Can someone please help me understand the 'Call Forward All' Calling Search Space settings on CUCM 6.1.
Under CM Service Parameters I have set 'With Activating Device/Line CSS' and under the line configuration left it as 'Use System Default'
Can anyone confirm that this option means that the CSS on the Line or Device will be used for the CSS for CFwdAll.
Secondly does this only apply to Line 1 as when I configure CFwdAll under line 2, it will not work unless I specify a CSS to use.
Below is the description of the Service Parameter, taken from CM
With Activating Device/Line CSS - the primary and secondary CFA Calling Search Space will be updated with primary line Calling Search Space and activating Device Calling Search Space. Note that the primary CSS and secondary CSS on line page will be updated when activating CFA on a phone, where primaryCSS = lineCSS, and secondaryCSS=device CSS. Special cases include the following:
1. if lineCSS=null, then primaryCSS=null, and secondaryCSS=device CSS
2. if deviceCSS=null, then secondaryCSS=null, and primaryCSS = lineCSS
3. if lineCSS=deviceCSS, then primaryCSS=lineCSS, secondaryCSS=null. This is a required field. Default: With Configured CSS
Any comments will be appreciated.
