permissions.allow in conjunction with trusted table
by Ben Hood 12 Mar '18

12 Mar '18

Hi, I'd like to trust HTTP requests from internal subnets and use the trusted table to manage permissions from external networks. Is there a way to configure permissions.allow to trust everything on a local subnet and use the DB table for everything else? Does the permissions module even work in that way (i.e. to use two sources of trust)? If so, what is the permissions.allow syntax to trust a CIDR? Or is it better to split the trust up based on listening ports (i.e. define the route blocks so that requests to the port listening for internal traffic is not subject to the trusted table)? I guess I could also add the trusted internal subnet to the trusted table, but this would be mixing application level stuff with devops stuff. TIA, Ben

Hi All Is there any way to extract round trip lime state from keepalives? I have a customer who’d like to duplicate the qualify feature of Asterisk. ie latency / distance of endpoint from server. Can’t see any way to hook in from the docs. Thanks Mark

SBC rejects SIP INVITE from Kamailio+topos
by José Lopes 12 Mar '18

12 Mar '18

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 12 Mar '18

12 Mar '18

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?

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 09 Mar '18

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 09 Mar '18

09 Mar '18

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 09 Mar '18

09 Mar '18

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 09 Mar '18

09 Mar '18

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 09 Mar '18

09 Mar '18

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
