Usage Guidelines
When a gateway recognizes that an endpoint has lost its communication with the call agent (has become
disconnected), a timer known as the disconnected timer is initialized to a random value between 0 and
the disconnected initial waiting delay (Tdinit), which is configured with timeout tdinit. The gateway
then waits for one of three things: the end of this timer, the reception of a command from the call agent,
or the detection of local user activity for the endpoint, such as an off-hook transition. When one of the
first two cases occurs, the gateway initiates the disconnected procedure for that endpoint. In the third
case, the detection of local user activity, a minimum waiting delay (Tdmin) also must have elapsed. This
value is configured with timeout tdmin.

The disconnected procedure consists of the endpoint sending an RestartInProgress (RSIP) message to
the call agent, stating that it was disconnected and is now trying to reestablish connectivity.
the call agent, stating that it was disconnected and is now trying to reestablish connectivity.
If the disconnected procedure is unsuccessful and the endpoint is still disconnected, the disconnected
timer is doubled; this is repeated until the timer value reaches the maximum waiting delay (Tdmax),
which is configured with timeout tdmax.

Examples
The following example shows how to set the initial waiting delay value to 25 seconds:
Router(config)# mgcp profile nyc-ca
Router(config-mgcp-profile)# timeout tdinit 25
tdinit-value
Specifies the initial waiting delay value (Tdinit) for the disconnected
procedure, in seconds. The disconnected timer is initialized to a randomly
selected value between 0 and Tdinit. Range is from 1 to 30.
