Hello can about this phone only say positive and sing praises ... Many features and is easy and comfortable to hold. Was it easy to install the router, since it is an IP phone. Connection via telephone plant at Eumex possible (We have it so). About FritzBox the port would be possible even on the S0 port but the Speedport W921V this option does not exist.
Function is also fulfilled as well ... (full duplex and echo cancellation). Using the AB on all handsets.
Am fully satisfied with it. Genuine buy recommendation !!!
