Cisco CallManager release 5.0 supports a secondary Calling Search Space (CSS) for Call Forward All (CFA) field. The secondary CSS for CFA combines with the existing CSS for CFA to allow the support of the alternate CSS system configuration. When CFA is activated, only the primary and secondary CSS for CFA get used to validate the CFA destination and redirect the call to the CFA destination. If these fields are empty, the null CSS gets used. The combination of the line CSS and device CSS no longer gets used when the CSS for CFA is None. Only the CSS fields that are configured in the primary CSS for CFA and secondary CSS for CFA fields get used. If CFA is activated from the phone, the CFA destination gets validated by using the CSS for CFA and the secondary CSS for CFA and the CFA destination gets written to the database. In previous releases, if the CSS for CFA is empty, the CFA destination got validated against the combination of the line CSS and device CSS of the phone. In this release, when the CFA is activated, the CFA destination always gets validated against the CSS for CFA and the secondary CSS for CFA.
Are both Cluster A and B running version CCM 4.x ? If this is the case then I would expect the CFA to use the Line/Device CSS if no CSS was specified.
With regards to the Secondary CSS, this provides the opportunity to configure a CSS which provides PSTN breakout. This can be a problem when using the Device and Line CSS approach. The device CSS which provide the external breakout, however CFA no longer uses the Line/Device CSS, hence the secondary CSS.
Not directly answering your question but, I think you would want to take advantage of this as a security feature. Leaving the CFNA to the default Class of restriction (under the premise of this would inherit the same COR as the device), would allow for user Toll fraud. Just because I can call Granny in England directly does not mean by default I should be able to to have my co-worker forward his phone or mine to her and I call in after hrs.
