<div dir="ltr"><span style="font-family:arial,sans-serif;font-size:13px">I have created the following extension:</span><div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">

then i call to this extension, freeswitch dials to <a href="mailto:1001@192.168.1.78" target="_blank">1001@192.168.1.78</a> and when i check the content of SDP, included in a SIP packet,  i see something like this:</div><div style="font-family:arial,sans-serif;font-size:13px">

why my codecs from &#39;absolute_codec_string&#39; are not included in SDP? I would expect to see these lines included:<br><br><div><div>a=rtpmap:8 PCMA/8000</div><div>a=rtpmap:0 PCMU/8000</div><div>a=rtpmap:3 GSM/8000</div>
