So, new IPO system with a PRI for an insurance company. The catch is that they have a tenant that is a different business with his own two analog lines. I set the incoming group ID to 1 (from the default 0) and then routed all calls coming in on those 2 trunks to his extension, that was easy. Now how do I limit his outgoing calls to only use the two analog trunks instead of leeching off the PRI for outgoing calls?
