AW: [Users] Declined INVITE invokes multiple Decline's at Proxy

by Augustin, Andrew (external)

Hello Daniel, Thank you very much for your tips. You are right. The ACK did not match the dialog - under this particular scenario there was an inconsistency between the branch, to, and from tags. Hello All, I have further questions related to this topic and routing of 'locally generated' ACKs... - How does OpenSER distinguish between 'locally generated' and 'end-to-end' ACKs? - How does OpenSER know when a 'locally generated' ACK closes the transaction (e.g. Decline reply) that it is involved in? - Does openser allow the modification of the Route header in a 'locally generated' ACK and usage of TM's t_relay method to relay this ACK? Or is this prohibited so that only OpenSER is allowed to automatically route locally generated ACKs? Best regards, Andrew -----Ursprüngliche Nachricht----- Von: Daniel-Constantin Mierla [mailto:daniel@voice-system.ro] Gesendet: Mittwoch, 12. Juli 2006 16:32 An: Augustin, Andrew (external) Cc: users(a)openser.org Betreff: Re: [Users] Declined INVITE invokes multiple Decline's at Proxy Hello, seems that the ACK does not match the dialog, thus the decline reply is retransmitted. The network trace (ngrep) will help to spot more. Which of Proxy-1..3 is OpenSER and how the INVITE is routed? looking at the reply path, A seems to talk directly with proxy 2, but it is not right since the decline reply is sent back to A from Porxy 1. Or you didn't presented the full trace?

[Serusers] Backup route from SER to GW

by Anders Hansson

Hi, How do I create a backup route using failure_route for sending the transaction to second GW it the main GW is not responding in time. I use this in my ser.cfg and also timers if course... route { ... log("Call to PSTN"); t_on_failure("1"); rewritehost("main GW"); t_relay(); break; }; failure_route[1] { log("<<<<<<<<<< Main SVI is busy or down! Trying secondary SVI! >>>>>>>>>>\n"); rewritehosport("second GW:5060"); append_branch(); t_relay(); break; } And I guess this is OK. But my GW try to send this to internal IP adresses (192.168.x.x) that SER feeds my GW with (I guess). Is it possible to "remove" this IP adresses so that just ip of sec. GW is sent in record_route and Via:? Any other solution how to solve this...? Thanks, Anders

Hello, We 'd like to use openser with radius authentication, accounting We have installed openser from debian package on an ubuntu system: deb http://www.openser.org/debian sarge main But radius authentication failed, and we need avp_radius module too, wich is not included in this package i guess error message in the log: ERROR:auth_radius:radius_authorize_sterman: rc_auth failed on http://openser.org/docs/openser-radius-1.0.x.html i ve 'read that openser should be compiled (with some macros defined in makefile) to work with radius. Is there any possibility to install some deb packages instead of compilation? Which package should we install? Thanks, Tamas

[Users] Rtpproxy question

by Kenny Chua

Hi all, Just a quick question. When I use rtpproxy or mediaproxy, does the media stream actually transfer through my rtpproxy server? Or does media transfers from UA to UA. For example, both UA1 and UA2 are behind different NAT, when the call is connected, does the media travels through the RTPproxy server? Or does it goes directly from UA1 to UA2? Thank you for answering my question. --------------------------------- Do you Yahoo!? Next-gen email? Have it all with the all-new Yahoo! Mail Beta.

[Users] UAC behavior, specifically uac_replace_from

by TSS Support

Okay, I'm trying to use uac_replace_from to anonymize the From: in order to suppress ANI. I think I've got it, but it seems like the behavior isn't what I expect. First, the relevent config file section: if (search("Anonymous")) { uac_replace_from("","sip:anonymous@xxxxxxx.com"); append_rpid_hf("",";party=calling;id-type=subscriber;screen=yes;privacy=full"); log(1,"Made a call anon"); }; Now, the headers as they go in and come out: SIP MESSAGE 4 xx.7.96.185:5061() -> xx.7.96.82:5060() UDP Frame 4 30/Jun/06 08:30:57.4723 TimeFromPreviousSipFrame=0.0069 TimeFromStart=0.0204 INVITE sip:1360789xxxx@voip02.xxxxxxx.com SIP/2.0 Via: SIP/2.0/UDP xx.7.96.185:5061;branch=z9hG4bK-7fa6fcd6;rport From: Anonymous <sip:+136091xxxxxx@voip02.xxxxxxxx.com>;tag=8c07328919ade13ao1 To: <sip:1360789xxxx@voip02.xxxxxxxx.com> Call-ID: 51835bf5-ba1be6be@localhost CSeq: 102 INVITE Max-Forwards: 70 Contact: Anonymous <sip:+136091xxxxx@xx.7.96.185:5061> Expires: 240 User-Agent: Sipura/SPA2000-3.1.5 Content-Length: 311 Allow: ACK, BYE, CANCEL, INFO, INVITE, NOTIFY, OPTIONS, REFER Supported: x-sipura Content-Type: application/sdp SIP MESSAGE 6 xx.7.96.82:5060() -> xx.7.96.90:5060() UDP Frame 6 30/Jun/06 08:30:57.4791 TimeFromPreviousSipFrame=0.0007 TimeFromStart=0.0272 INVITE sip:360789xxxx@xx.7.96.90:5060 SIP/2.0 Record-Route: <sip:xx.7.96.82;ftag=8c07328919ade13ao1;lr=on> Via: SIP/2.0/UDP xx.7.96.82;branch=z9hG4bKe9d1.8c515a97.0 Via: SIP/2.0/UDP xx.7.96.185:5061;branch=z9hG4bK-7fa6fcd6;rport=5061 From: Anonymous <sip:36091xxxxx@voip02.xxxxxxxx.com>;tag=8c07328919ade13ao1 sip:anonymous@xxxxxxxx.com To: <sip:360789xxxx@xx.7.96.90:5060> Call-ID: 51835bf5-ba1be6be@localhost CSeq: 102 INVITE Max-Forwards: 69 Contact: Anonymous <sip:+136091xxxxx@xx.7.96.185:5061> Expires: 240 User-Agent: Sipura/SPA2000-3.1.5 Content-Length: 311 Allow: ACK, BYE, CANCEL, INFO, INVITE, NOTIFY, OPTIONS, REFER Supported: x-sipura Content-Type: application/sdp Remote-Party-ID: "xxxxxxxx Customer" <sip:+136091xxxxx@xxxxxxxx.com>;party=calling;id-type=subscriber;screen=yes;privacy=full And finally what I'm seeing in the log: Jun 30 08:18:33 voip02 /usr/sbin/openser[4684]: DEBUG:uac:replace_from: removing display [Anonymous] Jun 30 08:18:33 voip02 /usr/sbin/openser[4684]: DEBUG:uac:replace_from: uri to replace [sip:+136091xxxxx@voip02.xxxxxxxx.com] Jun 30 08:18:33 voip02 /usr/sbin/openser[4684]: DEBUG:uac:replace_from: replacement uri is [sip:anonymous@xxxxxxxx.com] So what am I missing here? It looks like uac_replace_from is finding the right URI and replacing it, just not properly. I've already gone into CVS and I don't see any changes since 1.0.1 (which is what is running here), nor any relevent changes from SER compared to OpenSER. Any help? Please? -Keith

[Users] Please help for Openser-1.1.0

by Ferianto siregar

Dear all, First of all I would like to say thanks to all the developer team who has released new packet for openser. It is openser-1.1.0. As all of you know that before, I have a problem when I compiled the openser packet with TLS (openser-1.0.1-tls_src.tar.gz).Error in SSL_CTX_set_options. I can`t repair it untill now. But, using openser-1.1.0-tls_src.tar.gz, I don`t have any error message again when I compile TLS by using "make TLS=1 all" command. So, I am very happy that the new openser packet has been released. But, I have some question about the new released. 1. I use the Redhat 9 with the version of kernel is 2.4, can my system that i will build working as well as possible? As I know that the new packet just support operating system debian (all the packet is for debian). or Should i move to Debian? 2. When I try to build database and I run #/usr/local/sbin/openser_mysql.sh, I got error message. So, I look into the directory of /usr/local/sbin, and I don`t find the "openser_mysql.sh". I just find : "openser, openserctl, openserunix". But in openser1.0.1-tls, I can find "openser , openserctl, openser_gen_ha, openser_mysql.sh, openser_postgresql.sh, openserunix". How it can be? Can I copy the "openser_gen_ha, openser_mysql.sh, openser_postgresql.sh" from openser-1.0.1-tls_src to openser-1.1.0 that I have ? So i can bulid the database. or maybe I will get error? Please help me...Please.. Thanks for all regards, Ferianto --------------------------------- How low will we go? Check out Yahoo! Messengers low PC-to-Phone call rates.

[Users] Disconnect Cause on OpenSER

by Hamid Ali Asgari

Hi, I am having a problem with OpenSER and certain types of CPEs. The problem is that the calls get established and the parties can talk, however after a very short period the call gets disconnected. Any guidelines how I could troubleshoot this? PS: Is there anyway to see the calls disconnect cause on OpenSER? I am currently running OpenSER with radius. Thanks in advance, Hamid
