What do I need to have to use 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.
