At the core of the SDK is the Webex object, serving as the gateway to all SDK functionalities. The Call object represents an active call and provides methods to manage various aspects of the call lifecycle, such as answering, hanging up, muting, and unmuting. You obtain a Call object either as a result of a successful outgoing call through the dial method or as an incoming call event.

anchorMake an Outgoing Call

To place an outgoing call, use the dialPhoneNumber method:

webex.phone.dialPhoneNumber("+1800123456", option: MediaOption.audioOnly()) { result in
    switch result {
    case .success(let call):
        call.onConnected = {
            // ...
        }
        call.onDisconnected = { reason in
            // ...
        }
    case .failure(let error):
        //call failure
    } 
}

anchorReceive and Answer a Call

Incoming calls are handled by setting a listener on the onIncoming event of the phone object:

webex.phone.onIncoming = { call in
    call.answer(option: MediaOption.audioVideo(local: ..., remote: ...)) { error in
    if let error = error {
        // failure
    }
    else {
        // success
    }
}

anchorDetermine a User's Calling Type

To determine if the signed-in user is entitled to use Webex Calling, check their calling type:

if(webex.phone.getCallingType() == Phone.CallingType.WebexCalling){
    // Indicates Webex Calling is supported for signed in user
}

anchorCheck Feature Entitlements for the Logged-in User

The user's license dictates their access to messaging, meeting, and calling features. The webex.people.getProductCapability() method enables you to verify the user's product capabilities:

let capability: ProductCapability = webex.people.getProductCapability()
let hasCalling = capability.isCallingSupported
let hasMeeting = capability.isMeetingSupported
let hasMessaging = capability.isMessagingSupported
