Resolution
You can add user accounts on the Cisco CallManager server for clients running Cisco IP SoftPhone to log in on. When a SoftPhone client logs in, the username and password configured on the Cisco IP SoftPhone must match exactly what is configured on the Cisco CallManager server.
For a step-by-step procedure on how to add each Cisco IP SoftPhone user to the Cisco CallManager administration pages, refer to Adding Cisco IP SoftPhone Users.
