Communication Manager provides comprehensive end-user telephony features (such as auto attendant, call transfer, call forward) that facilitate effective communications among employees, customers, and partners.

Mid-call features

Communication Manager ensures that mid-call call telephony features work when Avaya endpoints establish video calls with Radvision endpoints. Customers can use video mute, unmute, transfers, and conferences during a video call.

Exclusion

Users can maintain the privacy of their telephonic conversations and ensure that unwanted parties cannot join the call. You can use Exclusion with Extension to Cellular, Bridge Call Appearance, Service Observing, and Multiple Device Access.

Concurrent call management

If the Limit Number of Concurrent Calls (LNCC) feature is enabled on a station, Communication Manager restricts the number of incoming calls to one call at a time. If the user is busy, the subsequent incoming calls receive a busy tone. Communication Manager Release 6.2 and earlier supported this feature on H.323 and DCP telephones. Communication Manager Release 6.3 extends this support to SIP telephones.

Automatic Number Identification (ANI)

Displays the telephone number of the calling party on your telephone. The system uses ANI to interpret calling party information signaled over multifrequency (MF) or Session Initiation Protocol (SIP) trunks. Any display telephone can use ANI.

For H.323 and DCP endpoints, the caller information on the bridged call appearances can be set to be the same as the caller information on the principal station. To enable this feature, set the Match BCA Display to Principal field on page 2 of the Class of Service screen to y.
