Entering Digits
During Calls
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.
Receiving Calls
ConneXtions gateways route incoming calls to any available H.323 port.
The system then connects this port to the extension specified during port
