EM is an IP Phone service. It applies user specific device profiles to the phone after login. Administrators have 3 options to set system behavior if a user logs into multiple phones concurrently.

  • Allow multiple logins – User can be logged into multiple phones at the same time. Has a shared line effect. All phones will ring when the DN is called
  • Deny Login – Users can only log into one device at a time. Will receive error message, must log out of other phone first
  • Auto Logout – User can only be log into one device at a time. First device will be logged out of after successfully logging into second phone

When no user is logged into the phone a device profile can be applied (logout device profile).
