Allocate an incoming DID or LDN extension for incoming DPT calls.
This extension can be shared by IGAR and DPT.
Ensure that enough trunks are available for IGAR.
You do not need to set the maximum number of trunks for DPT.
Use existing routing techniques to ensure that an outgoing DPT call from a specified network region has access to an outgoing trunk.
The outgoing trunk need not be in the same network region as the calling endpoint if the endpoint and trunk network regions are interconnected.
