Multiple Line Registrations

Polycom phones can have multiple line registrations.

Each registration requires an address or phone number. Phones registered with Microsoft Skype for Business Server support only one Skype for Business registration.

When multiple registrations are available, users can select which registration to use for certain features, including which registration to use for outgoing calls or when initiating new instant messages.

Note: You must use a unique address or a phone number for each registration. Using the same address or phone number for multiple registrations might cause unexpected behavior.
