We have several folks who work offsite and use 3CX phone for Windows on their laptops. After installing the latest release these folks have no IM, Presence or Contact information. The phone registers through the tunnel and works fine. It is just when you choose the Presence screen and Contact screen they come up blank. That and you cannot use the IM Feature. They all have the latest version of 3CX Phone for Windows installed. Any help would be appreciated.
