Uhhhhh, I think that's a serious stretch right here. 

a) realiability of internet router doesn't hold a stick to reliability of 
a proper class 4 or 5 switch.

b) even if you compare to an average PBX (definity or something), it is
much more stable than your router (which can get ddos'd or worse) or your
carrier's IP link (again, ddos, misconfigurations, and in general, it is 
not designed for 100% availability simply because there are more 
"things" the router is doing compared to a stupid PBX). 

Sure, voicemail can be flaky - but at least you can always place calls.

Not quite sure of this one. If they are doing Internet traffic over that 
same T1, they are susceptible to ddos and IP-based attacks on their 
infrastructure and at *your* infrastructure.
