Thanks Benny, that's great info that I didn't think of. So we want to send the number out, but notify our provider that it shoud be hidden unless it's a call to 911 or something. What we have is a SIP connection, not a PRI, is there anyway to do something like that with SIP? Would that be provider-specific?
