Chapter 13 Time Limit Call Service
13.1 Overview
13.1.1 Introduction to Time Limit Call Service
The time limit call service is used to control the call duration within a specific period. If
the time limit call service is enabled for a subscriber, all calls that this subscriber makes
cannot exceed the time limit; otherwise the call will be terminated automatically.
Using of the time limit call service requires devices including gateway and terminals.
13.1.2 Time Limit Call Mechanism
The call duration is determined by the settings of the caller and the callee. When either
the caller or the callee sets the time limit call service, the call duration will be restricted.
The shorter call duration limit is adopted for the call.
The following table describes the rules for the call duration.

If the caller ID is anonymous, since the call duration time limit of the caller is
unavailable, the call duration limit of the callee will be adopted for the call.

The call duration is not restricted by the maximum call duration limit of the recipient
if either party in a time limit call uses the call transfer service.

If a third party uses the call intervention service during a limit time call, the call
duration is reset after the third party ends the call with the callee.
