Can you confirm that on this specific DN you have enabled all the "Name Information" fields such as, "Alerting Name", "Display (Caller ID)"?
Thanks for your feedback,
I am almost sure that the X is the first Letter of Xiaoxia.Jia, so for the sake of clarify, try to change the 3 fields that you've mentioned for example to "George Sotiropoulos", I believe you will see next to the number "GS" instead of "X"
Thanks for your reply, but the customer has replaced anothe phone, it's ok , and he has not test to change that 3 label text.
In the future, if he test that I will update here.
