I have a client who we just upgraded from 3cx v9 on win 2k8 to 3cx v10 on win7 pro x64. All works great except the phonebook. We're using Yealink Sip-t28p & sip-t20p phones. When you click on phonebook it says "loading" then just errors out. I've tried unplugging the phone & replugging it back in, so it will reprovision, but to no avail. Anyone know how to get the phone book back?
