I don't know if this is even possible. I might be totally wrong but once 
this call is on the cell network, how are you gonna communicate with 
asterisk?? From what I understand, while the voice (RTP) traffic still 
travels through asterisk, You have no access to any kind of signalling. 
Please correct me if I'm way off base here, anyone.
