Hello,

I guess the r-uri is not correct after your changes. you can try to print $ru with xlog(...) just before the route(RELAY).

You should use string operation to add the prefix instead of using a regular expression substitution, like:

prefix("A99901");

or

$rU = "A99901" + $rU;

Cheers,
Daniel

Hello,

 

Thanks in advanced for the help. I am almost new with kamailio and still struggling through silly problems so please forgive me if the solution is so obvious.

 

I have a network like

 

Xlitle -- Kamailio -- GW

 

The GW is more or less out of my reach for changing the behaivour.

As devices I have xlitle

Kamailio is on version 4.0.2

 

I’ve changed only few things from the default config file. Add mysql support, auth, userlocdb, pstngw.

 

For this part, gw routing , I’ve defined gw ip and port inside the PSTN definition like:

#!ifdef WITH_PSTN

# PSTN GW Routing

#

# - pstn.gw_ip: valid IP or hostname as string value, example:

# pstn.gw_ip = "10.0.0.101" desc "My PSTN GW Address"

#

# - by default is empty to avoid misrouting

pstn.gw_ip = "" desc "PSTN GW Address"

pstn.gw_port = "" desc "PSTN GW Port"

 

 

iskratel.gw_ip = "10.XX.XX.XX"

iskratel.gw_port = "5060"

 

#!endif

 

I route the calls with:

   route(ISKRATEL);

 

And defined a routing function

route[ISKRATEL] {

#!ifdef WITH_PSTN

        # check if ISKRATEL GW IP is defined

        if (strempty($sel(cfg_get.iskratel.gw_ip))) {

                xlog("SCRIPT: PSTN rotuing enabled but iskratel.gw_ip not defined\n");

                return;

        }

 

 

        # only local users allowed to call

        if(from_uri!=myself) {

                sl_send_reply("403", "Not Allowed");

                exit;

        }

 

        if (strempty($sel(cfg_get.iskratel.gw_port))) {

                $ru = "sip:" + $rU + "@" + $sel(cfg_get.iskratel.gw_ip);

       } else {

                $ru = "sip:" + $rU + "@" + $sel(cfg_get.iskratel.gw_ip) + ":"

                                        + $sel(cfg_get.iskratel.gw_port);

        }

 

 

 

        # Add profix to ISKRATEL: A99901

        subst_uri('/^sip:(.*)/sip:A99901\1/i'); # add A99901

 

        route(RELAY);

        exit;

#!endif

 

        return;

}

 

 

I can see that the code goes all the way to the route(relay) but all I can see is the 500 I’m terribly sorry, server error occurred (7/SL) and a second response 500 I’m terribly sorry, server error occurred (7/TM)

 

I’ve tried defining the IP as the given pstn.gw_ip and route(pstn) without changing anything on the  pst default routing but the response of the server is the same.

 

I cannot see any special error on the logs.

 

I have the exact same config for this part, in another test server and the calls go to the gw without reporting any error.

 

I’ll appreciate any help from you! Thanks in advanced for your time

 

Helena
