Since we couldnt find any feature code to BLOCK caller ID via extension,
Customer has requested PSTN carrier to BLOCK all outbound calls.
But on some occasions they want to dial out and show caller ID,
The landline PSTN provider has given a feature code *82 which would enable caller ID to show.
How do we setup the dial plan on the outbound route, so that *82 is added as prefix, for a specific route, so that caller can see the Outbound caller ID.
