We tested PICKUP today as follows:
1) phone5005-->phone5004
terminalConnectionRinging()
printCallControlTerminalConnectionEvent() CallControlTerminalConnectionEvent.CALLCTL_TERMINAL_CONNECTION_RINGING
Event.CAUSE_NORMAL (100)
UCID = 00032094781666254237
TsapiCallID = 6636
callingAddress = 5005
CCTerminalConnState = TALKING (98)
calledAddress = 5004
CCTerminalConnState = RINGING (97)
lastRedirectedAddress = null

2) phone5003 PICKUP
connectionDisconnected()
printCallControlConnectionEvent() CallControlConnectionEvent.CALLCTL_CONNECTION_DISCONNECTED
CallControlEvent.CAUSE_REDIRECTED (210)
Event.CAUSE_NORMAL (100)
UCID = 00032094781666254237
TsapiCallID = 6636
callingAddress = 5005
CCTerminalConnState = TALKING (98)
calledAddress = 5004
CCTerminalConnState = null (=terms[0].getTerminalConnections())
lastRedirectedAddress = 5004
CCTerminalConnState = null (=terms[0].getTerminalConnections())
Old CallID = 6636, DeviceIDType = 0
Old DeviceID = 5004, Cause = EC_REDIRECTED (28)

terminalConnectionDropped()
printCallControlTerminalConnectionEvent() CallControlTerminalConnectionEvent.CALLCTL_TERMINAL_CONNECTION_DROPPED
Event.CAUSE_NORMAL (100)
UCID = 00032094791666254245
TsapiCallID = 6638
callingAddress = null
calledAddress = null
lastRedirectedAddress = null
Old CallID = 6638, DeviceIDType = 0
Old DeviceID = 5003, Cause = EC_NONE (-1)

terminalConnectionTalking()
printCallControlTerminalConnectionEvent() CallControlTerminalConnectionEvent.CALLCTL_TERMINAL_CONNECTION_TALKING
Event.CAUSE_NORMAL (100)
UCID = 00032094781666254237
TsapiCallID = 6636
callingAddress = 5005
CCTerminalConnState = TALKING (98)
calledAddress = 5004
CCTerminalConnState = null (=terms[0].getTerminalConnections())
lastRedirectedAddress = 5004
CCTerminalConnState = null (=terms[0].getTerminalConnections())
Old CallID = 6636, DeviceIDType = 0
Old DeviceID = 5004, Cause = EC_REDIRECTED (28)

5004, Cause = EC_REDIRECTED looks OK. But there is no TALKING between 5005 and 5003 which picks up a call.
