA to FS2 and FS2 send G729 to FS3<br>
<br>
FS1 -----> [PCMU] ----> FS2 ------> [G729] -------> FS3 (10.20.2.49)<br>
My dialplan<br>
<action application="bridge"<br>
data="{absolute_codec_string='G729'}sofia/internal/<a href="http://2222@10.20.2.49:5080" target="_blank">2222@10.20.2.49:5080</a>"/><br>
It's work fine<br>
When i try<br>
<action application="set" data="proxy_media=true"/><br>
<action application="bridge"<br>
data="{absolute_codec_string='G729'}sofia/internal/<a href="http://2222@10.20.2.49:5080" target="_blank">2222@10.20.2.49:5080</a>"/><br>
Call fail. because FS2 ignore absolute_codec_string='G729' and send<br>
only PCMU (I think by pass from FS1)<br>
<br>
It's bug or not ?<br>
