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 the timeout tdinit command.
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 the timeout tdmin command.

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

Examples
The following example shows how to set the minimum timeout value (Tdmin) to 20 seconds:
Router(config)# mgcp profile nyc-ca
Router(config-mgcp-profile)# timeout tdmin 20
tdmin-value
Specifies the minimum timeout value for the disconnected procedure
(Tdmin), in seconds. Range is 1 to 30.
