What you'll see is how well the device works on your home/office line at the
time of testing.

Unfortunately since its Voip and subject to the same issues as any other
Voip service it won't tell you much about how it will perform in the field
tomorrow, next week or next month.

Other than using it for voice, fax and possibly using it for downloading I'm
not sure what attraction this device holds for anyone in the alarm industry,
if the customer has no land line and has broadband then they probably
already have Voip of some sort and liability wise you would probably be
better off using their Voip (with a suitable disclaimer), rather than you
providing or recommending a Voip device for them to use.

If they have no land line or Voip but have broadband, then in my opinion you
would be better off using an IP communicator.

With the low cost of cellular devices and the low monthly rates available I
prefer to use cellular for backup for those customers who choose to use Voip
for their alarm service.
