Fax Talk NetOnHold 1.5

[Dot]

I have Fax Talk NetOnHold 1.5 and it won't work at all. I tried Phone Tray 2.27 and only one of its features will work. It will not give me the name & number of the incoming call. I get this message, Your modem couldn't establish v.92 connection Some modems can detect incoming calls only with v.92 connection. My ISP connection is v.90. What in the world can I do to get the Fax Talk to work? I don't like Windows Vista.
