I agree with all of the criticisms posted here concerning 3CXPhone shortcomings. Another major issue that we are dealing with is user login. In MyPhone any user could log into their extension very simply by ext# and PIN. This was very effective in network environments where users roam from workstation to workstation. In 3CXPhone, we have to "train" all users on how to setup their account and then DELETE it when they leave that workstation because the next user would have access to their extension. It's been a nightmare.
