5 Verify the one-button dial feature operation by pressing the new button
and confirming that it dials the specified number.
When ConneXtions dials a call, it stores the dialed digits until it connects
the call. Then it sends those digits, and any subsequent digits, to the
remote H.323 device if the device supports version 2, or later, of the
H.323 standard.
The behavior of ConneXtions depends on when the # sign is entered
during this process.
ConneXtions sends digits as messages, which are more reliable than
audio tones. ConneXtions also expects to receive digits from H.323
devices in the same way, and therefore does not have a tone detector.
This means older (H.323 version 1) devices cannot send or receive digits
to or from ConneXtions. For example, the current version of Microsoft
NetMeeting, which sends DTMF tones in the audio stream (in-band
signaling), cannot use DTMF signaling to pass the Auto Attendant.
In instances where other devices might listen for in-band DTMF signaling,
the quality of the tone recognition depends on the selected voice
compression. Tones transmitted by G.711 can be reproduced, but tones
transmitted by G.723.1 are degraded.
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. Default:
NBX V3000 system: 1000
SuperStack 3 NBX system: 1000
NBX 100 system: 100
Other extensions (each ConneXtions H.323 port can go to a single
extension)
