09 Jan '11

Hello community, I want to test Kamailio 3.1.1 with SIPP. I followed many ideas that I found them on the internet but without no success. In particular, I followed this link http://www.troubleshootingwiki.org/OpenSER#Stress_Test_The_SIP_Signaling I can see traffic from the uac --> Kamailio --> uas ans in the other sens but no successful call. Can you give me any ideas please. Regards, Rochdi

Re: [SR-Users] Change the SIP-To-User

Hi, thanks to all responses. I wonder if there is a function to modify the To/From Header stateful. I mean, change the TO header in the INVITE to A and then the 200 OK (for example) reverse the change back to the previous value to B? but the "magic" $tU is amazing...

RLS server as SUBSCRIBE proxy?
by Jeremya 07 Jan '11

07 Jan '11

Hi, My situation is that I have a number of SIP end points (server) that support SUBSCRIBE method on various resources they hold. Primarily these are dialog resources, but include arbitrary other resources with custom MIME types. I also have a large number of SIP end-points (clients) that use SUBSCRIBE to resources held by these end-points. Some of these end-points are standard phones (SPA-962) monitoring dialog state. Other end points are custom clients that monitor a variety of custom resources and MIME types. I have got to the point where the number of SUBSCRIBE clients is making it impractical for the SUBSCRIBE sources to support them. I want to make a SUBSCRIBE proxy server that makes arbitrary SUBSCRIBE requests to my SIP end points (server) and in turn accepts SUBSCRIBE requests from my consumer SIP clients (Phones etc). In effect the server would aggregate SUBSCRIBE requests into a single SUBSCRIBE to a target resource. Ideally the SUBSCRIPTION would be dynamic, generated by the SUBSCRIBE requests from the SIP phones and other clients, but this can be static. I've read the documentation for the RLS module in Kamailio but I can't actually figure out what it does. It may do what I want (if only in some database mode) but I'd appreciate advice as to whether to pursue this as an option or go to plan-B Regards Jeremy

Hi, ah, thanks. Would be good to have a uac_replace_to. Sounds like a "30min" task to someone familiar with kamailio programming :-) BR, Bernhard ----- Original Message ----- From: Klaus Darilion [mailto:klaus.mailinglists@pernau.at] To: Bernhard Suttner [mailto:bernhard.suttner@winet.ch] Cc: sr-users(a)lists.sip-router.org Sent: Fri, 07 Jan 2011 21:59:55 +0100 Subject: Re: [SR-Users] Change the SIP-To-User > Bernhard Suttner wrote: > > Hi, > > > > thanks to all responses.

Hi everyone, Again stuck at the dispatcher module.Do anyone happen to have a working config for kamailio with dispatcher list from mysql database ? if not can someone please guide me on this ? Do i need to pass module parameters for the column and the table names ? I have the following config : loadmodule "dispatcher.so" if(uri=~"^sip:1[2-9][0-9]{9}@") { if(is_user_in("credentials","longdistance")) { #route(PSTN); #exit; ds_select_dst("1","8"); forward(); } else{ sl_send_reply("403","No Permissions for Long Distance calls"); exit; }; }; -- Thank You Amit Nepal

Dispatcher Attributes field
by alex pappas 07 Jan '11

07 Jan '11

Dear all, I'm trying with the Dispatcher module to terminate a call to three different gateways serially. For each gw I use the attribute field to get the attribute and add it as a prefix to the RU. The problem is that the $avp(dsattrs) is returning always the first value of the first gw that is using. example: destination sip:100.12.12.12:5060 attrs 111 destination sip:100.12.12.11:5060 attrs 222 destination sip:100.12.12.10:5060 attrs 333 In this example the rU will always be 111+number. I tried also to initiate the avp in the Failure route by giving null value but still does not change the result. In Request route: if(ds_select_domain("$avp(s:disp_dstgrp)", "4")) { $avp(s:term_prefix) = $avp(dsattrs); # avp for CDR purpose $rU = $avp(dsattrs) + $rU; t_on_failure("FAIL_NATIONAL"); t_relay(); exit; } In Failure route: if(!ds_next_domain()) { t_reply("503", "Service Unavailable"); exit; } else { $rU = $avp(dsattrs) + $rU; t_on_failure("FAIL_THIS"); append_branch(); if(!t_relay()) { t_reply("503","Service Unavailable"); exit; }
