I have a very strange phone... If I all ready have a conversation and another phone call me, the number two call do not get the busy sound, but only the normal calling voice, as when you call another phone number.
In our "Cisco Unified CM Administration - System version 188.8.131.5200-2", I have looked in every setting for my "CISCO IP Phone 7940 series", but I can not see any errors in the configurations...
I have attached a .pdf file 1595 configuration.pdf with 3 screendumps of the "Phone configuration" page, the "Directory Number Configuration" page and the "Edit Line Apperance" page.
Can you help me locate the error?
