This object specifies the duration of the pause after an
active DTMF digit during DTMF playout from the gateway.
For playout of multiple DTMF digits, the sum of the
digit-on and pause (signaling velocity) should not be
shorter than the time specified in Q.23, Q.24 and
EIA/TIA-464. For example, 93ms/digit for AT&T,
120ms/digit for NTT, 100ms/digit for Danish
Administration.
