Unfortunately inode delayed the activation of my telephone number for a week without explanation, from their shop’s progress tracker it looks like they didn’t receive a report from the TA technician and/or forgot to send a notification to Etel.
So i had a couple of spare time today reserved for configuring the telephone system.
I spent the time moving my shell- and secondary DNS/Mailserver to the new flat, which is next to moving the firewall the most difficult part of the transition.
