[asterisk-dev] Call Intrusion

[Moises Silva]

I'd not make the analogy with chan spy, you basically just want
un-bridge/bridge functionality. You can achieve that with this patch
for 1.4:

http://bugs.digium.com/view.php?id=5841,

The mechanism to steal a channel is basically known as masquerading,
and it's an ugly process to look at, but you can do so at
main/channel.c in ast_do_masquerade().

I've heard about a better bridging API in 1.6, but I cannot say
anything about since I have not used it yet.

I don't think you need to write a new Asterisk application, you just
need to use the Bridge sutff either for 1.2/1.4 or the new bridge
stuff for 1.6 which I am sure someone else will point out here.
