Call Control Group
Call Control Group allows you to control the use of CTI ports. Unified CCX uses Unified CM Telephony call control groups to pool together a series of CTI ports, which the system uses to serve calls as they arrive from the Unified CCX server. You can create multiple Unified CM Telephony call control groups to share and limit the resources to be used by specific applications. You can reserve more ports for higher-priority applications or provide access to fewer ports for applications with less traffic.
