The Javascript module offers support for programmatically routing a call.
Using the example below you will learn how to:
- route calls starting with specific blocks of numbers to the desired destinations
- route calls to a specific gateway set in accfile module
Contents |
[edit] Configure script in Javascript module
To configure a routing script you must list it in the javascript.conf file.
Parameter routing from [general] section must contain the name of the script.
[general] routing=example.js
[edit] Configure a gateway
In order to route outside, a gateway is required. To set the gateway you must configure it in accfile.conf.
[gwout] enabled=yes protocol=sip username=outcalls password=mypass ;the registrar has the following format IP:port registrar=192.168.168.1:5060
[edit] Routing Script
This is the example.js script.
By default your script should be in share/scripts directory from Yate sources.
// 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 if(message.called.substr(3) == "+40") // alternative: if(message.called.match("^\+40.*")) { message.line = "gwout"; } Channel.callJust("line/" + message.called); }
[edit] How it works
When a call is coming, a inbound call leg is created.
The inbound call leg is associated with a new script instance.
The parameters in the call.route message are set in the message variable.
Then the main code flow(that is, outside any function) is executed.
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.
