SBC rejects SIP INVITE from Kamailio+topos

by José Lopes

Hello, I am using Kamailio working as edge proxy with topos module active. Kamailio is proxing requests from Freeswitch's to the SBC Metaswitch. The Freeswitch sends SIP REGISTER requests and it is ok (Contact: < sip:1003@172.29.210.164:5070>). When Freeswitch sends SIP INVITE quest, it receives a reply with Forbiden (Contact: <sip:btpsh-5aa0219a-2a32-2@172.29.210.164:5070>). You can check the sip trace at https://pastebin.com/raw/JZUNgYx5 I analysed this issue on SBC Metaswitch and it requires that the INVITE and REGISTER have the same Contact Header. I know that this is not required from SIP RFC, but that it is SBC default security policy. There is any way to configure Kamailio using topos to have the same Contact Header on INVITE and REGISTER? Best regards, José Lopes

Dialog Terminator

by Leonardo Assunção

Greetings, Does Kamailio has a method or variable that indicates who cancelled,rejected or terminated a call and, therefore ended the dialog? Currently i'm looking for the sources of BYE's, CANCEL and replies greater than 300 to first INVITE, but i would safer if such a method existed. Thanks in advance

Presence not notifying?

by Mark Boyce

Hi All Got a presence problem with what should be a very simple config. Would much appreciate someone having a look at the following and seeing if I’ve missed something obvious :-) Thanks Mark I’ve gone right back to basics and using the example at http://kb.asipto.com/kamailio:presence:k43-blf <http://kb.asipto.com/kamailio:presence:k43-blf> Changes to that example are; - Kamailio 5.1.2 - RTPEngine - NAT Enabled - JSON RPC replacing mi_rpc - HA1 Passwords Setup is; Three phone 20,21,22 all on site behind a NAT (10.1.3.x local IP) at 1.2.3.4 External IP.

Re: [SR-Users] From URI == Myself

by Fred Posner

If you're not listening or identifying that IP and specific port as an alias, then yes, this is expected. One reason why would be to run another program on that port.

From URI == Myself

by Nicolas Breuer

Hello the List, I saw a strange behavior on the last Kamailio v4. The Kamailio is binding on port 5060. If (from_uri==myself){ ...... } * When the From uri in the INVITE is <xxxx@myalias:5070> * When the myalias is an alias > No issue the IF routine is executed. * When the myalias is the ip address of the server > The IF Routine is NOT executed because there is a mismatch in the port (5060 >< 5070) Is it the expected behavior ? Thanks

ways to track all messages of a dialog

by Fabian Borot

I need to track all messages (SIP Requests, SIP Responses) for some SIP dialogs. Let's say I need to log something specific on each state for calls initiated from a certain IP (initial request, temporary replies, rejection with a negative response, call was accepted with 200, termination with BYE, termination with CANCEL etc. ). I am thinking on using flags but I am not sure after reading the tutorial on flags (http://www.kamailio.org/dokuwiki/doku.php/tutorials:openser-flag-operations) if that is going to work properly. The doc says: "They provide a very easy and fast way of keeping states during processing a request or during a transaction". I am afraid that the ACK if the call is accepted and the BYE won't be tracked properly because they are not part of the initial transaction. Also the doc does not mention if the flag is preserved among branches spawned during the processing of the call. The idea is for example: request_route { if (is_method("INVITE")){ if ($si == "192.168.168.100"){ #condition that would set the flag, INVITE came from "my_IP" #flag/mark dialog setflag(1); #log call from "my_IP" was received } route("INCOMING); } If(loose_route() ){ if (is_method("ACK")){ if(isflagset(1)){ #log ACK related to "my_IP" was received } } if (is_method("CANCEL")){ if(isflagset(1)){ #log CANCEL related to "my_IP" was received } } if (is_method("BYE")){ if(isflagset(1)){ #log BYE related to "my_IP" was received } } } } Then : route["INCOMING"] { # do some processing # do some processing t_onreply("INCOMING"); t_on_failure("INCOMING"); t_relay(); } onreply_route[INCOMING] { #do some processing if(isflagset(1)){ #log a reply related to "my_IP" was received } } failure_route[INCOMING] { #do some processing if(isflagset(1)){ #log a negative reply related to "my_IP" was received } } Will the flags work on this case ? My 2nd approach is to use a htable and use the call_id for my calls as the key. The on each route section (reply, failure_reply, ACK processing etc.) find the $ci on the htable and if it is there do the appropriate action. But I need to delete the key:value once the call ends or leave it autoexpire with a expire value bigger than the max_call_duration_time that we have in our system.

sql_pvquery free result

by Ben Hood

Hi, Does sql_pvquery() clean up after itself? The other query APIs return a result handle that you clean up with sql_result_free(), but sql_pvquery() doesn’t appear to return any handle, so is it self-collecting? Cheers, Ben

Why does all the examples on configuring Kamailio install PostgreSQL

by Wilkins, Steve

Hello All, I have noticed that almost all, if not all examples of installing Kamailio install the PostgreSQL libraries. If one is using MySQL, is there a need for this? Is there something in Kamailio that requires these PostgreSQL libraries to be installed? Thank you

Resend Authenticate REGISTER to two or more Asterisk PBX

by Social Boh

Hello, I'd like know which is the best way to resend a Authenticate REGISTER to two or more Asterisk.
