| Description | The endpoint becomes disconnected when it tries to communicate
with the call agent and the retransmission procedure times out
after retrying.
The endpoint in disconnected state starts the disconnected timer
initialised to the random value and uniformly distributed between
1 and initial waiting delay (Tdinit) in seconds.
The gateway waits for either the end of this timer, or the reception
of call agent command or the detection of local user activity for
the endpoint.
When the disconnected timer elapses, or when a command is received
from the call agent or when there is a local user activity, the
Media Gateway sends the Restart In Progress command with the restart
method as RM:disconnected to the Media Gateway Controller.
In case of local user activity, a provisionable disconnected
minimum waiting delay (Tdmin) must have been elapsed since the
gateway became disconnected.
The minimum waiting delay (Tdmin) timeout value used by the
Media Gateway to send the Restart In Progress with the restart
method as RM:disconnected to the Media Gateway Controller if
there is any local user activity is defined by this object.
Media Gateway initiated delete connection (DLCX) or restart in
progress (RSIP) commands are not considered as local user
activity.
The events observed on the TDM interface or on the network
constitute the local user activity.
The recommended value of this object is 15 seconds. |
