7.6.4.2. Interrupted Answer – OGM Playback with DTMF Menu Entry
The procedure listed in Table 132 uses a remote-access password of 1234. DTMF decoding is asynchronous. The
host voice driver will need to employ a timer or timestamp to validate the consecutive DTMF digits that comprise
the remote password.

Ring Detection
Play local ring tone.
Receive Type I CID DLE complex report.
Ring Detection.
Play local ring tone.
Ring Detection. The voice driver will use a
rings-to-answer count. This example uses
three rings before answer.
Play local ring tone.
Mute the speaker so the OGM is not heard
locally. The user may remove this com-
mand to allow local review.
Set the DAA-to-RS232 receive gain regis-
ter (UBF) for TAM PSTN.
Disable DAA-to-Si3000 receive gain path.
This ensures line events such as CID and
ring tone are not heard via the codec.
Mute the microphone.
Enable speaker for local ring tone/alert
tones.
Disable voice mode. Used as a transition
point between non-zero +VLS voice
modes. This will hang-up the call.
Setup on-hook TAM voice mode. See
