Are we communicating with Pilot2ATC over the Internet?

[Lon33 4]

When we talk with P2A controllers, are we communicating over the Internet with a central P2A server, or are we talking to software that's installed on our own computers? I ask, because usually I get immediate responses from P2A controllers. But sometimes, the controller's response is very delayed. Indeed, sometimes, I get no response at all -- not even from a controller with whom I've already had two-way communication. For example, this morning (a Sunday) on a VFR flight, I was handed off to a new controller on a new frequency. I checked in with my call sign and altitude, and got an immediate response. A few minutes later, though, I advised the controller that I was changing altitudes and got no response at all. I waited a short time, and requested an altitude change, and again got no response. Finally, I simply checked in by saying "Center" and my call sign. ATC usually responds to that kind of check-in with "[my call sign]. Go ahead." But this morning, I got no response at all. So I'm wondering whether we're communicating over the Internet with a central server rather than our own computers, and the occasional delay or non-response is because the Internet or the server is unusually busy.

All voice interaction is done locally, no internet involved.

Could be an error caused the program to stop responding.  When that happens, you can usually get things running again by:

1. Disconnect from the SIM
2.  Reconnect and File the Flight Plan again
3.  Do the initial check in with the controller you were with before the disconnect

Make sure the SIM is not paused when you reconnect, file and check in.

Thanks for your amazingly quick response on a Sunday, no less. Great product. Great support.
