We maintain two sets of documentation. This is silly. http://community.kde.org/Real-Time_Communication_and_Collaboration/Troubleshooting#TroubleShooting and http://userbase.kde.org/Telepathy Though we don't really want to have userbase covered in "you've installed it wrong" as most people will be using packages. Maybe talk to Anne Wilson/userbase team about what should be there.
Thank you for the bug report. As this report hasn't seen any changes in 5 years or more, we ask if you can please confirm that the issue still persists. If this bug is no longer persisting or relevant please change the status to resolved.
Dear user, unfortunately Telepathy is no longer maintained. Please migrate to another solution, e.g. for Jabber a possibility is Kaidan, for Matrix a candidate is NeoChat.
