[asterisk-users] Reinvite after DTMF?

[Wilson Pickett]

Is there a way to do the following scenario?

1) my asterisk box receives an incoming call from a toll free number
provider such as nufone, voicepulse, etc.
2) It then dials a number  via SIP and outputs a  DTMF  sequence.

ok, that part we do every day.

3) After DTMF though, is it possible to get the two SIP channels
(original SIP caller plus SIP called) hooked together and have my pbx
no longer in the call at all?
