Your advantage with®® is also a partner in your industry: as an ITC system house, cloud enabler, advertising agency, distributor, software manufacturer and managed service provider.

Know who is calling as soon as the doorbell rings

The fully automatic regular synchronization of your contacts from Microsoft 365 / Exchange with the Placetel phone book means that you can finally recognize the caller's name when there is an incoming call. Finally you can see the caller's name + company in all desk phones, softphones, DECT handsets and more supported by Placetel.

Dialing with a mouse click: real "click to dial"

As soon as your Microsoft 365 contacts (formerly "Office 365") are synchronized with your Placetel phone book, you can easily call them with a mouse click. Save yourself the manual dialing, one or the other typo and avoid so much frustration!

No more double data maintenance

You can finally concentrate on your core business again and not on avoidable, stupid work like maintaining the telephone book. Regular maintenance of contact data in one place (e.g. in Outlook) should be enough.

Two-way sync

If you want,® even synchronizes your contacts in both directions with the Placetel phone book and Microsoft Office 365 or Exchange.  No matter where you edit your contact details, the other app automatically takes them over!® - with security color backgorund.png

No storage of synced contacts:® synchronizes your contacts from one software to the other. The algorithm only saves which "contact references" have already been transferred - but never contact details.
