[asterisk-users] Can I increase DTMF sensitivity?

[Steve Edwards]

I have a client that is complaining that they are having trouble with 
Asterisk not reliably recognizing DTMF from some phones. The calls are 
being delivered by ATT & Qwest over PRI to te410p's with firmware that was 
upgraded about 10 months ago.

Can I tweak the "amplitude" and duration of what Asterisk considers a 
keypress? (I'm in the US if it matters.)

What will happen if I tweak too much?

Can I measure the amplitude and duration of a keypress to help identify 
the phones?

Thanks in advance,
