FYI

There are sevral kinds of alerting events and here is information how to detect cause of forward and transfer.
Here calling sequence is as follows: 09065XXXXXX(caller)-->05030XXXXXX(topic number)-->5706(VDN)-->5003(extension number)--(forward/ConsultCall)-->5004(Alerting/Ringing)
Currently we are monitoring all extension numbers and VDNs by CallControlConnectionListener.
