Twilio Programmable Call Recordings now allows PCI compliant call recordings within the Twilio Programmable Voice environment. By providing a public key to encrypt recordings and enabling PCI Mode in Console, call recordings can be captured in a PCI compliant manner.

Traditionally, call recordings are used to analyze agent and customer interactions. However, they require special handling when capturing credit card information. To continue to record your voice calls and maintain PCI compliance within Twilio, you must have PCI Mode, Voice Recording Encryption and PCI compliance for Voice Recording enabled using Voice Settings Console page.

Once these settings are enabled on a project, Call Recordings will only be stored by Twilio for 72 hours and must be retrieved within this period. Once deleted, these recordings will no longer be recoverable by either Twilio Console or API request.

Twilio Bring Your Own Carrier (BYOC) Trunking for Programmable Voice is now Generally Available. BYOC Trunking is a distinct new offering that allows you to use your existing PSTN Voice Carrier partner(s), keep your phone numbers with that Carrier, and add Twilio Programmable Voice capabilities at your own pace.

• Add programmability to your existing Phone Numbers by redirecting incoming calls delivered by your PSTN Carrier to Twilio (Termination).
  
• Send outgoing calls directly to your PSTN Carrier, including redundancy and load-balancing across multiple SIP destinations, and use Twilio’s Super Network as a fallback (Origination).
• No porting is necessary.

You can now send and receive contact cards, also known as VCards or VCF (Virtual Contact Files), via WhatsApp! Contact cards let people easily share and add new contacts to their phone book.

When a user receives and taps on a vCard in WhatsApp, the app will render a preview and allow them to easily call or add the contact to their phone book.

In WhatsApp, VCards are useful for businesses that send links to users, but have not yet been able to become an Official Business Account. For these businesses, links will only be clickable when the business has been added as a contact.

To send a vCard, simply send it as a file as you would with any other media.

Previously for the Twilio console, we supported two factor authentication via SMS, Voice and the Authy app, to secure customer accounts. With this update, we added support for other TOTP-standard apps, so customers can bring their own authenticator apps to protect their Twilio account with 2FA. This expands the set of options available to customers to secure their login to the Twilio console. To use a TOTP-compliant app, you can enable two factor authentication (2FA) via User Settings, select ‘Another authenticator app’ for 2FA method and follow the steps for setup. For full details, read this help article.

The AudioDevice API is an advanced API that can be used to create innovative and sophisticated in-app audio capabilities. For example, enable pre-recorded messages to be played in-call, or apply noise reduction algorithms before playing out the received audio.

An AudioDevice is a logical device that is used to capture and render audio. The captured audio is sent to the remote party, and the received audio is rendered locally. By default, the SDK uses DefaultAudioDevice which uses the mic for capturing and the local speaker/earpiece/headset for rendering. The AudioDevice API allows for the creation of custom audio capturers and renderers. See this example and API docs to learn more about custom audio devices.
