asterisk users - Aug 2004 - Autoattend detecting same digit twice

All,

Has anyone ever seen a problem where the autoattend detects the first digit
twice?

What I am seeing is this:

My extensions are 421-468.

When a caller calls in and dials exten 433 from the autoattendant,  they get 
exten 443. This is happen for any extension that is valid in the 44x range (i.e.
42x -> 442, 43x -> 443, 44x -> 444, etc.).  I am seeing this problem
about 1/3 of the time.

My setup is 6 PSTN (POTS) lines -> AccessBankII channel bank -> T100P card
on the asterisk server -> Cisco 7940's and 7960's.

I have been through the wiki and the archives, but haven't found anything
yet. Any pointers would be greatly appriciated.

TIA,
Kenny

Yes, I have seen the same behaviour. In my case it seems to be less than 
perfect dtmf tones. They are detected, but sometimes a very short break in 
the middle of a tone causes Asterisk to treat the rest of the tone as a 
new digit.

Not even the relaxdtmf has helped. I have access to a set of phones that 
triggers this behaviour. I'll submit a bug as soon as I have recorded the 
tones from within Asterisk.
