That's right but the difference is that the second invite reply (from Sipura) arrives to the server and the first one from Thomson don't. > You have an issue because NAT.

Thank you for this hint. It reminded me a wonderful option in openser core called "advertised_address" where you can set what you want to see in the first Via. So I set my domain name there. It is resolved with the public IP from outside and with the lan IP from the inside and now it works from both sides ! -- Regards, - vma .

Guys, thanks to your support (both Bogdan and Daniel), I found out that there was nothing wrong with the server and t_onreply handling, but the INVITE was taking another routing three than the one I was checking and therefore never hit the t_on_reply section I wanted. This being said, I consider this issue resolved. Cheers, Dan

Looks you have SIP ALG enabled on your NAT, which breaks the call transfer (no surprise, I haven't seen working SIP ALG yet). Check OPTIONS request sent by SJphone and received by SER, check NOTIFY sent by SJphone and received by SER. Disable the SIP ALG and try again. If you can't disable it, change the NAT box itself.

[OpenSER-Users] Strange behavior for openser 1.3 in mhomed mode (automatic mangling of Contact header and c= line of SDP)
by Ovidiu Sas 19 Oct '07

19 Oct '07

Hi all, I was playing with openser 1.3 in a multihomed setup. In this setup, I noticed that by default, openser is mangling the Contact header and the sdp. I stripped down the config to bare minimum to see if it was something related to my config, but it seems that this is not related to the config. Here's the stripped down config that I used: # ----------- global configuration parameters ------------------------ debug=3 fork=yes log_stderror=no check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) auto_aliases=no listen=udp:br0 listen=udp:eth1 children=1 mhomed=1 disable_tcp=yes disable_dns_blacklist=true # ------------------ module loading ---------------------------------- mpath="/opt/lib/openser/modules" loadmodule "sl.so" loadmodule "tm.so" # -- tm params -- modparam("tm", "fr_inv_timer", 100) modparam("tm", "fr_inv_timer_avp", "$avp(i:26)") modparam("tm", "fr_timer", 10) modparam("tm", "fr_timer_avp", "$avp(i:25)") modparam("tm", "noisy_ctimer", 1) modparam("tm", "onreply_avp_mode", 1) loadmodule "rr.so" # ------------------------- request routing logic ------------------- # main routing logic route{ if (!method=="REGISTER") { record_route(); } if (loose_route()) { route(1); }; if (!uri==myself) { route(1); }; if (uri==myself) { sl_send_reply("404", "Not Found"); exit; }; route(1); } route[1] { if (!t_relay()) { sl_reply_error(); }; exit; } Here's the network setup: <asterisk box> --- < openser > --- <SIP server> <192.168.2.20> --- <192.168.2.1 : EXTERNAL_IP> --- <SIP_SERVER> And here's an ngrep of the initial INVITEs: 23:53:31.439678 IP 192.168.2.20.sip > 192.168.2.1.sip: SIP, length: 819 INVITE sip:callee@SIP_SERVER SIP/2.0 Via: SIP/2.0/UDP 192.168.2.20:5060;branch=z9hG4bK4f70ea70 From: "Ovi Sas" <sip:caller@SIP_SERVER>;tag=as048c5bed To: <sip:callee@SIP_SERVER> Contact: <sip:caller@192.168.2.20> Call-ID: 28aedce563bc57dc2cac78967e69c141@SIP_SERVER CSeq: 102 INVITE User-Agent: asterisk Max-Forwards: 70 Date: Thu, 18 Oct 2007 04:23:04 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Content-Type: application/sdp Content-Length: 285 v=0 o=root 8560 8560 IN IP4 192.168.2.20 s=session c=IN IP4 192.168.2.20 t=0 0 m=audio 34028 RTP/AVP 0 3 8 101 a=rtpmap:0 PCMU/8000 a=rtpmap:3 GSM/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=sendrecv 23:53:31.454727 IP EXTERNAL_IP.sip > SIP_SERVER.sip: SIP, length: 1011 INVITE sip:callee@SIP_SERVER SIP/2.0 Record-Route: <sip:EXTERNAL_IP;r2=on;lr;ftag=as048c5bed> Record-Route: <sip:192.168.2.1;r2=on;lr;ftag=as048c5bed> Via: SIP/2.0/UDP EXTERNAL_IP:5060;branch=z9hG4bKea4e.7aacc885.0 Via: SIP/2.0/UDP 192.168.2.20:5060;branch=z9hG4bK4f70ea70 From: "Ovi Sas" <sip:caller@SIP_SERVER>;tag=as048c5bed To: <sip:callee@SIP_SERVER> Contact: <sip:caller@EXTERNAL_IP:5060> Call-ID: 28aedce563bc57dc2cac78967e69c141@SIP_SERVER CSeq: 102 INVITE User-Agent: asterisk Max-Forwards: 70 Date: Thu, 18 Oct 2007 04:23:04 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Content-Type: application/sdp Content-Length: 286 v=0 o=root 8560 8560 IN IP4 192.168.2.20 s=session c=IN IP4 EXTERNAL_IP t=0 0 m=audio 34028 RTP/AVP 0 3 8 101 a=rtpmap:0 PCMU/8000 a=rtpmap:3 GSM/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=sendrecv Please note the Contact header and the c= line inside SDP. Is there a way to bypass this behaviour? Using the nathelper module doesn't seem to help (the Contact header will still carry the EXTERNAL_IP. Regards, Ovidiu Sas

[OpenSER-Users] Problem with python-application when installing OpenXCAP

Hello, I try to install OpenXCAP on a Ubuntu server Feisty machine. I am up to the point of installing the python-application 1.0.9, but when I try to install it with python setup.py install, I get the following error : byte-compiling /usr/lib/python2.5/site-packages/application/python/queue.py to queue.pyc File "/usr/lib/python2.5/site-packages/application/python/queue.py", line 9 v v v v v v v ^ SyntaxError: invalid syntax As I have absolutely no experience with Python, I would like to know how I could work around this error. Thank you in advance for your help, Antoine
