Re: [Asterisk-java-users] get queue Hold Time

Hi,

the events you receive contain information about the queue, so you can 
crosscheck if the holdtime you get belongs to the query you sent... or 
you use an unique actionid and check against this to
determine, if the event belongs to your request... I´ve given you a 
working example below.
"can i call function through manager api and get the variables on that 
channel"..?
answer:
you can retrieve channelvariables, but the function you have to call 
first to retrieve the queueparametes (QUEUE_VARIABLES) which in turn 
sets the variables needs a channel... so no chance to use
this without agi (where you always have a channel) without huge workarounds.
The easiest way is to go the way you already started or to use a special 
context in your dialplan... but the example below works without 
modifications of your dialplan.
