IP-PBX (Hardware)

If you have an IP connection from Deutsche Telekom it is recommended to network a Fritzbox with your provider to e.g. connect the Telpho PBX or Yeastar MyPBX via SIP Trunk to a FritzBox. What used to be the ISDN or Analog Port is now the FritzBox that provides your network connection.
For example, a current AVM FritzBox (as of 02/2019) supports up to 8 call numbers or SIP clients and the FRITZ!Box 7390 allows you to make 5 or with the FRITZ!Box 7580 / 7590 up to 8 calls via the Internet. For exact details please contact AVM.
