I use the rest interface in C# to send commands to IP office.

When I receive events back, sometimes (often) there is no client session ID in the first event collection I get.

How to fix that problem? I thought about calling a get telephony presence, and setting it to the same value afterwards to force it to trigger the first event.

I know there is some sort of other forum, but that is behind a paywall where I need some sort of ID which I don't have, so please don't refer me to that.

Edit:
If I did that, I receive two telephonyPresence events. The first has no client session id, but another one arrive 11 seconds later which does, and we're good to go. Not the prettiest solution - I hope someone has the *right* one
