ATEWAY

ConneXtions gateways route incoming calls to any available H.323 port. 
The NBX system then connects this port to the extension specified during 
port configuration. H.323 ports are configured through the NBX software 
just like line card ports. Selectable extensions are: 

■

Auto Attendant (500)

■

Receptionist’s telephone (usually the lowest numbered extension on 
the system, with a default of 1000 on the SuperStack 3 NBX system or 
100 on the NBX 100 system)

■

Other extensions (each ConneXtions H.323 port can go to a single 
extension)

H.323 calls are usually routed to the Auto Attendant. From there, 
NBX callers can reach internal extensions without operator assistance by 
supplying a 3-digit extension when setting up the call (as the called 
party), or by dialing an extension after the Auto Attendant answers. 
Callers cannot get an outside line through the Auto Attendant because 
dialing 9 normally diverts incoming calls to the name directory.

You can configure H.323 calls to appear to go directly to an internal 
extension by adding a 3-digit extension immediately after the last octet in 
an H.323 IP address. Do not use commas, spaces, or hyphens between 
the IP address and an extension when programming an H.323 speed dial 
number. IP network connections do not incur delays like those that occur 
with analog PSTN connections.

The # sign in this example indicates when the last digit was entered so 
that the Call Processor does not have to wait 4 seconds to determine that 
a caller has no other digits to dial.

The Auto Attendant receives caller ID information from an outside 
caller and passes it to a caller-selected extension. On a telephone, the 
caller ID name and extension (if applicable) appear in brackets to indicate 
that the network has not authenticated the enclosed information.
