before the gateway (GW) receives a Connect message, avoiding H.245 message exchange on
TCP connection, and thereby shortening connection time. There is no capability negotiation
process in fast connection mode, so the capability of both parties is determined by the
terminating GW. When fast connection is enabled, a Setup message sent from the originating
GW carries locally supported codecs. After receiving this message, the terminating GW selects
one suitable codec to notify the originating GW through a CallProceeding, Alerting, or Connect
message. In this way, both parties adopt this codec for communication.
•
Tunneling means that in fast connection mode, non-standard H.245 messages (for example,
transparent transmission capability of DTMF digit) are encapsulated in an H.225.0 Facility
message to complete capability negotiation and call forwarding. This makes it unnecessary to
establish an independent H.245 TCP connection for transmission of H.245 message.
Enabling fast connection and tunneling on the originating GW
Step
1. Enter system view.
2. Enter voice view.
3. Enter voice dial program
view.
4. Enter VoIP voice entity
view.
5. Enable fast connection.
6. Enable the local end to
play ringback tones.
7. Enable tunneling.
Enabling fast connection and tunneling on the terminating GW
You can enable or disable fast connection for each outgoing call on the originating GW. If fast
connection is enabled on the originating GW, the terminating GW will determine whether to enable
fast connection for call initialization or enable tunneling, depending on the configurations of the voip
called-start and voip called-tunnel enable commands.
To enable fast connection and tunneling on the terminating GW:
Step
1. Enter system view.
2. Enter voice view.
3. Enter voice dial program
view.
4. Configure the call
initialization method for the
terminating GW.

Optional.
In the fast connection mode, the remote
end plays ringback tones by default.
This command is available on an H.323
voice entity only after fast connection is
enabled for it.
If you want the local end to play
ringback tones, carry out this command.
Optional.
Disabled by default.
This command is applicable only after
the fast connection is enabled.
