I tried to setup jabber profile.
I created CSF profile and assigned line to it.
but the user is not able to log in to jabber.
In the end user there is no place to select UC Service Profile.
System Version : 8.6.2
Any help would be appreciated.
You're following documentation for 9.x and later, in 8.6(x) you still had to do a lot of the config on both sides, as it was not centralized in CUCM, you need to configure all the profiles on CUPS and associate to the user.
I found this video on YouTube, I have not watched, but might be able to help you
Aside from that, make sure you review the old 8.6 documentation, which will have no reference to UC Service Profiles.
