Hi The INVITE would also be interesting.
Does the Contact: Header in the invite contain the transport=tls attribute? Souldn't the 200 OK reply contain at least one Record-Route (the lowest one) stating transport=tls? PS: I was facing a similar issue with a commercial SBC which, when TLS/TCP is not licensed, has the oddity to remove the transport attribute from the contact header and send new transactions in the same dialog without specifying transport (defaulting to UDP). So I had to create a copy the value of the transport header to a custom t= contact attribute, which I then use to restore the U-URI transport attribute towards the registrar handling the CPE connection. > 200 OK from carrier > SIP/2.0 200 OK > Via: SIP/2.0/TLS > KAM_PUB_IP:5061;branch=z9hG4bK18ff.3d856b8b0b007414ab2dec09cbabd574.0;i=a2 > Via: SIP/2.0/TLS > FS_PUB_IP:5061;received=FS_PUB_IP;rport=56403;branch=z9hG4bKKaee61yyZ98De > From: "+14388006102" <sip:+14388006102@KAM_PUB_IP>;tag=XjQ5g4Ze5UaZp > To: <sip:933@CARRIER_PUB_IP:5061;transport=tls>;tag=gK04d33797 > Call-ID: b99c2b65-a827-123d-1984-4201c0a80193 > CSeq: 84807919 INVITE > Record-Route: > <sip:KAM_PUB_IP:5061;transport=tls;lr;ftag=XjQ5g4Ze5UaZp;did=aad.91c1;nat=yes> > Accept: application/sdp, application/isup, application/dtmf, > application/dtmf-relay, multipart/mixed > Contact: <sip:933@CARRIER_PUB_IP:5061> > Allow: > INVITE,ACK,CANCEL,BYE,REGISTER,INFO,SUBSCRIBE,NOTIFY,PRACK,UPDATE,OPTIONS,MESSAGE,PUBLISH > Require: timer > Supported: timer > Session-Expires: 1800;refresher=uac > Content-Length: 324 > Content-Disposition: session; handling=required > Content-Type: application/sdp > > v=0 > o=Sonus_UAC 913845 351585 IN IP4 CARRIER_PUB_IP > s=SIP Media Capabilities > c=IN IP4 206.146.100.22 > t=0 0 > m=audio 33168 RTP/SAVP 0 101 > a=crypto:1 AES_CM_128_HMAC_SHA1_80 > inline:LfSgFSVqhXNWMSziOtwpEeYmNu0/kGiyuMVS8VXy > a=rtpmap:0 PCMU/8000 > a=rtpmap:101 telephone-event/8000 > a=fmtp:101 0-15 > a=sendrecv > a=ptime:20 > > > ACK Kam is sending > > ACK sip:933@CARRIER_PUB_IP:5061 SIP/2.0 > Via: SIP/2.0/UDP > KAM_PUB_IP:5060;branch=z9hG4bK18ff.f8c56ea9cad44dc10408188224b923cf.0;i=a2 > Via: SIP/2.0/TLS > FS_PUB_IP:5061;received=FS_PUB_IP;rport=56403;branch=z9hG4bKmK767vF2vjZ0S > Max-Forwards: 69 > From: "+14388006102" <sip:+14388006102@KAM_PUB_IP>;tag=XjQ5g4Ze5UaZp > To: <sip:933@CARRIER_PUB_IP:5061;transport=tls>;tag=gK04d33797 > Call-ID: b99c2b65-a827-123d-1984-4201c0a80193 > CSeq: 84807919 ACK > Contact: <sip:mod_sofia@FS_PUB_IP:5061;transport=tls;alias=FS_PUB_IP~56403~3> > Content-Length: 0 > __________________________________________________________ > Kamailio - Users Mailing List - Non Commercial Discussions > To unsubscribe send an email to [email protected] > Important: keep the mailing list in the recipients, do not reply only to the > sender! > Edit mailing list options or unsubscribe: > Mit freundlichen Grüssen -Benoît Panizzon- -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________ __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions To unsubscribe send an email to [email protected] Important: keep the mailing list in the recipients, do not reply only to the sender!
