The tilde character (~) in front of a contact name indicates that the name displayed is a nickname (e.g. “~Bob”). A user can choose any nickname, and it might not correspond to the actual name of said user (e.g. “Robert Smith”).
In the following cases, the tilde is not displayed:
You define the first and last name of users using your administrator privileges (via configuration settings or in the contact list that you provide through the management cockpit).
Contact synchronization is enabled, and the ID matches an email address and/or telephone number of a contact stored in the local address book. In this case, the contact list will show the name stored in the local address book instead of the nickname.
The user entered the name manually in the contact details in the app. In this case, the contact’s name is displayed, not the nickname.
