MLPP with Shared Lines

MLPP interacts with the phone’s display of shared line call appearances and uses the following precedence rules:

  • When a call is active, incoming higher-precedence call preempts the current active call.
  • If a lower-precedence call is on hold, the preemption screen for the current call doesn’t display.
Note: Polycom recommends you not to change the default value of parameter callsPerLineKey, which may result in improper functionality of MLPP feature for shared lines.
