Routing rules written in script using Yate's Javascript module.
Contents |
Configure script in Javascript module
To configure a script for Javascript routing it must be listed in the javascript.conf file:
[general] routing=example.js
Configure a gateway
The example.js for outside routing requires to configure accfile.conf:
[gwout] enabled=yes protocol=sip username=outcalls password=mypass registrar=a.b.c.d
Routing Script
Write example.js in /share/scripts where Yate scripts are.
// First display calling and called party numbers
Engine.output("Got call from '" + message.caller + "' to '" + message.called + "'");
if (message.called.substr(0,2)=="19") {
// route calls starting with 19 to 192.168.168.1
// 5060 is the default SIP port. When using the default port you don't need to specify it
Channel.callJust("sip/sip:" + message.called + "@192.168.168.1:5060");
} else if (message.called.substr(0,2)=="00" && message.called.length>10) {
//route calls using a function
routeOutside();
} else if (message.called.match("^60")) {
//route calls starting with 60 to 192.168.168.1
Channel.callJust("h323/"+message.called+"@192.168.168.1:1720");
} else if (message.caller=="209") {
//route calls from caller: 209
Channel.callJust("iax/user_iax@192.168.168.1:4569/"+message.called+"@iaxcontext");
} else {
//route other calls that don't match the above rules
Channel.callJust("wave/play//var/spool/sounds/hello.au");
}
function routeOutside()
{
// rewrite caller number for all calls that will be routed to this account
message.caller = "+40211231234";
// rewrite called number: strip 00 and add +_in front of the number
message.called = "+" + message.called.substr(2);
// send all calls starting with +40 to line "gwout" defined in accfile.conf
message.line = "gwout";
Channel.callJust("line/"+message.called);
}
How it works
When a call is coming in a new instance of the already parsed routing script is created and associated with the inbound call leg.
The main code flow (that is, outside any function) is then executed after setting the call.route message parameters in the message variable. The Javascript code can make decisions based on these parameters and can call methods of the Channel object to route the call to the desired destination.
