[Users] Unconditional Call Forward help...
by Geir O. Jensen 24 Apr '07

24 Apr '07

I need CFU on our systems, however - it seems to work but if the forwarded call isn't picked up within a time limit the system just drops the call. My script is something like this; (...) loadmodule "tm.so" modparam ("tm", "fr_timer", 30) modparam ("tm", "fr_inv_timer", 10) route{ xlog("L_INFO", "Route - $fu $rm $ru"); t_on_failure("1"); (... Some tweaking ...) t_relay(); } failure_route[1] { if (!t_was_cancelled()) { xlog("L_INFO","Failure_route[1] - redirect to callcentre"); seturi("sip:callcentre@localhost"); append_branch(); t_relay(); }; return; } So what happens is this; I call a number... After 10 seconds the call "fails" and failure_route is invoked, whereupon the call is "redirected" to the new uri. It rings for 10 seconds and then the the call is just terminated... (no call to failure_route)... The log looks like this; 15:30:00 Route sip:usera@localhost INVITE sip:userb@localhost 15:30:10 Failure_route[1] - redirect to callcentre 15:30:20 Route sip:usera@localhost ACK sip:userb@localhost Any ideas? Typically I would like for the 2dn call to ring indefinitely... // sip:gojensen@uninett.no | h323: 004710012 pstn: +47 73 55 79 23 | fax: +47 73 55 79 01

Hi, Can anybody send a sample config of ser.cfg for inbound routes which will be coming from asterisk server? UA1------->Asterisk----------->SER-------->UA2. Outbound is working perfectly. Thank you very much. Bengie888 --------------------------------- Ahhh...imagining that irresistible "new car" smell? Check outnew cars at Yahoo! Autos.

[Users] rtpproxy - ICMP unreacheable host- FINALLY SOLVED
by Amanda Mattiuz 24 Apr '07

24 Apr '07

Hi! I'd like to thank all for the help!! I solved my problem... in fact the problem was that my server had this firewall running in another machine and I was not aware of that, so I was checking my IP tables and everything seem to be opened, but in fact it was not. That's the reason for the "unreacheable destination". The unreacheable destination was, in fact, the server machine itself where I have also rtpproxy running.... the cfg file and everything is OK. Thansk again for the help!

[Users] FIFO chmod
by Joao Pereira 24 Apr '07

24 Apr '07

Hello My serweb needs the FIFO to be with writing permissions: prwxrwxrwx 1 root root 0 Apr 23 23:23 /tmp/openser_fifo But every time I reload Openser, the openser_fifo permissions dont allow serweb to use the FIFO. In the old SER I did: fifo_mode=0666 But this doesn't work in OpenSER Is there any similar command in Openser? Thanks Regards Joao Pereira

[Users] ACC module, always prints message for successful transaction
by Tim Madorma 24 Apr '07

24 Apr '07

Hi, I would rather not have a syslog message for successful transactions - just failed ones. I have set the appropriate flags for the transactions that I would like to see: my settings are: modparam("acc", "log_level", 2) modparam("acc", "log_flag", 1) modparam("acc","report_cancels", 1) modparam("acc","failed_transaction_flag", 1) But in my syslog, I get a log entry for every successful transaction - such as: Apr 23 13:54:12 homer openser[17280]: [ID 729047 local0.notice] ACC: transaction answered: timestamp=1177350852;method=INVITE;from_t ag=188229;to_tag=6110;call_id=188229-14338(a)65.185.233.183;code=200;reason=OK How do I stop ACC from logging for successful transactions? thanks, Tim

[Serusers] SER + RTPproxy with video
by roayu 24 Apr '07

24 Apr '07

Good day! I'm a newbie on SER. I had configured a SER server running with RTPproxy. I'm using SER v0.9.6 and RTPproxy Basic Version 20040107. It works fine with the audio but not for the video. From what i understand that this version of rtpproxy do support both audio and video. I had trace the message header of SDP and it seems fine. I'm not sure what caused this happended. Could you pls guide me on this? Thanks. Regards, Roa

[Serusers] Mediaproxy sip-asymmetric-clients
by Ali Zaidi 23 Apr '07

23 Apr '07

Hi, I have been using ser with mediaproxy for more than a year without any major issue. I have couple of asymmetric UAs, and i'm not able to call them most of the time. i noticed in my ser.cfg following lines. My ser.cfg =========================== modparam("mediaproxy","sip_asymmetrics","/usr/local/etc/ser/sip-clients") modparam("mediaproxy","rtp_asymmetrics","/usr/local/etc/ser/rtp-clients") # modparam("mediaproxy","sip_asymmetrics","/usr/local/etc/ser/sip-asymmetric-clients") # modparam("mediaproxy","rtp_asymmetrics","/usr/local/etc/ser/rtp-asymmetric-clients") =========================== I have above files in ser folder, and i tried to put user agent in sip-clients file, i don't know if i'm doing it right. Ii'm still trying to figure it out, what should i put in these sip-clients and rtp-clients files (username? URI ), and how do i know if they are working. I just put UA 5007860215 and restarted ser and mediaproxy but ngrep are same. my sip-clients file is as follows: ########### START ################## # Lines starting with a '#' character or empty lines are ignored. # Put a User-Agent name or regular expression per line. # Check is case insensitive. # # This file should only list SIP clients that are asymmetric regarding # the SIP signaling. For clients that are asymmetric regarding the RTP # media streams, use the equivalent RTP version of this file. # Clients that are asymmetric for both SIP signaling as well as RTP media # streams should go in both files. # ipDialog SipTone.* #<== what is it? 5007860215 ########### END OF FILE############ client sending keep alive message, reason i setup keep alive on my client is becouse they were keep loosing registration, so that problem is solved.

[Users] MediaProxy Scenario
by Edson 23 Apr '07

23 Apr '07

Hi... I have two questions (well, three): 1a) How should Mediaproxy be configured so to permit a call interruption? 1b) Is there any external interface that permit communications with the Mediaproxy process? 2) How can a call (RTP traffic) be recorded with MediaProxy? Any format... Edson. ------ "It wouldn't be sell if it were easy..."
