For the record, line #107 contains the codecs (and other stuff) that FS offered:<div><br></div><div><span class="Apple-style-span" style="color: rgb(51, 51, 51); font-family: 'Courier New', Courier, monospace; font-size: 11px; background-color: rgb(255, 255, 255); ">m=audio <span class="nu0">16480</span> RTP/AVP <span class="nu0">8</span> <span class="nu0">0</span> <span class="nu0">9</span> <span class="nu0">101</span> <span class="nu0">13</span></span><br>
<br>The "8 0 9 101 13" represent the codecs (and other stuff). What do those numbers mean? This wiki page has the list:</div><div><br></div><div><a href="http://wiki.freeswitch.org/wiki/RTP_payload_list">http://wiki.freeswitch.org/wiki/RTP_payload_list</a></div>
<div><br></div><div>The SDP spec says that for non-dynamic payload numbers you are NOT required to have the "a=rtpmap" lines. This makes sense because those payload numbers don't change meaning until you get up to 96 and higher. The issue is that some devices are broken and require the "a=rtpmap" lines for the payload types below number 96. The verbose_sdp chan var mentioned by KK tells FS to add all those a=rtpmap lines for the non-dynamic payload types. You should only set this var when absolutely necessary because those verbose SDP's can cause the packets to be larger than the allowable MTU size.</div>
