[Asterisk-Users] problems with analog interface to PBX

[Dan Fernandez]

Yes, I've tried with SendDTMF, and it works, but if I do that, then * looses
control of the call. That is, the call is transfered to the new extensions
on the PBX but since * is not in the calll flow anymore, it doesn't know if
on the other end they have ansered or not.
