Correct, the ADDMEMBER (in standard asterisk) does not provide that, but I can make it.
Our call centres use the QueueMetrics "Log on" and "Log off" buttons to login to the queues. This provides a field for the extention number - which we use to support hot-desking. From time to time agents put the wrong thing in there. I would like what they put in there to show up on the RealTime screen.
I have put information into queue_log in an attempt to make QueueMetrics display the extension (e.g. update queue_log set data1="1234" where verb="ADDMEMBER"). After executing this, the Extension column is still blank.
I see this as an added piece of management information and would like to try and get it working.
