Usage
Expect digits from either in-band or out-of-band, but not
simultaneously. The server allocates a DTMF receiver
whenever it needs to collect digits. This option normally
would be used for EC500 XMOBILE station calls.
Expect all digits to be delivered by out-of-band signaling
only. The server running Avaya Communication
Manager collects digits that it needs from the
out-of-band channel (no touch-tone receiver). In
addition, any digits received when the server is not
collecting digits are converted to DTMF and broadcast
to all parties on the call. This option is in force for DECT
XMOBILE station calls.
Expect all subsequent digits to be delivered by
simultaneous in-band and out-of-band signaling.
Out-of-band signaling consists of digits embedded in
ISDN INFO messages while the in-band signaling
consists of DTMF in the voice path. The server running
Communication Manager collects all digits that it needs
from the out-of-band channel. No touch tone receive is
allocated in order to prevent collecting double digits.
End-to-end signaling occurs transparently to the server
via in-band transmission of DTMF. This option is in
force for PHS XMOBILE station calls.
