It seems to me that your data rate is abitrarily low. If you could get
a higher oubound data rate you'd have better results on average. I
switchedmy home office ADLS from 1.5M/384k to 3.0M/768k and the impact
was huge.

There certainly are mid-market SIP phones available. I'm enamoured of
my Polycom IP600, but the IP300 & 500 are less than $200 each. Avoiding
FXOs entirely will eliminate a major headache. I think that the
availability of business class features on SIP phones is worth more
than the slight cost savings you might achieve using ATAs with analog
phones.

Polycom IP300 = $140
Polycom IP500 = $210

I'd be inclined to build an embedded Asterisk for the remote location
and trunk back to your main office. You can also setup an account with
an ITSP like Sixtel.net or Voipjet and place outgoing calls directly
from the remote server.
