[Asterisk-Users] Forward call with response required to accept

[Glenn Dalgliesh]

I am looking for a way to Forward to a external or internal number and require a digit(s) in order to complete forward.   Example:   PSTN1 Calls * dials PSTN2                         if PSTN2 presses proper digits bridge the PSTN1 and PSTN2                         if no response return to a context   Reasons: 2 actually     1. call is forwarded to cell phone but If cell is out of range, turned off, or they don't answer I don't want the calling party to get connected to the Cell phones VM     2. Call is forwarded to outside number and I want a level of security that ensures that the person that the call is intended for is present.   Any help would be appreciated Thanks
