Guys, I would need your help in troubleshooting some pretty serious issue for me. Scenario: relaying an INVITE from openser to a softswitch and recognizing the flags (global and branch ones) in onreply. Everything seems to work fine with relaying the requests, but when the answers are matched in onreply, the flags are gone. Bellow is the log configuration which gives the output used by me to troubleshoot in logs: in route: xlog("First branch: $br, all branches: $bR, flags set: $mf , branch flags: $bf"); xlog("Relaying to: $avp(s:route), message: $mb"); xlog("OUT to Softswitch"); in onreply route: xlog ("ENTERING ON REPLY ROUTE"); xlog("First branch: $br, all branches: $bR, flags set: $mf , branch flags: $bf"); xlog("In onreply, message: $mb"); Please see the output bellow: Dec 20 10:07:51 ellie /usr/local/sbin/openser[15295]: First branch: <null>, all branches: <null>, flags set: 130 , branch flags: 1024 Dec 20 10:07:51 ellie /usr/local/sbin/openser[15295]: Relaying to: pstn1, message: INVITE sip:INT_NUMBER_MASKED@sip.itsyscom.com SIP/2.0^M Via: SIP/2.0/UDP 10.10.11.10:7091;rport;branch=z9hG4bK2127028508^M From: <sip:dan@sip.itsyscom.com>;tag=2128765320^M To: <sip:INT_NUMBER_MASKED@sip.itsyscom.com>^M Call-ID: 886593274(a)10.10.11.10^M CSeq: 21 INVITE^M Contact: <sip:dan@10.10.11.10:7091>^M Proxy-Authorization: Digest username="dan", realm="sip.itsyscom.com", nonce="476a40226a7cfaa9a11de5b6e7d6742d45ec6bd4", uri="sip:INT_NUMBER_MASKED@sip.itsyscom.com", response="08872e4a06f011ea7d6f947f1874a882", algorithm=MD5^M Max-Forwards: 4^M User-Agent: Linphone-1.5.1/eXosip^M Subject: Phone call^M Expires: 120^M Allow: INVITE, ACK, CANCEL, BYE, OPTIONS, REFER, SUBSCRIBE, NOTIFY, MESSAGE^M Content-Type: application/sdp^M Content-Length: 310^M ^M v=0^M o=dan 123456 654321 IN IP4 10.10.11.10^M s=A conversation^M c=IN IP4 10.10.11.10^M t=0 0^M m=audio 7078 RTP/AVP 3 0 8 111 110 101^M a=rtpmap:3 GSM/8000/1^M a=rtpmap:0 PCMU/8000/1^M a=rtp Dec 20 10:07:51 ellie /usr/local/sbin/openser[15295]: OUT to Softswitch Dec 20 10:07:51 ellie /usr/local/sbin/openser[15295]: ENTERING ON REPLY ROUTE Dec 20 10:07:51 ellie /usr/local/sbin/openser[15295]: First branch: <null>, all branches: <null>, flags set: 0 , branch flags: 0 Dec 20 10:07:51 ellie /usr/local/sbin/openser[15295]: In onreply, message: SIP/2.0 100 Trying^M Via: SIP/2.0/UDP IP_MASKED;branch=z9hG4bK9221.886b3817.0;received=IP_MASKED;rport=5060^M Via: SIP/2.0/UDP 10.10.11.10:7091;received=ORIGINATOR_IP;rport=8026;branch=z9hG4bK2127028508^M Record-Route: <sip:IP_MASKED;lr=on;ftag=2128765320;nat=yes>^M From: <sip:dan@sip.itsyscom.com>;tag=2128765320^M To: <sip:INT_NUMBER_MASKED@sip.itsyscom.com>^M Call-ID: 886593274(a)10.10.11.10^M CSeq: 21 INVITE^M Server: GlobalE SoftSWITCH/1.3.0.^M Content-Length: 0^M ^M Dec 20 10:07:53 ellie /usr/local/sbin/openser[15296]: ENTERING ON REPLY ROUTE Dec 20 10:07:53 ellie /usr/local/sbin/openser[15296]: First branch: <null>, all branches: <null>, flags set: 0 , branch flags: 0 Dec 20 10:07:53 ellie /usr/local/sbin/openser[15296]: In onreply, message: SIP/2.0 180 Ringing^M Via: SIP/2.0/UDP IP_MASKED;branch=z9hG4bK9221.886b3817.0;received=IP_MASKED;rport=5060^M Via: SIP/2.0/UDP 10.10.11.10:7091;received=ORIGINATOR_IP;rport=8026;branch=z9hG4bK2127028508^M Record-Route: <sip:IP_MASKED;lr=on;ftag=2128765320;nat=yes>^M From: <sip:dan@sip.itsyscom.com>;tag=2128765320^M To: <sip:INT_NUMBER_MASKED@sip.itsyscom.com>;tag=975999519^M Call-ID: 886593274(a)10.10.11.10^M CSeq: 21 INVITE^M Server: GlobalE SoftSWITCH/1.3.0.^M Contact: <sip:INT_NUMBER_MASKED@IP_MASKED:5070>^M Allow: ACK, INVITE, BYE, CANCEL, OPTIONS^M Content-Type: application/sdp^M Content-Length: 187^M ^M v=0^M o=yate 1198145273 1198145273 IN IP4 208.50.127.243^M s=SIP Call^M c=IN IP4 208.50.127.243^M t=0 0^M m=audio 23166 RTP/AVP 8 101^M a=rtpmap:8 PCMA/8000^M a=rtpmap:101 telephone-event/8000^M Can any of you help me troubleshooting this?
