Start the feature by touching Incoming calls in the menu
You will then see a list of incoming call numbers.
If the caller is in your phonebook, the name will be in addition to the number. It may also be a person whose number is known by Avista’s system without being registered on your phone.
By touching one of the numbers on the display, you will find out if the caller is registered as a contact person in the system.
If it’s a contact for any customer you have visited you will get information about it.
