One reason I am keen to use the 3.3V version is that I currently have
for my own office, the 5V version. Since I first installed it, some
remote parties always complain of poor quality phone lines. ie, it is
always the same people that complain, but not everyone complains. It
doesn't seem to matter whether I use an analog phone connected to a
TDM40B, or I use a budgetone, or even a polycom IP 600.
One person suggested that I try swapping to the 3.3V card, as it may
resolve my issue, so, that is firstly what I am using for my customer,
but in-between I will test it for myself and see if it helps.
Also, the 5V version is not approved for use in Australia.

I haven't been able to hear the problem in calls recorded using monitor,
even though the person complained. However, I sent some fax audio files
created from rxfax, to coppice, and he said:
"The audio is quite distorted, and it takes a bit longer for the
adaptive filter to settle than on most data I have looked at. There are
no audio skips, though. This is just more distorted than usual. I think
the next version of spandsp will deal with your problems. This is the
first audio of this nature I have received from a user. Thanks."

So, it would seem that I have something unusual happening, possibly due
to my configuration/telco circuits/something, but I haven't been able to
find anything that really makes any difference.

PS, it is easily tested/re-producible, to the point where I can call
some customers, and they know it is me before they even finish saying
"hello". Usually, they say "hell, oh, hi adam..."
