We've recently deployed BT Cloud voice and are experiencing an odd issue with some, but not all handsets.
Handsets are Yealink T46U VDM
I've set up company contacts via Sites -> Features -> Company Contacts and it works for some users but not all.
For example, pressing the Directory button on my phone shows the directory as expected. This is the case for most phones.
However, when pressing that on some phones it says "Unable to download remote phonebook". I've tried resetting those phones and re-provisioning them but same issue persists. The phones work fine though and can make calls both internally and externally.
Any ideas?
