I am new to vitalpbx but have been working with in the ip pbx space for the better part of 10 years. I think vitalpbx is great. GUI looks great, nice and lightweight, easy to manage, and a very simple install process. Great work!
I think the Geo Firewall feature will be a great addition to all my installs, however I have a suggestion for future versions. Perhaps you could build in the functionality of instead of selecting the countries that are not allowed to access the pbx, perhaps you could have the option to do the reverse. Prevent ALL countries except the ones that ARE allowed to access the pbx.
