and all the volumes have been initialized.
Usage:
• Execution: AT!AVDTMFVOLDB=<profile>, <generator>, <level>, <value>
Response:
OK
Purpose: Set the audio and DTMF volumes for the specified <profile>.
• Query: AT!AVDTMFVOLDB?<profile>, <generator>, <level>
Response:
<value>
OK
Purpose: Return the current volume (<value>) for the specified
<profile><generator><level> combination.
