Ignore missed calls on busy

[Yealink_Peter]

Hi,

If you do not "touch" the call at all, it will add the incoming call to the missed calls log, can't be blocked, as well as for call waiting. But if you actually deny the incoming call, it won't display in the missed calls log, we have double confirmed from our side testing.
There is an option which allow you to disable the missed call log at the phone wui->account->basic->missed call log, if you set it to disabled, all kinds of missed calls will not be added in the log, but I think it might not what you want.

Thank you!
Regards,
Peter
