Summary:                    [patch] Fake answer start in app_dial
Description: 
When using H (hangup by "*") or d (exit on DTMF) while invoking Dial(),
this makes app_dial answering incoming channel immediately, not waiting
until outbount channel answers.

I guess this was done to be able to cancel call by hitting "*" not waiting
until it's answered.

But this stuff completely breaks logic for those who perform billing of
the subscribers with Asterisk, because in this case subscribers get CDR
with call duration that is longer that actual (and actually they are
charged money for the calls that were not connected)

---------------------------------------------------------------------- 
most of the Calling Cards applications (like a2billing) propose the service
of this kind:
1) subscriber calls to pre-defined DID number
2) IVR (based on asterisk) prompts to enter PIN
3) subscriber enters PIN 
4) IVR authenticates subscriber and prompts to enter destination number
5) subscriber enters destination number
6) Asterisk places outgoing call and bridges channels together.
7) subscriber hits * to hangup call when he finished a conversation and
returns to IVR prompt i4 (without redialing DID number, entering PIN and
paying for connection!) and can dial new destination number.

With the subj. issue this will be broken!
