Telephone Call-Out

Im looking to add in a Telephone Call-Out similar to Zoom Rooms iPad app into my MacOS application. Is this in the road map to add into the sdk, and if so how long till release? Also is there any plans to release your road map so we can see what is/isn’t coming?



Hi Daniel,

Call-out is already available on Mac SDK, please get the latest version

let me know if you need anything else.




Hello Wei,

Thanks for the reply.

I have made another account and purchased Call-Out services and have been trying to call my cellphone via the method “calloutH323Device”

Steps I take:

  1. Join my meeting room via sdk

  2. Once I am in a meeting I have a button 

  • (IBAction)callTest:(id)sender {

    H323DeviceInfo* info = [[H323DeviceInfo alloc] init]; = @“dan”;

    info.ip = @"";

    info.e164num = @"+16045554444"; <-- fake number for this post

    info.type= H323DeviceType_Unknown;

    ZoomSDKMeetingService* meetingService = [[ZoomSDK sharedSDK] getMeetingService];

    ZoomSDKError result = [[meetingService getH323Helper] calloutH323Device:info];

    if (result != ZoomSDKError_Success) {

        NSLog(@“Call out device failed!”);



and I get the result result “ZoomSDKError ZoomSDKError_InvalidPrameter”

I have also tried calling my cellphone from your ZoomSDKSample and get the same issue, and I have been trying all the combinations of device types.

Any help to get this working would be appreciated.


Hi Daniel,

could you change info.type= H323DeviceType_Unknown to : “info.type=H323DeviceType_H323” ?



I have tried all of the types and I can’t call out





all give the result “ZoomSDKError_InvalidPrameter”

Hi Daniel,

you put a number but not an IP address for H323 device, I think this is wrong. 

if you want to call your cell phone, you can also use this API:

-(ZoomSDKError)callMe:(NSString*)number CountryCode:(NSString*)countryCode; in ZoomSDKPhoneHelper
