Hi,

My client want to make a forward all from phone A to phone B and allow phone B and only phoneB to call phone A.

He says that its possible an all other system (Alcatel...) and cannot beleive that it is not possible here.

Is there parameters to set to enable this feature or it is really impossible.


Thanks

Hi Luc,


This feature, which is called "CFA Destination Override" is available in CCM 5.X and CCM 6.x. Have a look;


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.


From this CCM 5.1.(1) doc;

Hope this helps!

Thanks very much, I'm running 4.1(3) so need to wait. But users said that its the first time its not native in a telephony system !! True it has been always in an Alcatel system, I need to argue !! :-)


Thanks

Hi Luc,


You are most welcome :) I come from a Nortel background and this feature has always been there as well, but Cisco IPT is still really in its infancy in comparison. These good features are coming on stream all the time some of them give us the push to upgrade to these new versions.


For this particular feature I have always found a work-around using a secondary number on users phones that are not accessable from the outside world and can be used for Internal communication and to Transfer **important calls** when necessary.


Hope this helps!

Rob

Thanks, that's the workaround we think about, a kind of "proxy" line for each manager.
