D865 Directory not functioning

Hello Snom Community,

We recently purchased a handful of the D865 to replace our old 720s.

After going through the setup and getting the phones into a working order we found that our directory which has members flagged as VIP is using the default ringtone.

Under Preferences → Audio → Directory Ringtones → VIP we have it set to ringtone 5
We've also changed the default ringtone from Ringtone 1 to Ringtone 9 on the D865. All calls the ring in regardless of if they're in the directory or not are ringing as Ringtone 9.
In addition to this all entries into the Directory when receiving a call from a directory number it comes up as "Wireless Caller" and not the entry in the directory.

These two things lead us to believe there is some error with the directory that is making it not function as it has on previous versions of SNOM phones.
Previously on older SNOM phones making an entry in the directory would making any inbound call from that number display as the directory entry. Adding a group to that entry and assigning a ringtone to the group would apply a different ringtone to all of those entries.

I've looked through the XML file and am unable to find anywhere that would control this outside of the base WUI settings.

We're looking to have directory entries be used for the inbound caller ID and assign a ringtone to the directory entries.

Would anyone have any suggestions or solutions to this problem?

Thank you,
Cody
