Limiting the Number of Ports On Hold
When call holding is active for boxes or subscribers, it is recommended that you restrict the number of ports that can be
on hold for any single extension and the total number of ports that can be on hold in the entire messaging system. For
best system performance set the maximum number of calls allowed to hold at one time for an extension to half, or less,
of the total number of ports in the messaging system. When the messaging system reaches the maximum number of
ports allowed on hold, it routes additional callers to the greeting for the extension without asking the caller if they
would like to hold.
To limit the number of ports on hold
In the Navigation Pane, click Switch > Call Holding.
