I'll have to test it, but they say:

# Up to 1 Mbps download speed
# Up to 256 Kbps upload speed 

So, since the tech says it's operating within parameters, it should work. 
However, I take that with a grain of salt.

I thought it was storms, then it was random, but, yeah, could've been humidity.

Is it somewhat expected that skype would work acceptably where SIP cannot?  Of
course, I'll continue working on SIP.
