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.

Checked 2026-09-25

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.
