[cisco-voip] External Phone Number Mask & Call Routing

[Lelio Fulgenzi]

This is correct. You must have an external mask in order to dial toll free numbers. I believe you need an external mask to dial 310-XXXX numbers as well. The reason behind this, I believe, is routing/access. A customer can set up a toll free number so that it is only reachable by certain area codes, i.e. local client must dial the non-toll free number.

Strange problem. We discovered that if a DN does not have an “external phone number mask” configured, the set will not be able to dial a 1-8XX number. It can dial any long distance number but not a 1-8XX number. The route patterns of the 1-8XX numbers are configured with the same options as the long distance route patterns. What is the relationship between an external phone number mask and call routing?
