Correct, but I've also seen many reports that replacing the power cube of 
the IAXy with one that can provide ample power did solve the problems and 
even resurrected 'dead' IAXY's. On the temp : I guess you're talking 
Fahrenheit, at 80-90 degrees Celsius I'd be really worried :) But it's 
still too hot to my liking, the lifetime of many components isn't 
prolonged by such temperatures. I also do create groups of Sipura's where 
I have 4-5 units on a shelf (because it is 1/3 of the price tag of a real 
solution) and then a lot of heat is dissipated.

Agreed, but the IAXy was intended to be a general purpose ATA, for 
applications like this the cost is nothing.

Ever since I switched from cable to DSL uptime has been great but there 
are just more single points of failure for a VOIP connection. I'm just 
waiting for SIP GSM bridges to become available for a nominal fee, that 
really makes an ideal bakcup line for alarm and phone systems. A SIP 
device can be had for the price of a hamburger and a cell phone for the 
price of the coke to come with it. Too bad a combination of the two is 
priced around USD 1500 (and I don't want a bridge with POTS).
