How can I uninstall Net2Phone SIP Dialer?
To uninstall this software you can follow the instructions provided in the user guide by Net2Phone Inc, the developer of the product.
Also you can try to use some uninstallers like: Revo Uninstaller, IObit Uninstaller, Advanced Uninstaller Pro or Absolute Uninstaller. All of them are free of charge but I recommend you to use Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
