Symptom
Multi-port devices that allow you to configure multiple users on a single MAC address, like ATAs and DECT devices, cannot be configured on users that are on different PBXs.
Applies To
Multi-Port ATAs
DECT Devices
Accounts with Multiple PBXs
Admin Console
Resolution
If a multi-port device is activated on PBX A and a user is on PBX B on the same account, User B should not be assigned to a port on the device. Although Admin Console will not show an error, the user will not be provisioned on the device in the backend and the user will not be able to make or receive calls on their device. Either the User would need to be moved to PBX A or the device would need to be moved to PBX B.
Cause
This is a limitation.
