Re: [SR-Users] SDPOPS issue or append_hf

Hello, To be sure that the issue is not coming from append_hf, I add (…,”Call-ID”). The PAI is now inserted after the Call-ID. But, the issue remains: Content-Type: application/sdp Content-Length: 169 v=0 o=UserA 1153072414 140968390 IN IP4 A.B.C.D s=Session SDP c=IN IP4 A.B.C.D t=0 0 m=audio 60412 RTP/AVP 8 a=rtpmap:8 PCMA/8000 a=nortpproxy:yes This SDP is dropped. Someone see something missing or wrong in the SDP parts?

If the calling party sends only one codec description like: Content-Type: application/sdp Content-Length: 202 v=0 o=UserA 2966746938 1790378070 IN IP4 10.141.0.21 s=Session SDP c=IN IP4 10.141.0.21 t=0 0 m=audio 49152 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 The result of the function “sdp_keep_codecs_by_name("PCMA,PCMU,G729a");” is: Content-Type: application/sdp Content-Length: 170 P-Asserted-Identity: "+0123456789" <sip:+0123456789@sip.tld> v=0 o=UserA 2485672881 3000549892 IN IP4 a.b.c.d s=Session SDP c=IN IP4 a.b.c.d t=0 0 m=audio 40330 RTP/AVP 8 a=rtpmap:8 PCMA/8000 a=nortpproxy:yes If I open the capture in Wireshark, the PAI is not in the SDP part, and the end of the capture after “a=rtpmap:8 PCMA/8000” is seen as “Data (18 bytes)”. I don’t understand why the PAI is inserted within the SDP part. Adding the PAI is done after “sdp_keep_codecs_by_name”: if (!is_present_hf("P-Asserted-Identity")) { $var(pai) = $(fU{re.subst,/^0/+33/g}); append_hf("P-Asserted-Identity: \"$var(pai)\" <sip:$var(pai)@$fd <sip:$var%28pai%29@$fd>>\r\n"); } I guess that this cause my INVITE being dropped by 488 Media Not Acceptable Here.
