Disabled DTMF.
D4
Transmit
DTMF
1
Activates DTMF. The selected DTMF tones are
transmitted continuously when this bit is high. TX DTMF
overrides all other transmit functions.
0
Disables answer tone generator.
D5
Transmit
Answer Tone
1
Enables answer tone generator. A 2100 Hz answer tone
will be transmitted continuously when the transmit enable
bit is set. The device must be in Answer mode.
