Script configuration - External Outbound route (context)

Hello,
i use this software from github.
https://github.com/Nethram/callblaster

My settings are:
Outgoing calls use extension 333 which forces calls to "optional destination" to IVR. (After uploaded contact list, script start calls and connects to the IVR.)

The problem is:
Have current settings for outgoing calls via TRUNK (DongleX).
I want to be able to call from another extension, which is instaled in freepbx and it works normally.

$callFile = "Channel: Dongle/dongle1/$number\n";
$callFile .= "CallerID: $caller_id\n";
$callFile .= "Context: callblaster\n";
$callFile .= "Extension: 333\n";

Task:
Set outgoing connection via another TRUNK (not Dongle).
(Missing - correct outgoing "context" and setting in FreePBX)


I am looking for someone with experience.
