The RestartMethod parameter specifies the type of restart, encoded as one of the
following keywords:
graceful: A "graceful" restart method indicates that the specified endpoints will be
taken out of service after the specified delay. The established connections are not yet
affected, but the call agent should refrain to establish new connections, and should try
to gracefully tear down the existing connections.
forced: A "forced" restart method indicates that the specified endpoints are taken
abruptly out of service. The established connections, if any, are lost.
restart: A "restart" method indicates that service will be restored on the endpoints after
the specified restart delay. There are no connections that are currently established on
the endpoints.
disconnected: A "disconnected" method indicates that the endpoint has become
disconnected and is now trying to establish connectivity. The restart delay specifies
the number of seconds the endpoint has been disconnected. Established connections
are not affected.
cancel-graceful: A "cancel-graceful" method indicates that a gateway is canceling a
previously issued "graceful" restart command.
Example
RM:restart
RestartDelay (RD)
The restart delay parameter is expressed as a number of seconds. If the number is
absent, the delay value is considered null.
In the case of the "graceful" method, a null delay indicates that the call agent should
simply wait for the natural termination of the existing connections, without establishing
new connections. The restart delay is always considered null in the case of the
"forced" method. A restart delay of null for the "restart" method indicates that service
has already been restored. This will typically occur after gateway startup/reboot.
EventStates (ES)
The EventStates parameter is encoded as a comma separated list of events.

Capabilities (A)
The Capabilities parameters inform the call agent about capabilities of endpoints
when they are audited. The encoding of capabilities is based on the
LocalConnectionOptions encoding for the parameters that are common to both. The
parameters used are Event Packages (v), Modes (m), a list of supported codec (*),
type of network (nt), and so on.
