I must say, they really are among the most stable and featureful I've 
run into.  There are lots of other options - and I can hardly claim to 
have sampled a vast diversity - but the common thread I've run into 
with other equipment is bugginess, SIP interoperability and DSP issues.

I don't know the grounds for your objection to them, but I can tell 
you they are quite ubiquitous inside carrier environments for a reason.

It's hard to say how the 5300 compares to a router outfitted with 
voice cards;  it depends on many things, including the processing 
power needed for the intended application.  It's definitely more 
powerful CPU-wise than a 2800, though.  Can anyone else on the list 
speak more to the precise feature set differences?

I'd get a 5300.
