Right now push does not seem to work anymore. I have it enabled on my phone but I no longer see a connection from push server to my PBX when phone goes to sleep. Please advise.

I reset the application but erasing all data, then entered my PBX credentials, selected "exit, notify of new calls". Several hours later push sever correctly responded on incoming call but phone never woke up. Started application, looked at the log, it contained perfectly valid EVENT lines, related to push server.
Then I disabled log, waited several minutes until application went into sleep and no push server connected to PBX.
I suppose I can reset and try the same sequence again...

There are just too many lines with private information. I'd like to upload log to an editor, clean and then send out.

I am seeing lines

EVENT, check presense for:,NNN,NNN,NNN,...
and
EVENT, parameter presenseuserlist=,NNN,NNN,NNN,...

which list all numbers I ever dialed, as well as

EVENT, parameter blockedpresenseuserlists=,NNN,NNN,...

some more numbers

regardless of logs, is presence query configurable? my PBX does not support it anyway.
please remind where I can read about above features.
