Hi Jay,
I think that you would be better served using a Hunt Pilot/Line Group setup in this scenario due to your requirements. Have a look at the following which describes how the Call Forward settings on individual Hunt member phones are ignored when presented a call via the Hunt feature. Here is a clip;
The concept of hunting differs from that of call forwarding. Hunting allows Cisco CallManager to extend a call to one or more lists of numbers, where each such list can specify a hunting order that is chosen from a fixed set of algorithms. When a call extends to a hunt party from these lists and the party fails to answer or is busy, hunting resumes with the next hunt party. (The next hunt party varies depending on the current hunt algorithm.) Hunting thus ignores the Call Forward No Answer (CFNA) or Call Forward Busy (CFB) settings for the attempted party. This also applies to CFWD ALL settings.
From this doc;
http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_administration_guide_chapter09186a00803edabe.html#wp107892
So you would need to use a Hunt Group with the "Circular Hunting" Algorithm and leverage this RNA setting;
RNA Reversion Timeout
Enter a time, in seconds, after which Cisco CallManager will distribute a call to the next available or idle member of this line group or to the next line group if the call is not answered and if the first hunt option, Try next member; then, try next group in Hunt List, is chosen. The RNA Reversion Timeout applies at the line-group level to all members.
Hope this helps!
