VVX 601, UC 6.0.0.4796 - how to disable direct IP calls?

[The German]

With the VVX 601, UC 6.0.0.4796, I am getting "ghost calls" from 100 1001 etc. on a regular basis. I don't have a firewall that allows me port restrictions to just the SIP provider and I was wondering where in the settings of the phone these direct IP calls can be disabled? All guides I found when googeling did not address it.

Thanks, I am getting the idea now - I simply expected it to be part of the settings in the phone or the web ui of the phone, but it looks like this requires download/editing/upload of the configuration file, correct?

Hello @The German ,

again I can only quote the Web UI

Oct 20, 2017 Question:Why can I not change every single configuration parameter via the Phone UI or the Web Interface?

Resolution: Only the most common settings can be changed via the Phone UI or the Web Interface. Additional configuration parameters either require a provisioning server as shown => here <= or simply import a configuration file (or unzip FAQ attached example files) and import these via the Web Interface as shown => here <=
