[OpenSER-Users] OpenSER SST module for session timer

by Pat wang

Happy holidays! Not sure what happened to my previous email the format is kind of messy. Sorry about that. I am playing with SST module for session timer and have some questions that I would like someone can help me out. 1. First question is the 422 message is not sent immediately after receiving INVITE with SE header smaller than default 1800 sec. My OpenSER script is very strait forward as the example in the module document: if (method=="INVITE") { if (sstCheckMin("1")) { blah blah.... exit; } } Debug on OpenSER shows the result returns -1 when an INVITE contains SE and Min-SE timer at 90. It is until the INVITE hits lookup("location") it replies a 422. 2. Right after OpenSER sends a 422 it proxies the INVITE to the called party at that same time. So the call flow looks like: Caller OpenSER Callee INVITE (SE 90)=======> <======= 422 ==== ======INVITE===> === INVITE (SE 1800)==> 3. The 422 Session Timer Too Small message put MIN-SE and Server headers in one line which looks like: MIN-SE: 1800Server: OpenSER........... Has anyone tried SST module before and how did it work for you? Many thanks for you help.

[Serusers] fifo question

by Strassburger, Patrick

Hi all, I am struggling arround since hours about fifo. I get all the time a syntax error. Tired several things like chmod, cr /tmp/ser_fifo as a file or directory, created a /temp/ser_fifo. Changed ser.cfg to fifo="/temp/ser_fifo" fifo_mode=0666 with / without "" does not help all the time a syntax error. Can someone explain - what fifo is (file or folder) - would gues it is a file (first in first out)? - does fifo needs to be created before? I changed /temp/ or /tmp/ to 666 but this does not help either. starting ser shows me [root@ser /]# ser -f /etc/ser/ser.cfg -c 0(8574) parse error (23,1-5): syntax error 0(8574) parse error (23,1-5): ERROR: bad config file (2 errors) wherin line 23 is the one with fifo.

[Serusers] Solution for the NAT IP changed?

by Gonzalo J. Sambucaro

Hello folks, I was Working in the NAT IP changed solution, my idea is to change media proxy server (MPS) in a such way when in a established connection and receive a RTP package from unknown IP source (because a NAT server changed their IP), using de field SSRC (RFC 3550 RTP) updates the binding (with the new IP detected) between the caller and the MPS or between the called and the MPS according to the field SSRC previously saved. What do you think about my solution? Regards, Gonzalo Sambucaro. -- Gonzalo J.

[OpenSER-Users] OpenSER 1.2.3 patch release is out!

by Bogdan-Andrei Iancu

Hi everybody, The third patch release of 1.2.x series is out as version 1.2.3. It preserves full compatibility with 1.2 family regarding the configuration file. OpenSER 1.2.3 brings all kind of fixes (mainly from the 1.3 version). No new features were added. The 1.2.3 release includes: - small fixes (compile warnings, porting across UNIX platform errors - bug fixing - mi_xmlrpc update to work with latest 1.0 libxmlrpc-c3 releases - functionality fixes (Route header handling in local sequential requests) - small improvements - more self - sanity checks, more verbose error codes in script (like t_relay() in TM). Tomorrow I will start uploading the tarballs on the web sites. Best regards, Bogdan

[OpenSER-Users] Need help troubleshooting flags in onreply route - v.1.2.2

by Dan-Cristian Bogos

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?
