Enable Multiple Line Registrations
Polycom phones can have multiple registrations; each registration requires an address or phone number.
All VVX phones support up to 48 registration line keys and up to 34 line registrations when connected to
three expansion modules.
You can assign each registration to one or more line keys. Note that you can use a line key for only one
registration. You can select which registration to use for outgoing calls. This feature is one of several
features associated with Flexible Call Appearances.
