I’ d like to simply check if something is possible or not, without really having to know how to achieve it programmatically (I’ll figure that out).
Suppose you use a mobile phone as a handset to an asterisk pbx. You program the pbx’s number as a shortcut and when you want to call anyone, you simply call the pbx and with DTMF you tell it dial the number. So far so good.
A problem might arise when you are receiving a call and you want to forward: at that moment can you tell Asterisk to put the open channel on hold with DTMF and forward it to another extension? and also get it back when the extension doesn’t answer?
I’m thinking of using a mobile phone as wireless handset to escape from expensive wireless infrastructures.
