Recording a Handset Conversation on the Phone Line
To recording a handset conversation on the phone line, issue:
AT#VLS=8 (valid after Voice On-line mode)
This command engages the Caller ID relay to allow recording of conversation when using a handset by routing the signal to
the audio codec (if populated).
To deactivate the Caller ID relay, the host should issue an AT#VLS=0 or AT#VLS=6 to return to phone line or speakerphone
mode, respectively.
Recording/Playback from Handset through Sound Chip
To recording/playback from the handset through a sound chip (valid after voice on-line mode), issue:
AT#VLS=9
This command routes the handset to the sound codec to allow recording/playback of audio (e.g. greeting messages) through
the local handset.
