5.16.18. Inserting/Removing in a Queue (AMO LDAT) Previous topic Parent topic Child topic Next topic

The term queuing incorporates inserting/removing assignment requests for lines in a queue (trunk/direction).
The term queuing can be described as follows:
  • waiting in the Route Advance Delay queue
  • waiting in the OFF-hook queue
  • waiting in the ON-hook queue
A call can be inserted/removed from a queue in the following two cases:
  1. If the LVAL of all trunk groups is identical and no B channel is found in any of the trunk groups, OFF-Hook Queuing (B) is executed directly.
  2. The trunk groups are prioritized. The call is initially queued via the Route Advance Delay (A) feature. If, however, no B channel is found in the highest prioritized trunk group, OFF-Hook Queuing (B) is executed

Removing calls: If a B channel is free, this is made available to the call already inserted. In this context, the queue (A,B) in which the call is located is irrelevant; assignment of the B channel is based on the prioritization of the inserted call.
The following prioritization applies in this context:
