Just an FYI...
I been using Ascendis for some time and it worked great untill I got rid of Verizon and signed up for Cablevision OptimumVoice.
From that point I was getting about 10% of the caller id information.
I saw on Ascendis website that Jaton Wincomm V.92 seems to work.
So I bought one.
It took 5 minutes to install and has been working GREAT!!
So far out of 165 calls in the past month I did not get callerid info from 2 calls!
