<div dir="ltr"><div>Hello all,</div><div><br></div><div>I am having a situation where 200 OK from a GW arrives at FS and can be seen in FS CLI but no ACK is generated. Here in INVITE and 200 OK packets I am wondering what are the problematic headers I know contact is messy though. Shouldn't it at least generate an ACK ?.<div><br></div><div><div>PUBLIC-IP:5070 = FS</div><div>PUBLIC-IP or PUBLIC-IP:5060 = GW(Kamailio)</div><div><br></div><div>-------------------------- INVITE -------From FS to GW--------------------</div><div> INVITE <a href="mailto:sip%3A81205999@public.domain.com">sip:81205999@public.domain.com</a> SIP/2.0</div><div> Via: SIP/2.0/UDP PUBLIC-IP:5070;rport;branch=z9hG4bK4rSU85e8rjj6j</div><div> Max-Forwards: 70</div><div> From: "UserA" <sip:16910067@PUBLIC-IP>;tag=BSNjv3XNrFU1m</div><div> To: <<a href="mailto:sip%3A81205999@public.domain.com">sip:81205999@public.domain.com</a>></div><div> Call-ID: 8fe2118a-fe89-1233-2781-069be24d4191</div><div> CSeq: 83037069 INVITE</div><div> Contact: <sip:gw+pcall@PUBLIC-IP:5070;transport=udp;gw=pvcall></div><div> User-Agent: FreeSWITCH-mod_sofia/1.4.23+git~20151023T152155Z~9fcf3e0c9a~64bit</div><div> Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY</div><div> Supported: timer, path, replaces</div><div> Allow-Events: talk, hold, conference, refer</div><div> Content-Type: application/sdp</div><div> Content-Disposition: session</div><div> Content-Length: 303</div><div> X-FS-Support: update_display,send_info</div><div> Remote-Party-ID: "UserA" <sip:16910067@PUBLIC-IP>;party=calling;screen=yes;privacy=off</div><div><br></div><div> v=0</div><div> o=FreeSWITCH 1446729346 1446729347 IN IP4 PUBLIC-IP</div><div> s=FreeSWITCH</div><div> c=IN IP4 PUBLIC-IP</div><div> t=0 0</div><div> m=audio 16920 RTP/AVP 102 0 8 9 101 13</div><div> a=rtpmap:102 SPEEX/16000</div><div> a=rtpmap:0 PCMU/8000</div><div> a=rtpmap:8 PCMA/8000</div><div> a=rtpmap:9 G722/8000</div><div> a=rtpmap:101 telephone-event/8000</div><div> a=fmtp:101 0-16</div><div> a=ptime:20</div><div><br></div><div> ---------------------------------- 200 OK -------From GW to FS----------------------------</div><div> SIP/2.0 200 OK</div><div> Via: SIP/2.0/UDP PUBLIC-IP:5070;received=PUBLIC-IP;rport=5070;branch=z9hG4bK4rSU85e8rjj6j</div><div> To: <<a href="mailto:sip%3A81205999@public.domain.com">sip:81205999@public.domain.com</a>>;tag=shv30apv2f</div><div> From: "UserA" <sip:16910067@PUBLIC-IP>;tag=BSNjv3XNrFU1m</div><div> Call-ID: 8fe2118a-fe89-1233-2781-069be24d4191</div><div> CSeq: 83037069 INVITE</div><div> Contact: <sip:k471p745@v3n0qcki9ah1.invalid;alias=182.178.237.31~20760~6;transport=ws></div><div> X-Can-Renegotiate: true</div><div> Supported: ice,replaces,outbound</div><div> Content-Type: application/sdp</div><div> Content-Length: 597</div><div><br></div><div> v=0</div><div> o=- 464531514895581299 2 IN IP4 PUBLIC-IP</div><div> s=-</div><div> t=0 0</div><div> a=msid-semantic: WMS QT4IzXsqqeNv2uaXsBBrmLBlUeHKFOYKSRMh</div><div> m=audio 33416 RTP/AVP 0 8 9 101 13</div><div> c=IN IP4 PUBLIC-IP</div><div> a=rtpmap:0 PCMU/8000</div><div> a=rtpmap:8 PCMA/8000</div><div> a=rtpmap:9 G722/8000</div><div> a=rtpmap:101 telephone-event/8000</div><div> a=rtpmap:13 CN/8000</div><div> a=ssrc:4081787962 cname:HWxDJwiTLUiGrbg/</div><div> a=ssrc:4081787962 msid:QT4IzXsqqeNv2uaXsBBrmLBlUeHKFOYKSRMh 3f289eda-ce8d-4219-ac04-1147e6a14fdb</div><div> a=ssrc:4081787962 mslabel:QT4IzXsqqeNv2uaXsBBrmLBlUeHKFOYKSRMh</div><div> a=ssrc:4081787962 label:3f289eda-ce8d-4219-ac04-1147e6a14fdb</div><div> a=sendrecv</div><div> a=rtcp:33417</div></div><div><br></div><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><font face="'times new roman', serif">Regards</font></div><div dir="ltr"><span style="font-family:'times new roman',serif">Salman</span><div><div><pre cols="72"><font face="'times new roman', serif"><br></font><br></pre></div></div></div></div></div></div>
