Current active phone call is terminated on receiving Voip Push Notification on iOS 13

Question

Cellular call running and incoming VoIP push failing cellular call on iOS 13, even if incoming call showing on below method.

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type

Showing Incoming call-kit screen when VoIP push received.

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type {

    [self displayIncomingCall:callbackUUIDToken handle:_payLoad.handle hasVideo:([_payLoad.pushType caseInsensitiveCompare:PUSH_TYPE_VIDEO_CALL] == NSOrderedSame)
        withCompletion:^(NSError *error) {

    }];
}

Disconnecting cellular call, while Face-time and Whatsapp call works as expected.
