Well, I believe on any product (and, probably, even service) there is a 2 week 'money back' guarantee by either provincial or federal legislature. So, at the very least, the hardware unit should be refundable....
But I'm pretty sure Steve & Kris would resolve it - it must be some tech. issue... The only reason I can come up with in which case the tech issue can NOT be resolved is the quality of the internet connection, in which case you might need to switch the provider, which some people might not be open to.
With regards to that, FPL folks, here is a free suggestion: get the note posted on the web site, asking the potential user to test
objectively the quality and 'fitness' of their internet connection for the VoIP service through this applet
http://myvoipspeed.visualware.com/, so that people with crappy Inet do not get misguided. As well as an explicit note for the user to try the free soft-phone service first to test out the
subjective quality of the connection. Not sure how accurate the results of that applet really are (in terms of correlation of the detected jitter and measured quality index to the actual subjective quality), but it did help me A LOT in tuning the QoS properly on my router, so that I can get consistently good quality measures. And at least in my case, I COULD subjectively hear the difference.
