Hi Dan, As you mentioned, there are Connection timed out and Connection resets in your logs. Mediasense is seen trying to send the event notification, but if wasn't successful because connectivity, could be firewall. I would advice to check once on the connectivity maybe with your IT team. Further: I tried to run the subscribeToEvents API on my local set up, to see if I could reproduce the issue. I'm getting both the notifications successfully i.e. for call start and call end.
