What do I need to have to use VoIP?

These requirements must be met for the use of VoIP.

You can use VoIP with every internet connection (DSL, Cable, UMTS, LTE etc.) worldwide if the up-/downstream is at least 80 kbps.

You can call with every telephone if it’s connected to a VoIP compatible router (eg. FRITZ!Box or Speedport). You can also call via a smartphone app, a softphone via PC or an IP phone.

It’s also possible to get a real local phone number. You’ll be available from any phone connection worldwide with this number.
