Today my home network had quite a few problems.
First Vodafone’s station decided that for my VOIP line was ok to abandon me in the middle of a conference call.
It turned out that it was not a temporary issue: the interface was reporting that everything was ok yet I was unable to place or receive other calls.

The hiccup of Vodafone’s device also got my dual wan router confused: even having a second WAN line working fine I was no longer able to access the internet.

I felt positive about the VF Station so I have reset everything else first: the PSTN+VOIP phone (Siemens Gigaset A580IP), the dual wan router (Netgear FVS336Gv2) and the network interface on the notebook

At the end pf the troubleshooting a physical power off of the station was needed to bring the service back.
Quite inconvenient as the device is located in a cabinet and not readily accessible and it’s not the fist time this happened to me.
