I’m not sure at the moment if I should have posted this on Cisco’s site or here, but i figured I would try here.
I was going to use the a new SPA112 to hook it up to our alarm panel, but after I got it connected to our asterisk server I noticed something very strange. The when you place a call with the SPA112 there is always a echo on the other end of the line. Whether or not it’s to a another extension or to a outside line.
No other extensions (Polycom phones and a SPA2102-NA) have this problem. At the moment I’m at a loss on how to fix it or even being to trouble shoot it.
