I have a person ext: 8002 who has his phone set to call forward all to ext: 8001. If the person at ext: 8001 has a caller that wants to talk to the person at ext: 8002 how do they send the call to them. They used to do this via an intercom with the legacy avaya pbx. How do you do this in Call Manager?
Cisco Unified CallManager provides a service parameter (CFA Destination Override) that allows the administrator to override Call Forward All (CFA) when the target of the CFA calls the initiator of the CFA, so the CFA target can reach the initiator for important calls. In other words, when the user to whom calls are being forwarded (the target) calls the user whose calls are being forwarded (the initiator), the phone of the initiator rings instead of call forwarding back to the target. The override works whether the CFA target phone number is internal or external.
When the CFA Destination Override service parameter is set to False (the default value), no override occurs. Ensure the service parameter is set to True for CFA override to work. See Service Parameters Configuration in the Cisco Unified CallManager Administration Guide, Release 5.0(4), for information about configuring service parameters.
Note CFA override only takes place if the CFA destination matches the calling party and the CFA Destination Override service parameter is set to True. If the service parameter is set to True and the calling party does not match the CFA destination, CFA override does not take place, and the CFA remains in effect.
I changed the Service Parameter setting to True. It now allows me to transfer the active call to ext: 8002, but goes directly to their voice mail. Is there a way for it to ring so the person can answer the phone?
