[Serusers] finding the domain of the Request-URI
by Ricardo Carvalho 13 Sep '06

13 Sep '06

Hi all, Is there a function that returns the domain (the realm) of the Request-URI of INVITE messages? Note that it can't be done using regular expressions that search SIP messages, because of cases where has been dialled an alias of someone from a phone registered with a user that belongs to other domain in a multi-domain environment. Thanks, Ricardo.

[Serusers] XCAP server
by Henry Duan 13 Sep '06

13 Sep '06

Hi there: I want to test the SIP based endpoint. I'm wondering if there is any open-source XCAP server available for testing, or if SER has the XCAP server module? Thanks so much! henry

[Users] Problem with Asterisk - Openser Voicemail integration
by Antoine Fressancourt 13 Sep '06

13 Sep '06

Hello, I am trying to setup a voicemail solution based on the tutorial published on voip-info.org called "Realtime Integration of Asterisk with OpenSER" ( http://www.voip-info.org/wiki/view/Realtime+Integration+Of+Asterisk+With+Op…) and I face an issue. I followed the steps carefully, and I am about to start running the openser server. But when I try to launch the server, two lines are troublesome. My first error is the following : 0(0) ERROR:avpops:fixup_write_avp: bad attribute name in param 2 <i:10> 0(0) ERROR: fix_actions: fixing failed (code=-1) at cfg line 133 It is related to the following line of the openser.cfg : avp_write("$ruri", "i:10"); Then, I comment the line, and another error appears : 0(0) ERROR:avops:fixup_pushto_avp: bad param 1; expected : $pseudo-variable ... 0(0) ERROR: fix_actions: fixing failed (code=-1) at cfg line 200 It is realted to the line : avp_pushto("$ruri", "i:10"); I have the dialplan writen in the tutorial and I run the latest stable version of OpenSER : openser-1.1.0-notls Hopefully someone encontered the same issue, and managed to solve it. Thank you in advance, Antoine

[Users] ReInvite send twice
by Stefan Römer 13 Sep '06

13 Sep '06

Hi !!! I'm using OpenSER 1.0.1 and realized some strange behaviour when SIP UA sends ReInvite Messages. Initial INVITE shown below (this is OK) UA A OpenSER UA B _____________________________________________________________ --------INVITE------------> -----------INVITE------------> <--------200 OK----------- <---------200 OK---------------- ---------ACK-------------> -------------ACK---------------> But when an UA sends a ReINVITE message I realized following behaviour. This happens approximatly every 3rd or 4th ReInvite. UA A OpenSER UA B _____________________________________________________________ --------INVITE------------> -----------INVITE------------> -----------INVITE------------> <--------200 OK----------- <---------200 OK---------------- <--------200 OK----------- <---------200 OK---------------- . . . . Is there any reason for OpenSER sending ReINVTE twice? Any chance to avoid this? Sincerly Stefan

[Users] ACK consume_credentials()??
by Greg Fausak 13 Sep '06

13 Sep '06

In an outbound call I am able to use consume_credentials() to get rid of all Authorization: Digest... lines in the header, except for the ACK. Can I strip the header from the ACK? I can't seem to catch it. -g -- Greg Fausak greg(a)thursday.com

[Users] Siptrace - 200 OK
by Alberto Pacifico 13 Sep '06

13 Sep '06

Hi all, I'm using Openser with siptrace and I'm getting the following sip messages: Invite, Ack, Bye and Cancel. The Openser is recording these messages into sip_trace table (DB openser). I would like to get "200 OK" sip message too. Is it possible?? PS: My openser is working together freeradius and mysql.

[Serusers] fix_nated_contact not rewriting contact?
by kjcsb 13 Sep '06

13 Sep '06

I have the following config: if (client_nat_test("3")) { #IP address in contact is private IP #Via is different to address client has contacted us from #If so then setflag7 to indicate that sender is behind NAT xlog("client nat test 3 returned true for r-uri <$ru> in route 3 so will setflag7"); setflag(7); xlog("contact before update <$ct>"); xlog("via before update <$hdr(via)>"); force_rport(); #Rewrite Contact: header to contain Sip client's public IP:port fix_nated_contact(); xlog("contact is now <$ct>"); xlog("via is now <$hdr(via)>"); }; However the value returned by $ct is the same before and after fix_nated_contact(). Is that because I'm doing something wrong, or because I've misunderstood fix_nated_contact or because the $ct variable doesn't get updated by fix_nated_contact? If the latter, how can I find out the result of fix_nated_contact? The same applies to force_rport and the via details. Any advice appreciated. Regards Cameron

[Users] missing contact header
by Fatih Cerit 13 Sep '06

13 Sep '06

Hi I want to overwrite the contact header field using textops but some UAs send only an asterisk as a contact (like below). Is this defined in protocol (I didn't find) ? I don't decide what to do . Do I reply with an error or use another field (from,to) as contact thanks REGISTER sip:sip.anywhere.com SIP/2.0 Via: SIP/2.0/UDP 10.0.0.49;branch=z9hG4bK8eaa0451724f9bf4 From: "test" <sip:11223344@sip.anywhere.com;user=phone>;tag=9969d7f94927b840 To: <sip:11223344@sip.anywhere.com;user=phone> Contact: * Call-ID: 0c55cf4a80b02370(a)10.0.0.9 CSeq: 100 REGISTER Expires: 0 User-Agent: Grandstream HT286 1.0.5.11 Max-Forwards: 70 Allow: INVITE,ACK,CANCEL,BYE,NOTIFY,REFER,OPTIONS,INFO,SUBSCRIBE Content-Length: 0

[Serusers] SER and CPU usage
by Paco Hsiao 13 Sep '06

13 Sep '06

Hi, All, I am using SER 0.9.6, rtpproxy 0.3 and MySQL 4.1.11. All are running under Fefora Core 4 on one machine. Now, there is a very serious problem that I fork 24 children and each ser's CPU usage is around 15%. Why? I check the count of registered users is only about 600. And the concurrent call is about 20. Why the CPU usage is so large? The idle of CPU is almost 0%. I find the archive that there is a same problem on http://lists.iptel.org/pipermail/serusers/2005-October/024575.html, but he used PGSQL database. Not MySQL DB. Could you help me? Thanks! Regards, Paco
