Hi Grant,

In CCM 4.1(3) your options are somewhat limited :( The feature that would really help here, is called "CFA Destination Override" and 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;

http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_administration_guide_chapter09186a0080739bb8.html

So, for 4.1(3) you can use IPMA as you nicely noted or perhaps put a second Non-DID line on certain phones that are the Call Forward initiators so that important calls can still be transferred to this secondary number when necessary (even when the Primary Line is on CFWD).

Hope this helps!

Hi Grant,

You are most welcome :) It sounds like you ahve some heavy lifting ahead of you. CCM 6.x has some really great feature sets so many new options will open up for you. If possible get in the lab ASAP and start working with DMA etc. Get yourself a nice head start!

Best of luck,

Rob
