Hi there

I have made the changes but it still gives me a 404 error. The PSTN is based in London, but what is confusing me is the interconnect dial example. What do you think?

Best regards,

Colin

Hi Colin,

Based on your interconnection description you should send 666#country code + area code + tel no.

How do your users dial? Do they dial 9 + 00 + country code + area code + tel no. Or do they dial 9 + country code + area code + tel no.?

If it's the first one try this

       # attemt handoff to PSTN
if (uri=~"^sip:9[0-9]*@ gaco.co.za") {
log ("Forwarding to PSTN\n");
          strip(3);
          prefix(666#);
          rewritehostport("217.15.11.87:5060");
t_relay_to_udp(" 217.15.11.87","5060");
          break;
};

if it's the latter
       # attemt handoff to PSTN
if (uri=~"^sip:9[0-9]*@ gaco.co.za") {
log ("Forwarding to PSTN\n");
          strip(1);
          prefix(666#);
          rewritehostport("217.15.11.87:5060");
t_relay_to_udp(" 217.15.11.87","5060");
          break;
};

I have done all of this, but it does not work. Can I perhaps send you the ser.cfg file?

You aren't putting the handoff to PSTN part in the right place. It should be as follows;

if (uri==myself) {

if (method=="REGISTER") {

# Uncomment this if you want to use digest authentication
if (!www_authorize(" gaco.co.za", "subscriber")) {
www_challenge("gaco.co.za", "0");
break;
};

save("location");
break;
};

       # attemt handoff to PSTN
if (uri=~"^sip:9[0-9]*@ gaco.co.za") {
log ("Forwarding to PSTN\n");
t_relay_to_udp(" 217.15.11.87","5060");
          break;
};

               # native SIP destinations are handled using our USRLOC DB
if (!lookup("location")) {
sl_send_reply("404", "Not Found");
break;
};
};
# forward to current uri now; use stateful forwarding; that
# works reliably even if we forward from TCP to UDP
if (!t_relay()) {
sl_reply_error();

};
}

I have a big problem handing my call of to the PSTN, It give me a 404 error (not connected). What can I do to fix this?

My handoff script looks like this:

if (uri=~"^sip:9[0-9] *@ gaco.co.za") {

log ("Forwarding to PSTN\n");

prefix("666#");

t_relay_to_udp(" 217.15.11.87","5060");

break;

};

The PSTN interconnect description:

1) I need to send a prefix of 666# followed by full intl number without leading 0's.

eg. 666#442071016211

2) The PSTN are connecting me to a Cisco SIP Proxy server, which uses Tech-prefixes eg 123# to separate and authenticate the calls into different domains.

What can I do to get it working?
