Disclaimer: I'm not familiar with all the mods of FS, There may be one that does this already.  There are probably many ways to do this, I am just offering one that works well for me.

Item #1 - Findout the callee #.   "destination_number" can be set to several different things based on the gateway configuration (forced override with an extension) and may or may not start with a "+" so the example below may not work.  To make matters worse, different gateways set fields differently when they hand off the call.  The most reliable I've found is "rdnis" or "sip_to_user" , however if you know you are going to stay with one gateway, you can relay on the oddities of the way they are configured.  I had to write something relatively generic, so I moved all processing to a script (see #3 below)

Item #2 - Find the caller ID. This is located in "caller_id_number", but remember in your processing that caller ID may be "anonymous", "restricted", "unknown" or some other word when dealing with blocked/private numbers.  You cannot looks for just numbers.

Item #3 - Routing.  As I mentioned I have 100s of numbers across many gateways, so I needed a way to route the calls to the right places AND know which gateway the call came in on, so I can bridge the call out the same gateway.  I handled this by creating a small DB table (using postgreSQL) and connecting using LUA and luasql.  The table has three fields: number, gateway, and extension to route to.  In my public.xml I list all the places a call can be routed to and the last entry is a unconditional transfer to the "switchboard" script.  The switchboard script matches "rdnis" and "sip_to_user" to find the callee and then performs a lookup for the extension to route to.

If you would like a copy of my switchboard script I can provide it to you in a PM.

configure?)

No, it is more like static routing. I need my script program be invoked when somebody dial in. That is it. One script for all inbound DIDs. Suppose I have thousand of them.  I think I know how to accomplish this but I am not sure yet.

in my dialplan I need to define:

<!-- Launch a JavaScript application if dialed in-->
   <extension name="ProviderABC">
    <condition field="source" expression="mod_sofia"/>
    <condition field="destination_number" expression="^1NXXNXXXXXX$">

     <action application="javascript" data="/usr/local/freeswitch/scripts/myapp.js"/>
    </condition>
   </extension>

In provider configuration:

<gateway name="voicepulse">
           <!--/// account username *required* ///-->
           <param name="username" value="your-username"/>
           <!--/// auth realm: *optional* same as gateway name, if blank ///-->

           <param name="realm" value="nyc.voicepulse.com"/>
           <!--/// account password *required* ///-->
           <param name="password" value="your-password"/>

           <!--/// extension for inbound calls: *optional* same as username, if blank ///-->
            <param name="extension" value="1NXXNXXXXXX"/> 
           <!--/// proxy host: *optional* same as realm, if blank ///-->

           <param name="proxy" value="nyc.voicepulse.com"/>
           <!--/// expire in seconds: *optional* 3600, if blank ///-->
           <param name="expire-seconds" value="600"/>


	   <param name="register" value="true"/>
         </gateway>

Something like this, yes? I can use regular expressions in destination_number?

Q: There is object Session in JavaScript, Lua. Is Session.destination == destination_number from incoming call? It is not clear for me from what I have read so far.

TIA,

Hi, everybody

This is a newbie question: Suppose I have XX (variable dynamic number) DIDs assigned to one sip trunk (from VOIP provider ABC ). All calls coming from VOIP provider ABC MUST be routed to the same lua/js/whatever script. Is it possible in FS? If yes, how everything should be configuered? Dialplan, sip gateway? One more question: suppose it is doeable as I hope then how can I get in my script CalleeID (not a CallerID)? Basicaly,

I want to acomplish the following:

1. Avoid re-configuring FS every time I got new bunch of DIDs assigned/released from/to my Voip provider.
2. Have a way of extracting CalleeID in my script.

TIA,

Vladimir Rodionov
