I have created the following extension:
<extension name="my_test">
<condition>
<action application="bridge" data="{absolute_codec_string='PCMA,PCMU,GSM'}sofia/external/
1001@192.168.1.78"/>
<action application="hangup"/>
</condition>
</extension>
then i call to this extension, freeswitch dials to
1001@192.168.1.78 and when i check the content of SDP, included in a SIP packet, i see something like this:
v=0
o=FreeSWITCH 1401972565 1401972566 IN IP4 192.168.1.65
s=FreeSWITCH
c=IN IP4 192.168.1.65
t=0 0
m=audio 17262 RTP/AVP 8 0 101 13
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-16
a=ptime:20
why my codecs from 'absolute_codec_string' are not included in SDP? I would expect to see these lines included:
a=rtpmap:8 PCMA/8000
a=rtpmap:0 PCMU/8000
a=rtpmap:3 GSM/8000
