[Asterisk-Users] Detecting when a called mobile is not reachable?

[Rod Bacon]

This is quite interesting.

I tested calls to 2 mobiles that I knew were off, and not diverted to 
voicemail. 1 with Telstra, the other with vodafone (I'm in Australia). Via 
ISDN, both calls were shown as unanswered by asterisk. When the calls went 
to voicemail, the call was deemed to be answered.

Via analogue circuits, the call is shown as answered, no matter what.
