You may change “Registration conflict mode” to “Overwrite” (default is “Reject”) then try to register your new C40.
This configuration is available under “VCS Configuration > Protocols > H.323”.
VCS will accept registration request from your C40, when will most probably remove from registration shortly.
You may find which device has duplicate H.323 ID or/and E.164 alias by checking registration history or/and registration status on VCS Web GUI (instead of taking diagnostic log and review it).
You may “Unregister” existing registered device from VCS from “Status > Registration > By device” but may original registered device send RRQ (Registration Request) before your new C40 which will end up same situation.
