[Kamailio-Users] DIVERSION or UAC_REDIRECT or BOTH
by Omar Mendoza 03 Sep '09

03 Sep '09

I got confused: Using Kamailio 1.4.3 uac_redirect is been used to handle diversion, also the draft expired there is anew one http://tools.ietf.org/html/draft-levy-sip- diversion-10, is this used together with the diversion module, or no need at all. or is diversion module when you have customers registered in your system? I am do not have phones registered in my system at all, i use mainly the CR module, and i need to allow diversion headers. which one to use, or both?! Also i am scare to use the diversion due the CDRs will create a new record for that, who i will charge the call for?! :) and if i use UAC_REDIRECT should i be able to use the avp $dip and the following, from ROUTE to add to the accounting? Diversion header URI $di - reference to Diversion header URI Diversion "privacy" parameter $dip - reference to Diversion header “privacy” parameter value Diversion "reason" parameter $dir - reference to Diversion header “reason” parameter value __________________________ O the Great

[Kamailio-Users] registrar lookups without reason
by jh＠tutpro.com 02 Sep '09

02 Sep '09

when analyzing the weird problem, where request uri gets rewritten with aor's contact even when there is no command in config file that would do it, i noticed these lines in syslog: Aug 31 16:41:50 /usr/sbin/kamailio[23139]: DBG:core:rewrite_uri: rewriting Request-URI with 'sip:foo.bar@ip-address:5060;transport=UDP' Aug 31 16:41:50 opensipg /usr/sbin/kamailio[23139]: DBG:registrar:lookup: 'foo.bar@ip-address' Not found in usrloc Aug 31 16:41:50 opensipg /usr/sbin/kamailio[23139]: DBG:registrar:lookup: 'foo.bar@ip-address' Not found in usrloc any one has any idea why lookup was called even when it is not in the script? this is getting very weird. looks like kamailio is executing statements on its own. -- juha

[Kamailio-Users] LCR questions ( ping and flags columns )
by Ricardo Martinez 01 Sep '09

01 Sep '09

Hello list. I have a couple of questions about the LCR module. The first one is about the "ping" column in the gw table. I guess this column stores the "results" of execute a ping to the gateways in the LCR.gw table isn't?. So how this "ping" is executed? It is just a simple ICMP message? Or maybe is an OPTIONS sip message to the gateway?. I saw in the lcr_mod.c file some ping_method, ping_interval variables, but in the README file there is nothing about the "ping". Could someone clarify this to me this? Second. In the mysql "gw" table there is a column called "flags". According to the README file it said that this column can store gateways "capabilities". For example, and I hope that someone could guide me here, can i store the maximum channels available per gateway?, and use it to select or not select a gateway according the gateway channels used?. I hope that someone could help me here. Thank in advance, Regards, Ricardo Martinez.-

[Kamailio-Users] rewriteuser( ) with avp
by Alex R.S.M 31 Aug '09

31 Aug '09

Hi, I'm trying to change "username" field of URI in the INT message. When using rewriteuser() function with avp variable as below, the username is changed to $avp(i:8) itself instead of the value of the avp. rewriteuser("$avp(i:8)"); I've tried all sorts of diff formats and none of them replace username with the value of avp variable.: rewriteuser($avp(i:8)); rewriteuser("avp(i:8)"); is this a bug? Thanks, A-RS _________________________________________________________________ Windows Live: Keep your friends up to date with what you do online. http://windowslive.com/Campaign/SocialNetworking?ocid=PID23285::T:WLMTAGL:O…

[Kamailio-Users] scope of AVPs (AVP defined when execution of script starts)
by jh＠tutpro.com 29 Aug '09

29 Aug '09

i have always thought that AVPs exits per transaction. that does not seem to be the case, however, because when i put in the beginning of my script xlog("L_INFO", "Caller lcr_id $avp(CALLER_LCR_ID_AVP)\n"); this gets printed to syslog: Aug 29 11:34:34 localhost /usr/sbin/sip-router[10210]: INFO: Caller lcr_id 2 is this the indented behavior? do i really need to delete all AVPs in the beginning of the script in order to make sure that they don't have any values left from processing of previous message? -- juha

[Kamailio-Users] Phones that support TLS with certificate
by catalina oancea 27 Aug '09

27 Aug '09

Hello, I am trying to find the phones that can use tls with certificate, I mean that the phone doesn't accept incoming calls unless the server certificate is signed by a public authority or manually added to a list. For now my conclusions are: -Snom 360 - works with TLS. But although snom wiki states that a certificate is needed, incoming calls are accepted even if the certificate is not uploaded. -SJPhone - same as snom -Bria - this is the only phone I could find that works only if the certificate is loaded. Has anybody used other phones with tls and can give me a piece of advice? also, maybe I am not configuring Snom right and that's why it doesn't need a certificate, any ideas? Thanks Catalina

[Kamailio-Users] Perl module and memory leak in append_branch
by James Puckett 26 Aug '09

26 Aug '09

I have followed a bit of the discussions regarding the problems with memory management between the perl modules and the core kamailio software. I need to get append_branch working from within the perl module so that it doesn't cause a memory leak. It's been a while since I did any serious straight C programming, but if someone can point me to the correct way to handle memory allocated with the module so that it gets freed in the core I'd be glad to take this problem on. Specifically, I'm using something that looks like: $m->append_branch("<sip:".$cdpn."\@".$peers{$_}."?From=%3Csip:". $sourcenumber."@".$destIp."%3E;tag=".$fromtag.">", $qval); This leaves about 190 bytes per call unfreed.
