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.

one way to be sure its working ok is to use a router that can do QOS. (quality of service)
If you program the router properly it will assign a part of the bandwith to the ip adress and/or the ip port used for the voip device.
One way to have QOS for cheap is using dd-wrt as the firmware of your router.
on my side I use a buffallo router model whr-hp-g54
even have a strong wifi signal..
