Thanks for the answer. Unfortunately, this is becoming an issue. We are getting a lot of calls by users that are confused. Not sure why 3CX does not give reseller the option to hide this as we are the first point of contact for our customers. It's as if 3CX wants to undermine and undercut their own resellers. We met with a large customer with 150+ users and their admin said that they do not want their users to be clicking and going all over. They internally did not want to deal with this. Unfortunately, we are looking for an alternate software for them.
I would request 3CX to allow the resellers to hide these menu items. If it can be done via code, we would gladly do it, if they told us what code to change. 3CX is going to lose customers and reseller like us are eventually going to go to other systems as the cost of answering calls over this confusion is not worth it.
