Understanding unnamed registration
prevent unnamed registration, enter an ID or password. The system ignores unnamed
registration after any dialpad entry.
Administrators can disable unnamed registration by appropriately administering the system
parameter UNNAMEDSTAT. For more information, see Administering Avaya IP Deskphone
H.323 9608, 9608G, 9611G, 9621G, and 9641G. Unnamed registration appears to the end
user like Communication Manager TTI Mode and is similar from an administration perspective.
For more information about TTI, see your Communication Manager documentation.
