When there is an ongoing call, if the user gets another one, we don't want to support multi-call and directly send the new call to the voicemail. For this operation what should be CXCallEndedReason?
My understanding is that remoteEnded is used when the call connected and then ended. unanswered might be the choice for me but would it cause any issue if i directly reject a call with this status (the difference between the incoming call and reject time would be too short)? There is also declinedElsewhere , which might be suitable
