MrNitch,
A Device Type inside of the system is not something the average person or even certified technician would know about.
It looks as though calls are coming into Node 10 from CO Trunk Group 92001 across three different Trunks, 94000-94002.
They are set to ring Extensions 12513, 12803, 12802, and 12301.
Now when you see the Device Type = DEV 303 for example that is a number that is behind the scenes to determine what type of Device that is; such as a particular phone type or a mailbox. A technician wouldn't have access to that information to explain it to you.
Do you see all of the calls this way or only the ones that show up as unanswerable with an IC ring pattern?
Thanks,
TE
