App provides Voice over IP services 应用审核被拒

Your app declares support for VoIP in the UIBackgroundModes key in your Info.plist, but does not include any Voice over IP services.
Next Steps

Please revise your app to either add VoIP features or remove the "voip" setting from the UIBackgroundModes key.

We recognize that VoIP can provide "keep alive" functionality that is useful for many app features. However, using VoIP in this manner is not the intended purpose of VoIP.
