Can you try this:
- Go to CAD Admin web page
- Services Configuration-> Remove VoIP/Recording & Playback Services
Make sure that there are no IP addresses of any servers in the Recording & Playback Service menu. If there are some, select them and press ‘Remove’ button to remove them.
Please make sure that you close CSD, CAD completely and login back to see the changes. I haven’t tried this before but I think this would disable the recording buttons in CSD. I don’t know whether it needs CAD services restarts(all).
