[Asterisk-Users] Get the Caller-ID without Answering

[George Burt]

Thanks, but that does not actually terminate the call.  The phone continues
to ring until the caller hangs up.

I have done an application with cellphones that allowed allowed me to send a
signal to the phone company to drop the call.  Maybe this is just a cell
phone thing.
