11.2.8 +VTS, Command-Specific Tone Duration

This command transmits a string of DTMF tones when a voice call is active. DTMF tones may be used, for
example, when announcing the start of a recording period. The duration does not erase the VTD duration.
Note: In GSM, the tone duration value can be modified depending on the specific network.
If the active call is dropped in the middle of playing a DTMF tone, the following unsolicited message
transfers to TE: +VTS: "Call termination stopped DTMF tones transmission".
