Disable call waiting feature for calls made to a user extension
Currently calls that are made directly to an extension still rings the 1st forwarding phone of the extension although the user is already engaged in a call. We need to have a feature to disable it, if the user extension is already engaged in a call, the next call should not ring the phone and it should divert to the next available forwarding phone.

We have a request from a department in our organisation that if any of their users are engaged in a call they do not want new direct calls to the user are engaged in that call popping up on their RingCentral App for that 10 seconds but would like the new the call to them routed immediately to their Call Queue so that someone else in the Call Queue can deal with the call
