Hi Mohamed,
Maybe this will help (you do not need CUE for this);
The number of simultaneous calls that Cisco Unified CME B-ACD can handle is limited by the number of PSTN ports, but these ports may not always be in use. For example, you could have three queues with ten slots per queue, but configure only 10 ports instead of 30 because you do not expect the three queues to ever be full at one time.
Cisco Unified CME B-ACD is available for outside calls through voice ports and trunks, for which dial peers must be set up. When you set up a dial peer, you use the service command to associate it with the name of the Cisco Unified CME B-ACD AA service that you want callers to that dial peer to reach.
Note You must configure a dial peer for each incoming DID voice port.
To determine how many ports or trunks you must have for your Cisco Unified CME B-ACD service, consider the following:
Total number of phones across all ephone hunt groups
Total number of slots in the queues across all queues
Total number of PSTN ports feeding into the queues
A maximum of ten call queues and ephone hunt groups can be used with the call-queue script. An AA can use a maximum of three hunt groups from those ten, but an AA can also use fewer than three hunt groups or several AAs can share one or more hunt groups. A shared operator hunt group is not included in that maximum; you can add a shared operator hunt group in addition to the three hunt groups that an AA uses, or it can be part of the three hunt groups. The maximum number of calls that can be in queue for each of the ten possible hunt groups is 30, so a potential of 300 calls can be queued.
The following characteristics summarize Cisco Unified CME B-ACD properties:
A maximum of one call-queue service can be used with any number of AA services.
A maximum of 10 ephone hunt groups can be used with a call-queue service. Each ephone hunt group can have up to 20 extensions.
A maximum of three ephone hunt groups can be used with an AA service; a hunt group that is used as an operator hunt group may be separate or may be one of the three groups.
An ephone hunt group can reserved for a single AA or can be shared among several AAs.
The maximum number of calls that can be queued for an ephone hunt group is 30.
The digit 0 always maps to the hunt group with the highest aa-hunt number in the configuration.

Hope this helps!
