Hi there,

I'm new to Asterisk. I need to call (from dialplan) a 
macro or a gosub or an AGI upon one of the connected party in a bridged 
call (on sip trunk) puts the call on HOLD. Anyhelp greatly appreciated

PS:
 I looked into app_dial.c if I can capture AST_CONTROL_HOLD event, and 
call a macro, however once ast_bridge_call() is called, Dial app does 
not get mid-call events on the call (like 
AST_CONTROL_HOLD/AST_CONTROL_UNHOLD)

I also tried to use frame_trigger.c but it didn't work too. I understand this is not a good approach.

Thanks,
Uma
