The Twilio Programmable Voice SDKs allow you to add voice-over-IP (VoIP) calling to your native iOS applications.
To make sure your app is ready for iOS 14, visit this page.
Apps using SDK versions 2.0.x, 3.x, and 4.x may fail to register for incoming calls when running on iOS 13. We recommend that you upgrade to SDK 5.0 or above. Refer to this advisory and this GitHub issue for more information. Check out our migration guides when planning your move to our latest SDK.
The Twilio Programmable Voice SDKs use Semantic Versioning. Twilio supports version N-1 for 12 months after the first GA release of version N. We recommend you upgrade to the latest version as soon as possible to avoid any breaking changes. Version 6.x is the latest iOS version.
Support for 4.x ceased on September 19, 2020. Please upgrade to the latest version
Support for 3.x ceased on June 28, 2020. Please upgrade to the latest version
Support for 2.x ceased on January 1, 2020. Please upgrade to the latest version
End-of-Life for 1.x will occur on March 23, 2021. A two-hour maintenance period is planned for 1.x at 9am Pacific Time on January 26, 2021. Please upgrade to the latest version. See this EoL notice for further details.

The SDK now supports sending and receiving in-call user-defined messages. Use the [TVOCall sendMessage:]
method to send
messages. Endpoints subscribed to the events of the call will be receiving the messages. The [TVOCallMessageDelegate call:didReceiveMessage:]
callback will be raised to the application when a message is received by the client.
Please visit this page for more details about this feature. Additionally, please see the following for more information on how to send and receive messages on the server.
NOTE: This feature should not be used with PII.
The TVOCallMessage
class and the TVOCallMessageBuilder
class are introduced to represent the call messages.
Example of sending a call message:
1let call = TwilioVoiceSDK.connect(options: connectOptions, delegate: self)23// wait for call to be connected45let message = "{ \"foo\": \"bar\", \"marco\": \"polo\" }"6let callMessage = CallMessage(content: message)78// voiceEventSid can be used for tracking the message9let voiceEventSid = call.sendMessage(callMessage)1011extension ViewController: CallMessageDelegate {12func callDidSendMessage(call: Call, voiceEventSid: String) {13NSLog("Call message sent.

API change
The Voice SDK has been updated for better Swift interoperability.
TVO
prefix has been removed from all Twilio Voice typesThis release has improved API for CallKit integration. In order to use CallKit with SDK, you must set ConnectOptions.uuid
or AcceptOptions.uuid
while making or answering a Call. When ConnectOptions.uuid
or AcceptOptions.uuid
is set, it is your responsibility to enable and disable the audio device. You should enable the audio device in [CXProviderDelegate provider:didActivateAudioSession:]
, and disable the audio device in [CXProviderDelegate provider:didDeactivateAudioSession:]
.
1func provider(_ provider: CXProvider, didActivate audioSession: AVAudioSession) {2audioDevice.isEnabled = true3}45func provider(_ provider: CXProvider, didDeactivate audioSession: AVAudioSession) {6audioDevice.isEnabled = false7}89func providerDidReset(_ provider: CXProvider) {10audioDevice.isEnabled = false11}
If you are not using CallKit in your app, you must not set ConnectOptions.uuid
or AcceptOptions.uuid
while making or answering a call. The Voice SDK will enable the audio device for you when the uuid
is nil
.
uuid
property of TVOCall
is now optional.[TVOCallDelegate callDidConnect:]
such that it is raised when both ICE connection state is connected and DTLS negotiation has completed. Previously [TVOCallDelegate callDidConnect:]
was raised when the DTLS negotiation had completed.[TVOCallDelegate callDidConnect:]
is raised when both the ICE connection state is connected and DTLS negotiation has completed. There is no change in behavior however the SDK can detect DTLS failures and raise kTVOMediaDtlsTransportFailedErrorCode
if they occur.Error Codes | ErrorCode | Error Message |

A TVOCallerInfo
class is introduced to represent information about the caller. Currently, this information is limited to SHAKEN/STIR
status of incoming PSTN Calls, but may later be expanded to include CNAM
, and other endpoint types. The verified
property represents whether or not the caller's phone number has been verified by Twilio using SHAKEN/STIR
validation. The value of this attribute is true
if the caller has been validated at 'A'
level, false
if the caller has been verified at any lower level or has failed validation. If SHAKEN/STIR
information is unavailable for the caller or stir status value is null
, the property will be nil
. For details on how Twilio uses SHAKEN/STIR
to make trusted calls and protect against unlawful spoofing, please visit /docs/voice/trusted-calling-using-shakenstir.
New property callerInfo
in TVOCallInvite
returns the TVOCallerInfo
object to represent the information about the caller.

Network degradation warnings were previously only logged to Insights. With this release, a new TVOCallDelegate
method call:didReceiveQualityWarnings:previousWarnings:
is also invoked when the SDK detects those degradations. Use these to relay network condition to the user to provide a better user experience. See the delegate method and callQualityWarnings for more information.

. Use [TVOCall getStatsWithBlock:]
during a Call to retrieve the score. Since the MOS is calculated from network performance measurements, it can be used to indicate the current network condition to the user to provide better usability.
By default ICE gathering is done on all interfaces except some VPN type interfaces. This makes it impossible to connect to Twilio in networks that require the use of VPN. In this release, the new Boolean property enableIceGatheringOnAnyAddressPorts
in TVOCallOptionsBuilder
allows the gathering of ICE candidates from all available interfaces. This should be used in those networks where the default does not work. See enableIceGatheringOnAnyAddressPorts for more information.

This release adds support for the new PushKit push notification policy that iOS 13 and Xcode 11 introduced. To upgrade your application please follow the migration guide.
Insights
To provide observability for incoming call cancellations the following Insights events have been added:
Event Group | Event Name | Level | Description |
---|---|---|---|
connection | listen | info | Reported when an attempt to listen for cancellations is made |
connection | listening | info | Reported when an attempt to listen for cancellations has succeeded |
connection | cancel | info | Reported when a cancellation has been reported |
connection | listening-error | error | Reported when an attempt to listen for a cancellation has failed |
registration | unsupported-cancel-message-error | error | Reported when a "cancel" push notification is processed by the SDK. This version of the SDK does not support "cancel" push notifications |
API Changes
Starting with 5.0.0, when [TwilioVoice registerWithAccessToken:deviceToken:completion:]
is called, the Voice SDK will only register for "call" push notifications and cancelled call invites will be determined internally by the SDK. [TwilioVoice handleNotification:delegate:delegateQueue:]
no longer processes "cancel" push notification payloads and will returnfalse
if provided with a cancel notification.
A valid call push notification, when passed to [TwilioVoice handleNotification:delegate:delegateQueue:]
, will still result in a TVOCallInvite
being raised [TVONotificationDelegate callInviteReceived:]
. A TVOCancelledCallInvite
will be raised asynchronously via [TVONotificationDelegate cancelledCallInviteReceived:error:]
if any of the following events occur:
TVOCallInvite
to be notified of a cancellation via [TVONotificationDelegate cancelledCallInviteReceived:error:]
.
A TVOCancelledCallInvite
will not be raised if the invite is accepted or rejected.[TwilioVoice handleNotification:delegate:]
is now [TwilioVoice handleNotification:delegate:delegateQueue:]
delegateQueue
: the dispatch queue where the [TVONotificationDelegate cancelledCallInviteReceived:error:]
callback is received. If nil
is passed, the dispatch main queue will be used.[TVONotificationDelegate callInviteReceived:]
callback synchronously.false
.[TVONotificationDelegate cancelledCallInviteReceived:]
is now [TVONotificationDelegate cancelledCallInviteReceived:error:]
error
indicates that the call was canceled as a result of an error. The error.code
will be set to TVOErrorCallCancelledError
if a caller cancels the call before the called party could answer the call.The property enableInsights
has been renamed to insights
and moved from TVOCallOptions.h
to TwilioVoice.h
.
The property region
has moved from TVOCallOptions.h
to TwilioVoice.h
. If you are specifying a region via the TwilioVoice.h
region property you must now do so before [TwilioVoice connectWithAccessToken:delegate:]
or [TwilioVoice handleNotification:delegate:delegateQueue:]
is called.
Class method [TVOCallInvite isValid:]
is added to TVOCallInvite
for apps to validate whether the notification payload is a valid call notification sent by Twilio. A valid notification payload will result in a TVOCallInvite
being returned via the [TVONotificationDelegate callInviteReceived:]
callback when passed to [TwilioVoice handleNotification:delegate:delegateQueue:]
.

Enhancements
The Differentiated Services Code Point (DSCP) Tagging API allows you to mark the audio packets with Expedited Forwarding (EF) for the purposes of improved packet routing. When enabled, supporting networks will prioritize audio packet delivery for improved audio quality.
Use enableDscp
to enable or disable DSCP tagging. Note, enableDscp
is enabled by default.
For example:
1// Configure DSCP with `TVOConnectOptions`2let connectOptions = TVOConnectOptions(accessToken: accessToken) { (builder) in3builder.enableDscp = true4}56let call = TwilioVoice.connect(with: connectOptions, delegate: callDelegate)
1// Configure DSCP with `TVOAcceptOptions`2let acceptOptions = TVOAcceptOptions(accessToken: accessToken) { (builder) in3builder.enableDscp = true4}56let call = callInvite.accept(with: acceptOptions, delegate: callDelegate)

New Features
Max Average Bandwidth API
By default, the Opus codec is set up with a transmission rate of around 32 kbps (40-50kbps on the wire). With this release, you are able to set a custom max average bitrate to better control how much bandwidth your VoIP application should use. See RFC-7587 section 7.1 for information about Max Average Bitrate.
The main purpose of this API is to set a lower max average bitrate to minimise bandwidth usage. This is particularly useful in deployments where bandwidth is at a premium. Where bandwidth is not of concern, you do not need to use this API.
Max Average Bitrate can be set to as low as 6,000bps and as high as 51,000 bps. Values outside this range are ignored and the default Opus operation mode is used. See API Docs for more information.
As would be expected, lowering the max average bitrate impacts audio quality. We don't recommend setting max average bitrate to a value below 8,000 bps. On the other hand, setting values over 32,000 bps will have negligible audio quality improvements.
For example, to set a new max average bitrate to 16,000 bps:
1let connectOptions = TVOConnectOptions(accessToken: accessToken) { (builder) in2builder.params = params3builder.preferredAudioCodecs = [TVOOpusCodec(maxAverageBitrate: 16000)]4}56let call = TwilioVoice.connect(with: connectOptions, delegate: callDelegate)

New Features
Reconnecting State API
This release introduces the new Reconnecting State API
. This API adds a new state TVOCallStateReconnecting
to TVOCallState
and two new optional TVOCallDelegate
methods, call:isReconnectingWithError:
and callDidReconnect:
.
Call reconnection capability has been available since SDK 3.0. For example, if a call is established over a Wi-Fi network and the Wi-Fi network becomes unavailable, the SDK will automatically switch the call over to the next available network.
This release adds the reconnection related callbacks. call:isReconnectingWithError:
is invoked to indicate a call is being reconnected due to a network disruption or network switch over and callDidReconnect:
is called once the call has been re-connected. You can use this information to provide intuitive feedback to your App user when a reconnection is taking place.
Enhancements
Passing a malformed callee to either [TwilioVoice connectWithAccessToken:] or [TwilioVoice connectWithOptions:delegate:] will now result in TVOErrorAddressIncompleteError

Enhancements
Improved error codes
We now surface more details about errors encountered during [TwilioVoice registerWithAccessToken:deviceToken:completion:], [TwilioVoice unregisterWithAccessToken:deviceToken:completion:], [TwilioVoice connectWithOptions:delegate:], and [TVOCallInvite acceptWithOptions:delegate:]. Previously, these functions reported these errors with the generic error TVOErrorRegistrationError
or TVOErrorConnectionError
.
With the new error codes, you can make more informed decisions with how to remedy the problem. For example, TVOErrorBadRequestError and TVOErrorTooManyRequestsError indicate potential programming issues, while TVOErrorTokenAuthenticationRejected indicate an issue with your Access Token.
Please note, you may need to change your code if you have added special handling for TVOErrorRegistrationError
or TVOErrorConnectionError
.
