My dialer app query a database and dials out and once connected triggers another app to play out prompts. At a time there are 40 - 50 numbers to be called. My sip trunk has only 6 members. The Dialer attempts all the calls in one shot to the trunk, not taking in consideration that there are only 6 channels and wait for the channels to come free, obviously only the first 6 goes out. Is there a way to make the dialer to queue the calls to the trunk or dial them in chunks of 6 calls at a time?
