This is to clarify the "forwarding to an extension, PSTN number or SIP URI" question that keeps coming up. I can spot the following places where we give the admin an opportunity to insert a "forwarding to" number:

1) User call forwarding (user and admin portal)
2) Personal auto-attendant (zero-out extension)
3) Personal auto-attendant (user defined keys 1 through 9)
4) ACD queue overflow extension
5) Auto-attendant Goto Extension
6) Auto-attendant transfer on invalid input
7) Hunt group fallback destination

This issue is to get to a) clarity and b) consistency in terms of what input is allow in these fields. Ideally, all these transfer locations should be any internal number, PSTN numbers, and SIP URIs. Could someone please point out what the current state of affairs is, so that we at least can add the correct help text information?
