Use your cell phone as a DECT phone - how it works

If you want to use your cell phone to make a call over the landline, you can use it as a replacement for a DECT phone. We'll show you the options.

Instructions: Use your cell phone as a DECT phone

• To do this, however, you need a router that supports IP telephony. In addition, the manufacturer must offer an appropriate app that is also compatible with your router.
• If you use a reasonably up-to-date Speedport from Telekom or a FritzBox, chances are good. Calls from your landline connection to your smartphone land via the respective app.
• We explain in detail how this works in this practical tip. If you use a FritzBox, you will need these instructions for setting up the app.
