Your Entra ID directory in your phones' contacts
A phone can look a colleague up in Microsoft 365, but it doesn't recognise them when they call. RingSync copies your Entra ID directory into the contacts of iPhones and Android phones, and keeps it up to date. The caller's name shows before you answer.
Why the phone doesn't recognise your colleagues
Your colleagues' records stay in Microsoft 365. iPhone and Android can find them through a search, but they don't check them when the phone rings, so the call shows up as an unknown number.
To get around it, people save the numbers they need by hand, or export their Outlook contacts. Those lists don't keep up with people joining or leaving.
How it's set up
- 01
You connect your directory
From the RingSync dashboard, you link your Entra ID directory. RingSync reads it and cannot change it.
- 02
You choose who gets it
The people or groups you pick get the directory on their phone. From the Pro plan up, you can also limit the synced contacts to some groups.
- 03
Your teams install the app
You send them the download link, or deploy the app from Intune. Each person signs in with their Microsoft account and allows contacts access. The first sync starts right away.
When someone joins or leaves
A new hire appears on their colleagues' phones at the next sync. When you disable the account of someone who leaves, their record disappears the same way. If you remove their access, the directory is erased from their own phone, at the latest the next time they open the app.
Personal contacts are never changed. On iPhone, the directory is kept in a separate group. On Android, RingSync contacts are marked, and only those are updated or removed.
Your records aren't stored on our side
RingSync reads the directory and passes the records to the phones without saving them. We only keep the name and email of people who have a seat, and the sync history. Our servers are in Ireland.
Security and dataCommon questions
How much does it cost?
€9 per person per year on the Starter plan, €15 on Pro, €24 on Business, whatever the phone. The 14-day trial is free and needs no credit card.
Do I need an MDM?
No, the download link is enough. If you use Intune, you can deploy the app from it on iPhone and Android alike.
Do contacts end up in the employee's iCloud or Google account?
RingSync writes them on the phone. Depending on the device settings, iOS or Android may then copy them to the personal account. The documentation covers each case.
Does it work with the Android work profile?
Yes. Installed in the work profile, the app writes the contacts there.
