I got a ton of Cisco 7960 series with 48v powwer brick that are usually set up as SCCP but they WILL do SIP , most all I have I converted to SIP. I used them with asterisk , they will also do POE. They are not the latest. Drop me a line I don't want much for one , they go for stupid prices on ebay, seriously I got like 40 or more and they do work. I can hook you up, where are you located, they don't weight much so shipping would not be too much.
