QRT Softkey isnt work (Service is not available)

[delr]

Hello Cisco Community. I write to you asking your help regarding the configuration of the QRT feature in my C7942 and CIPC , using my CUCM version  8.6.2.20000-2 (Running on Demo Licenses). Ocurrs that, when I press the QRT softkey in both phones, apears the message "Service is not available"

I summarize the steps that I followed since the last week:

1) I followed the steps of the document: http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/7_1_2/ccmfeat/fsgd-712-cm/fsqrt.html#wp1220178

2) I restarted the CEF services and activated the CTI Manager service according to the following discussions:

https://supportforums.cisco.com/document/14441/when-user-presses-call-back-or-qrt-softkey-after-configuring-call-back-or-qrt-cisco

(but the bug CSCec32073 is for CM v4.0 and suposed fixed in later releases, and I dont understand how to reset the CCMSysUser in CUCM 8.0)

Hello Cisco Community, finally I was able to solve this issue by myself. The key is save the service parameter configuration for CEF service, even you leave all the options as default, and activate the Cisco CTIManager service.
