Azure AD does not support multiple phone numbers
Last modified: 2022-04-05 18:02:01 CEST
https://docs.microsoft.com/en-us/azure/active-directory-b2c/user-profile-attributes LDAP attributes telephoneNumber and mobile can contain a list of elements. Azure attributes for those fields expect just strings, not a list of strings, so currently, we are filling it with the first element of the LDAP lists. Look for a way to sync multiple phone numbers if exists.
