Use the fast-connect command to enable fast connection for H.323 calls.

Use the undo fast-connect command to disable fast connection.

By default, fast connection is disabled.

As there is no ability negotiation for fast connection mode, the ability confirmation 
of the two parties is determined by the called gateway. When the router acts as an 
originating gateway, you can set whether or not to apply fast connection mode for 
each originated call. When the router acts as a terminating gateway, the 
configuration of the voip called-start command will determine whether fast 
connection is used for call initialization.

Fast connection procedure will be used when both the calling and called parties 
support fast connection. Provided that neither the calling nor the called gateway 
supports fast connection mode, the system will automatically switch to normal 
connect procedure to resume the call.

It is OK to only configure fast-connect command for VoIP voice entity on the 
calling gateway. Just after successfully enabling fast connection can the tunnel 
function be configured.
