We’re growing a name answering service for small companies. When our buyer is busy, telephone calls to them could be forwarded to our enterprise’s VoIP telephone quantity as a substitute of going to voicemail.
Busy name forwarding is supposedly supported by all US mobile infrastructures (Verizon, AT&T, T-Cell).
Up to now, each Verizon/AT&T consumer we check with is ready to set this up. However at any time when we attempt setting this up with a T-Cell consumer (or a cell model that operates on the T-Cell community), setup both fails, or succeeds however then busy calls should not forwarded, or they often are.
We now have spent hours experimenting with completely different name forwarding and reset codes ourselves (*21, *61, *62, *67, 004, ##004#, and many others) and on the telephone with T-Cell technical assist, however to this point haven’t found out a transparent set of setup directions that at all times work reliably.
Has anybody else encountered this problem and is aware of how you can deal with it? We’d be prepared to pay $250/hour to seek the advice of with an knowledgeable on this matter.
This places T-Cell beneath a destructive gentle vs Verizon / AT&T, which is an actual pity for them.
