Summary:                    Call hangup if send a DTMF  during phone ringing in
DTMF HYBRID MODE
Description: 
If from A phone y dial to B phone, when B phone start ringing, if I press a
digit in A phone, asterisk send:

RQNT 30 aaln/2 at mta248.lab.voip MGCP 1.0 
X: 626395fe
R: L/hd(N)
S: 5

So, even if B phone is ON HOOK asterisk try to send the digit (in this
case "5"), the other phone reply with:

402 30 Phone Already Onhook

And asterisk hangup the call.

I test the same process with asterisk 1.4.4 and asterisk don't send
anything to the B phone before the off hook transition. So when B is
ringing anything happens if I press a digit.

I have a little patch to workaround this problem but is not a good
solution becouse it check for ON/OFF HOOK state before send the digit with
mgcp...
