At present you can't see the registration status of trunks in the new panel. We will add this in future. However, there are emails sent to you automatically when a trunk gets down/up again for monitoring.
Personally I much prefer the old status screen where I could see my whole pbx at one glance. This seems of more use to those who are actively managing the pbx functions, not for me who just checks status of extensions and trunks maybe once per day.
The issue for me is firstly that I cannot see the status of all extensions and trunks at the same time, and secondly the information is not presented on a single screen but I have to scroll down.
Personally all I require is a simple single glance technical status display that shows me the registration status of my PBX. I do understand that others may have use for other functions relating to call centre type information.
