Source note · Unified CM Device Mobility
When the Call Forward All CSS activation policy uses the device and line CSS, a phone roaming within its device mobility group gets the roaming pool's Device Mobility CSS plus the line CSS as its CFA CSS; at home, or when roaming across groups, the home CSS is used.

If the device is roaming within the same device mobility group, the device mobility CSS from the roaming device pool and the line CSS are used as the CFA CSS.
