[VoIP] Tone duration

[John Novack]

One of you smart Asterisk guys know where in Zaptel the DURATION of a 
specific DTMF pair is controlled?
One of the Cnet guys is having trouble with misdialing in DTMF to his 
step switch, and we'd like to extend the duration of each digit dialed.
The switch doesn't mis dial from a butt set, but Asterisk does.

I will be installing the latest Zaptel and Asterisk first, so this needs 
to be changed in 1.2.16

TIA
