Yealink MP56 Microsoft Teams Certified handsets do not sync Outlook contacts

We've deployed a number of Yealink MP56 headsets and cannot get Outlook contacts to sync. We've attempted just about everything to force a sync, but it appears as though the handsets only display co...

Hi, I have also tested a few Teams Phones and do not see any personal contacts on the phone. However I found this in the manual of the Audiocodec C450HD

If a user creates a contact within Microsoft Outlook, their information appears under the
People app on the phone screen. Contacts in Microsoft Outlook are available in read-
only mode. While only phone numbers currently appear, users can search on the phone
for contacts and easily call the people they may email or meet with, using Outlook.

Here's the manual: https://www.audiocodes.com/media/15946/c448hd-c450hd-ip-phone-for-microsoft-teams-users-and-administrators-manual-ver-110.pdf

Can someone confirm?

Thanks S

Yes, this is correct. The AudioCodes C450HD resolves contacts and they did sync immediately once the phone has been deployed. The Yealink MP56 has a number of issues, this being on of them. I would stay away from this model, as we've tested the Yealink MP54, and no issues. Haven't gone to the extent of testing the Yealink MP58, but I can imagine for an executive category phone, you get what you pay for. Although the AudioCodes aren't the best aesthetically pleasing phones, they did resolve the majority of our problems we were running into with the Yealink MP56 handsets we deployed. Just to be clear, we did eliminate any potential risks with it being the network or any other external factors.

Also, be sure to purchase the new C450HD handsets. They just recently released a new model TEAMS-C450HDPS-DBW. This includes dual band WiFi, more internal memory and an external power supply.
