I'm trying to use the event socket to determine whether and extension is engaged.

Has anyone already skinned this cat?

I don't really want to query I want to take an event and stick it somewhere. At the moment the best bet seems to take any PRESENCE_IN event and then update using that.

If we were dealing with purely non-call waiting situation then I could just set the extension to available status when we have received a state 'terminated' from the event. With call waiting this is no good as we need to know whether there are multiple calls. I think there may always be a 'ringing' state so I could use that to increment an extensions call count but its possible we may receive multiple ringing events for a single call without a terminated in between.

Any help is welcome :)

Actually, it looks like the RINGING, that I was looking at is not a reliable state, I was using Channel-Call-State but that shows ringing even though it appeasrs now answered. It looks like Answer-State or status would be more reliable.:

I'm subscribing to CHANNEL_HANGUP_COMPLETE and CHANNEL_ANSWER events to get that information, but I'm not dealing with call waiting in my small environment.
