Hi Chris,
I checked the provided logs and noticed that the request is coming without any instrument.
15:29:20:574 cg1A-ctisvr Session 9: MsgType:QUERY_AGENT_STATE_REQ (InvokeID:0x3 PeripheralID:1 MRDID:1 ICMAgentID:0 AgentExtension:""
15:29:20:574 cg1A-ctisvr Session 9: AgentIDLong:"3100" AgentInstrument:"" )
You should not send the request without agent extension/device details. If you check the CTI server message ref. guide for the same message, you can see following mentioned:
Please add right extension details in the request.
