asterisk users - Jun 2007 - second dial, force hangup for exit.

Hello

I make one call:

Account:userid
Channel:Local/966190700
Callerid:fromid <966198098>
Context:default
MaxRetries:2
RetryTime:5
WaitTime:30
Application:mcc2
Data:fromid|callwithid=966198098|accountcode=userid|direct|SIP/fromid@trunk_1|60)

When user answer call, push dtmf numbers, for make a new, call, but, 
dial command in this call, after answer, exit for execute next command.

I probe g command for this dial, but after answer destination, dial 
exit, and hangup call.

any idea ?

thank you !!!
