The Internet dialog box contains the following parameters:

Lucent Gateway 
Protocol

■

Signaling Port: Displays the initial port number (5000) used for 
call setup. Display only.

■

Setup Time-out (ms): Allows you to set the number of 
milliseconds to wait before canceling a call attempt while trying 
to set up the Internet connection.

If the call setup exceeds this threshold, the calling party will hear 
a fast busy signal. The call setup time probes network traffic 
conditions at the given instant. Exceeding the set threshold 
indicates that the network is congested and that good voice 
quality may not be possible on the Internet. Setting this 
parameter to a large value effectively lets all calls go through 
regardless of Internet traffic conditions. Setting this parameter 
too low unnecessarily restricts otherwise good calls. Generally, 
you should accept the default value of 8000. 
Valid values: 

 to 

■

Keep Alive (sec): Allows you to set the number of seconds to 
wait before clearing a call if the remote switch does not respond.

Valid values: 

 to 

. It is recommend that you use the default 

value (30 seconds).

H.323 Protocol

■

Signaling Port: Displays the initial port number (1720) used for 
H.323 call setup. Display-only. 

■

Setup Time-out (ms): Specifies the number of milliseconds to 
wait before canceling a call attempt while trying to set up the 
H.323 connection. Display-only. 

■

Keep Alive (sec): Allows you to set the number of seconds to 
wait before clearing an H.323 call if no voice traffic is detected. 
Valid values: 

 to 

.

Enable GateKeeper

Uses the gatekeeper subsystem of the DEFINITY ECS application to 
assist in H.323 dialing, rather than dialing directly. Display -only. 

Port

Displays the initial port number (1719) that gatekeeper uses for 
H.323 call setup. Display-only.

Setup Time-out 
(ms)

Specifies the number of milliseconds to wait before canceling a call 
attempt while trying to set up the H.323 connection using gatekeeper. 
Display-only. 

IP Address

Specifies the IP address of gatekeeper. Display-only.
