In your ARS modified digits do you have any digits inserted before dialing?
e.g. {000}
If not, then call by call is not active
Forms:
[ul]
[li]Bearer Capabilities[/li]
[li]Calling Line ID Restriction <-- This is the one you want to be Call by Call[/li]
[li]PRI/QSig Network Specific Facilities[/li]
[/ul]
You can leave Bearer and Network at default and only set Calling Line ID restriction to Call by Call.
In this case, you would need {0} (Send digits) and {1} (Don't send) in your modified digits.
If yes, then you need to build a route that uses {001} instead.
Then either get your users to dial a different access code, or COR restrict them from the standard routes and force them to the alternate routes.
