Is the dialplan context [queuemetrics] included?
If it’s not included, you can find the example file extensions_queuemetrics.conf under QueueMetrics’ own README directory – just copy that to /etc/asterisk and #include it in the main dialplan (note: you should review that file before inclusion as it should be customized to fit your environment). • Are you seeing connection attempts? If you open the Asterisk CLI, you should see a message when QM connects and disconnects. If you see nothing, there is some setup error (e.g. a firewall) that prevents QM to connect to Asterisk.
