[cisco-voip] CUCM 6.1 Forwarding

[Lelio Fulgenzi]

I think someone one the list mentioned this a while back. In pre 5/6 if you had nothing configured on for forwarding CSS it used the device/line CSS, basically following what the rest of the phone had. With 5/6 you must specifically assign it something. I believe there are two forwarding CSS so you can use the device/line approach with forwarding as well.

Call Forwarding Enhancements 
The Call Forward All (CFA) enhancement introduces a secondary Calling Search Space (CSS) for the Call Forward All field. The secondary CSS for CFA combines with the existing CSS for CFA to allow the support of alternate CSS system configuration. 

When CFA is activated, only the primary and secondary CSS for CFA gets used to validate the CFA destination and redirect the call to the CFA destination. If these fields are empty, then null CSS gets used. The combination of the line CSS and device CSS no longer gets used when CSS for CFA is None. Only CSS fields that are configured in the primary CSS for CFA and the secondary CSS for CFA fields get used. 

For more information, refer to Cisco CallManager Features and Services Guide 5.0. 

Cisco CallManager Administration Configuration Tips 

.You must configure either primary Forward All Calling Search Space or Secondary Forward All Calling Search Space or both for Call Forward All to work properly. The system uses these concatenated fields (Primary CFA CSS + Secondary CFA CSS) to validate the CFA destination and forward the call to the CFA destination.

  Whats the deal with the CFA on CUCM 5/6? I thought if you enabled the
  service parameter "Calling Search Space Activation Policy" for "with
  activating Device/Line CSS" It would use the settings from the device for
  forwarding calls. I find I must set a CSS on the forwarding containing the
  part I wish to reach. Am I missing something here? Thoughts appreciated.

  My goal is to have a CFA that is the same for every site, with the ability
  to call local, and use the appropriate GW set at the device. Thoughts
  appreciated!

  I'm grabbing a debug next. TIA
