3 out of 5 eggsgot it!

Pros: Good construction, not cheap feeling, similar to the high end CISCO phones. Supports all the SIP features you need and then some. Works well with Asterisk.

Cons: The Packaging was not complete as it did not contain the power supply that was supposed to be included with the phone. I am working with NEWEGG to get a power supply sent.
