We get the active call from the CallEvent (https://downloads.avaya.com/elmodocs2/AES/4.2/javax/telephony/CallEvent.html) object
and we map to the Call object - LucentV7CallInfo (https://downloads.avaya.com/elmodocs2/AES/3.1.1/jtapi/com/avaya/jtapi/tsapi/LucentV7CallInfo.html).

LucentV7CallInfo callInfo = (LucentV7CallInfo) callEvent.getCall();

But we are wondering if we can get the stationId from either the callEvent or the call object?

Version of ecsjtapia.jar is below.

Get connection object from event and from that you will get station address.
Should be event.getConnection().getAddress().getName()
