asterisk users - Jan 2011 - U-verse DTMF tuning for Zaptel

One of my clients is complaining that their customers that use U-verse 
(and other cable providers) for telephone service cannot enter credit card 
numbers reliably.

The issue not all digits are received in my dialplan.

The calls come in on PRI.

It's an old 1.2 install, so the only tweak available is 'relaxdtmf.'

Any clues on how to proceed?

Would jumping to 1.6 help?

Thanks in advance,

Can you record a few calls just to confirm the problem?

I've had 'dtmf issues' that really were cases of people entering
data
during recordings rather than at the appropriate time in the prompts.
