Hello Richard, all,
Alerts stopped coming somewhere last summer, but I only got to trying to get things back working now 
I got simple alerts working again, but when using templates as in below message it seems to fail - logs pasted below. The device is a connector to Asterisk PBX that I built years ago. It works fine as far as I can see in other events/actions. Do you have any suggestions? Thanks!
