Hope this helps.
Note that the Trigger and Application also have configurable limits on them that restrict how many calls they can handle concurrently.
I have a questen closely related to that. I WANT a busy signal after so many callers in the queue. So I set the Max Sessions to lets say 3 in the trigger and in the application. Bad thing is, i don't get a busy signal, but an announciation that says "sorry the number you have dialed is not reachable at the moment" (or something like that).
How can i persuade that thing to playout a busy signal for the 4th caller? is there a way?
You could set your script to reject the call if there are no agents available / they are the 4th caller. Personally from the customer services perspective you may be better off setting your script to play a message asking people to call back later if there are no agents available, or also asking them if they want to leave a voicemail.
