Host-Based Controller Modem
AT Command Set

AT Voice Commands Reference

AT+FCLASS=8
The command AT+FCLASS=8 puts the modem in voice mode. Speakerphone and TAD modes are subsumed
under the more general heading of voice mode, and use a particular subset of voice mode commands to
implement their respective features and functions.
The modem controller will maintain the overall state of the system so as to know when voice commands are
issued in the context of using the speakerphone versus TAD or other voice contexts.
