A “Cluster” identifies a connection, used to transport compressed phone calls, between two Abilis. Each cluster is identified with a clear label registered in the Abilis configuration.

Cluster names basically are made by 1 to 8 characters in the range '0'..'9', 'A'..'Z', 'a'..'z', '_', ':' , but to support unified namespace we have to exclude the following combinations:

The following commands to manage the CTI Clusters use:

The d cticl ? command shows all available parameters.

The example below shows how to add the cluster Abilis2 (the number associated to the cluster is 0123456).

A list of cluster numbers (NumClus) is automatically generated by the system; it contains the correspondence between Clusters and their respective numbers.

This list can be used to simplify the structure of the CTI Routings : an unique rule can route all the calls for the Clusters, by verifying the called number configured. See the example in the CTI Routing section further details.

	Caution
	Changes made on the CTI Clusters are not immediately active. To activate them, execute the initialization command init ctisys.

46.4.1. CPO - Call path optimization

The call path optimization allows to optimize the path of calls. Supposing to have the following scheme:

A call is received by Abilis 1 and the operator routes the call toward Abilis 2. Then the remote user reroutes the call toward the Operator. Without CPO the calls (one from Abilis 1 to Abilis2 and one from Abilis 2 to Abilis 1) remain active and can cause a degradation of the quality.

With CPO active the calls drawed with dotted lines are closed and the initial one remains active.

	Note
	CPO feature is available also for IAX and SIP resources.
