| Description | The voice interface (DS0 group) becomes disconnected when
the media gateway tries to communicate with the call agent
and the retransmission procedure times out after retrying.
The voice interface (DS0 group) 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 expiration of the timer,
or the reception of call agent command or the detection of
local user activity for the voice interface (DS0 group).
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
call agent. |
