Hello,<br><br>AS freeswitch modifies SDP ( Media Description & Media Attributes) so is there any way to just bypass that process.<br><br>Regards<br>Sam<br><br><br><div class="gmail_quote">On Thu, Apr 14, 2011 at 6:32 PM, Steven Ayre <span dir="ltr"><<a href="mailto:steveayre@gmail.com">steveayre@gmail.com</a>></span> wrote:<br>

<br>I mean there are different better ways to avoid transcoding.<br><br>What you suggested with bridge should indeed avoid it. Without the absolute_codec_string the bleg would be offered all codecs supported by FS which may be more than supported by the caller, however with that setting it would only offer those supported by both the caller and FS. The callee will pick one it supports (or return 488 Not Acceptable Here). The aleg will then use the same codec as the bleg, so at that point both legs will be using the same codec so no transcoding will take place (unless you try using something like eavesdrop/record). You could then if you wanted handle the 488 Not Acceptable Here by redialing without absolute_codec_string to try again, this time the bleg could use a different codec than the aleg (transcoding).<br>

Do you mean<br>
<br>
set proxy_media=true<br>
<br>
is the equivalent of<br>
<br>
set late_negotiation=true<br>
bridge {absolute_codec_string=${ep_codec_string}}blah<br>
<br>
and transcoding will never happen?<br>
