 From my experience, the ATA is a very solid, dependable piece of 
hardware. I was told by a source in the company that OEMs for Cisco, the 
units are expensive because of the high quality parts being used. The 
web config looks crappy but otherwise where else do you find a $100 
device that does SCCP/MGCP/SIP/H323? None of the competitors even come 
close to that level of protocol support. For developers who have to work 
on various protocols, the ATA is really cool.

And, the ATA is relatively easily to port forward on the firewall. Just 
1 SIP + 8 RTP ports, compared to the recommended 2 SIP + 10000 (ten 
thousand) RTP ports  + 2 misc ports for the Sipura.

Documentation for the ATA is really good - the usual Cisco standards. 
Most of the competitors ship with simple manuals that come nowhere close.

I have an SPA3000. The configuration is very comprehensive but the 
documentation (the 90+ page version) is not as well written as the ATA.
