[Asterisk-Users] Digits being dropping when dialing from certain analog phones

[James Bean]

FC2, Asterisk 1.0.0, Zaptel 1.0.0
TDM400P Port 1 FXS Port 4 FXO

Standard analogue handset plugged in with pstn line.

Problem:

I have 2 analog phones that I use, when plugged directly into pstn line
both phones work perfectly, dialing no issues. When I plug the handsets
into the TDM400P, one works perfectly the other drops random numbers.
Its like the tone is slightly different on the second handset and its
not picking up some numbers (1235&6 it seems). Is there a way to adjust
the tone detection, make it more sensitive?

Keys dialed from handset were

9 0418800185

I tried hitting the keys slowly as well as at my normal speed, all tones
are heard in the handset for all numbers.
