1. You need call ‘-(BOOL)isSupportPhone’ first to determine if your account supports the call out feature.
2. If supported, call ‘-(NSArray\*)getSupportCountryInfo’ to get an array which contains ZoomSDKPhoneSupportCountryInfoList objects of all countries supporting to call out.
3. Call ‘-(ZoomSDKError)inviteCalloutUser:(NSString\*)userName PhoneNumber:(NSString\*)number CountryCode:(NSString\*)countryCode’ with param ‘countryCode’ is contains in the array get from ‘-(NSArray\*)getSupportCountryInfo’.
