We have 8 Devices (6 DECT and 2 Analog Lines)... The six DECT-Phones are registered on the AVM as VoIP-Phones and use our PBXes-System directly.
What would be the advantage If I registered the Fritzbox as SubPBX of PBXes? Also now are the phones registered - thru the VoIP-Login of the Fritzbox . in the PBXes-System.
Could you tell me some advantages where this feature can be used for?
