Hi Pepelux,
I have this one:
remove_hf("Route");
if (is_method("INVITE|SUBSCRIBE")) {
if($src_ip != "IP ASTERISK"){
record_route();
xlog("L_INFO", "***********ROUTE PSTN***********");
$rU="1005";
} else {
xlog("L_INFO","LLamada desde $si con puerto $sp");
record_route_preset("FQNDDNS:5061;transport=tls",
"FQNDIP:5060");
add_rr_param(";r2=on");
route(DISPATCH);
route(RELAY);
}
}
When the call is from Teams (src_ip != "IP ASTERISK"), incoming calls, I
send the call to 1005 extension. Is here where I have to make the change?
Or where?
Thanks
