[Serusers] Help: mediaproxy error? or domain issue?
by Charles Wang 14 Mar '05

14 Mar '05

Dear ALL: I install my SER on two machines, one named "SER_A" and the other named "SER_B". Two UACs register to each server. One named "UAC_A" the other named "UAC_B". Server Domain Prefix UAC UAC's ID ------------------------------------------------------------------------- SER_A A.com 852 UAC_A 1011 SER_B B.com 886 UAC_B 2022 ------------------------------------------------------------------------- Prefix_Domain table: --------------------------------- domain | prefix ----------------|----------------- A.com | 852 B.com | 886 ----------------|----------------- My senario is below: UAC_A ======> SER_A ====> SER_B ====> UAC_B 1011 || || 2022 (dial a number || || (Ringing) 8862022) || Accept 2022(a)B.com || and forward to UAC_B change 8862022(a)A.com to 2022(a)B.com I install SER+MediaProxy on my systems and using pdt modules to do the prefix convert. I find these error behaviors on my SER_A's log file. And the call from 1011 to 2022. The call seems be process twice. You can find "Prefix To Domain Checking" twice at the beginning. Can anybody give me some tips to solve it? ---------------------- My log file ----------------------------------------------- ser /usr/local/sbin/ser[23458]: SER: Prefix To Domain Checking... ser /usr/local/sbin/ser[23458]: SER: SIP Call On-Net section route(2) ser /usr/local/sbin/ser[23456]: SER: Prefix To Domain Checking... ser /usr/local/sbin/ser[23456]: SER: SIP Call On-Net section route(2) ser proxydispatcher[23541]: command request D24BF98F-101E-43F4-9765-4DBB863A999D(a)192.168.11.5 192.168.11.5:8000:audio xxx.xxx.133.108 A.com local B.com remote X-PRO=20build=201082 info=from:1011@A.com,to:8862022@A.com,fromtag:3667188260,totag: ser /usr/local/sbin/ser[23463]: SER: Prefix To Domain Checking... ser /usr/local/sbin/ser[23463]: SER: SIP Call On-Net section route(2) ser proxydispatcher[23542]: command request D24BF98F-101E-43F4-9765-4DBB863A999D(a)192.168.11.5 192.168.11.5:8000:audio xxx.xxx.133.108 A.com local B.com remote X-PRO=20build=201082 info=from:1011@A.com,to:8862022@A.com,fromtag:3667188260,totag: ser proxydispatcher[23541]: domain A.com doesn't define any mediaproxy. ser proxydispatcher[23541]: will use default mediaproxy for this call. ser mediaproxy[18756]: command request D24BF98F-101E-43F4-9765-4DBB863A999D(a)192.168.11.5 192.168.11.5:8000:audio xxx.xxx.133.108 A.com local B.com remote X-PRO=20build=201082 info=from:1011@A.com,to:8862022@A.com,fromtag:3667188260,totag:,dispatcher ser mediaproxy[18756]: session D24BF98F-101E-43F4-9765-4DBB863A999D(a)192.168.11.5: started. listening on xxx.xxx.190.248:35020 ser mediaproxy[18756]: command execution time: 10.30 ms ser proxydispatcher[23541]: forwarding to mediaproxy on /var/run/mediaproxy.sock: got: 'xxx.xxx.190.248 35020' ser proxydispatcher[23541]: command execution time: 3365.77 ms ser proxydispatcher[23542]: domain A.com doesn't define any mediaproxy. ser proxydispatcher[23542]: will use default mediaproxy for this call. ser mediaproxy[18756]: command request D24BF98F-101E-43F4-9765-4DBB863A999D(a)192.168.11.5 192.168.11.5:8000:audio xxx.xxx.133.108 A.com local B.com remote X-PRO=20build=201082 info=from:1011@A.com,to:8862022@A.com,fromtag:3667188260,totag:,dispatcher ser mediaproxy[18756]: command execution time: 0.39 ms ser proxydispatcher[23542]: forwarding to mediaproxy on /var/run/mediaproxy.sock: got: 'xxx.xxx.190.248 35020' ser proxydispatcher[23542]: command execution time: 4101.53 ms ser /usr/local/sbin/ser[23463]: SER: Failure Route section failure_route(1) ser /usr/local/sbin/ser[23456]: SER: Prefix To Domain Checking... ser /usr/local/sbin/ser[23456]: SER: SIP Call On-Net section route(2) --------------------- My ser.cfg ----------------------------------------------------------- #

Hi Jan, Thank you for your reply and sorry for coming back so late on the subject. Below is some output from SER and the backtrace that I obtained with gdb.

[Serusers] PA Module Query
by Aisling O'Driscoll 14 Mar '05

14 Mar '05

Hi everyone, >From what Ive seen in the archives, the latest unstable version of ser is needed to support presence (i.e. the pa module),is that correct?? I am currently running 8.0.14....If this is the case,could someone let me know how I use cvs to get the latest unstable and if I do get this version will it overwrite my current ser config?? Also does windows messenger 5 work with the pa module or should I just not bother and use a different client?

Please always send the emails to the mailinglist. Typically, RTP goes directly between the user agent, not via the proxy. Only in certain situations the rtpproxy is necessary (user is behind symmetric NAT) In must situations, the NAT problem can be solved by using STUN and rtpproxy is not necessary. Nevertheless a rtpproxy is necessary in certain situations and therefore (as traffic matters) it makes sense to use multiple rtpproxys. regards, Klaus > > Thanks > Barry > ----- Original Message ----- > From: "Klaus Darilion" <klaus.mailinglists(a)pernau.at> > To: "Barry Murphy" <barry(a)unix.co.nz> > Cc: "Alistair Cunningham" <acunningham(a)integrics.com>; <serusers(a)lists.iptel.org> > Sent: Friday, March 11, 2005 9:17 PM > Subject: Re: [Serusers] Voip Solution advice > > > >>Hi Barry! >> >>A one server setup is simple.

[Serusers] how to add a header into the reply??
by szj 14 Mar '05

14 Mar '05

I want to add some extra header to the positive responce. I don't want to attain that in script, instead I want to do that in the code or another module. What I did is to add the following into the reply_received function. if((t->flags & T_IS_INVITE_FLAG) && (!is_local(t)) && (msg_status >=200 && msg_status <300)) { typedef int(*local_fp)(struct sip_msg *msg, char *txt, int flags); local_fp append_to_reply = NULL; append_to_reply = (local_fp)find_export("append_to_reply", 1, 0); if(append_to_reply){ DBG("DEBUG: SUNZJ find apppend_to_reply\n"); append_to_reply(p_msg, "P-Security-Nobody: this is a test header for \r\n", 0); } } But it doesn't seem to work for me. I can't see the added text from my SIP UA log. How could I get to that?? Thanks for your instructions! Best Regards Sun Zongjun
