Avaya's latest softphone (one-x) is a software package which needs to be installed on machine. Has there been a solution where
1. Has there been a solution from Avaya where Softphone interface has been web-based and One-x (Or any other softphone implementation from Avaya) doesnt have to be installed on machine?
2. This web interface terminates voice call on the desktop using a different voice client (Say google voice)

3. Can we implement a solution where we don't need Avaya softphone client, we just develop a local softphone client which replaces Avaya one-x and still registers with switch?
