[Asterisk-Dev] Real time call control

[Kaloyan Kovachev]

Hi,
 i was trying to do the same (calling card too) and here are the ideas:
  1. external application (via manager interface) to check the call status (to
get the call duration) every X seconds and to terminate the call with hangup
(verry limited, but that's what I'm plannig to do for now)
  2. it would be beter if the macro (Dial with M() option) is executed in
res_features.c (ast_bridge_call) so we can change in the macro the x parameter
for L(x,y,z) (and others) passed from Dial(). This would keep the posibility
to play some massage to the caller. This will require an additional parameter
to M() in order to have it repeated each X seconds, but probably should start
in separate thread not to interupt the call.

As web developer (not C programmer) i can only do 1 with some script, but will
be happy to have the second option implemented.
