cisco VOIP phone logout services not available

sometime The login process works fine, when press the service button and then it asks me for userid and pin, if the authentication is successful the device profile that you set above is loaded into the phone, the problem is when you try to do a logout that profile on the phone, when you try to do a logout and press the service button, you get the following message "No services configured".

Do subscriber service on the profile, you go to CUCM Admin > Device > Device Settings > Device Profile.  Click on the EM profile.  Then use "Related Links" on upper-right hand corner to subscriber EM services.
