[asterisk-dev] detect called channel hang-up even with dial application g argument

[Yves]

I see.

so if you don´t have control over server 2 the only way I could think of 
is some kind of external hook... server 3 has to indicate the end of 
call between S2 and S3 somehow
to server 1.
this could be done by calling an URL with call specific parameters or, 
if you have access to server 1 and 3, connect them and close the 
"circuit" back from
server 3 to 1 and use this "channel" as a signalling channel. this 
should be very easy, if server 1 and 3 are on the same network and 
slightly more work, when
the servers operate on different sites.
