Voice Commands: Telephone Answering Device (TAD)

+VLS=?—Analog Source/Destination Selection and DTMF/Tone Reporting
Requests for the modem's DTMF/tone reporting capabilities are made using this command. For each
system configuration in voice mode (i.e., speakerphone and answering machine), the modem reports the
capabilities that are enabled for the configuration.
For each configuration, the modem indicates tone-reporting capabilities for each of the three different voice
states: voice transmit data, voice receive data, and voice command state (voice idle).
TAD supports each of the following ITU-T Recommendation V.253 analog source/destination
configurations.
