    SIP レジストレーションにおけるエッジロケーションへの対応 SIP Registration Locality JP

    この記事は英語版ブログ記事の抄訳です。

    SIPレジストレーションを行うことで、SIP対応デバイスやソフトフォンをTwilioに直接接続することができます。またProgrammable Voice APIを使用して、複雑なハードウェアやネットワークへの物理接続を必要とせずに、強力なコール処理ロジックを構築することができます。おなじみのTwilioアプリケーションを使って、PSTNやWebRTC/モバイルクライアントと同じようにSIPエンドポイントに接続することができるのです。しかしこれまでは、レジストレーション済みSIPデバイスはグローバルにコールを発着信することができるものの、SIPレジストレーション先は、米国バージニア州アッシュバーン(米国東部)にある当社データセンターに限定されていました。

    そのような中、2020年6月に、アプリケーションのパフォーマンス向上視点からのエッジロケーション対応機能を新たに発表しました。またこの新機能を通してお届けした基盤を活用し、更にエンドユーザーのコミュニケーション体験向上に貢献する機能をお届けしたいと考えていました。

    そして今回、SIPレジストレーションが、世界中のパブリックおよびプライベートのエッジロケーションに対応できるようになったことをお知らせ致します。これにより、お客様の所在に最も近いエッジロケーションにSIPデバイスをレジストレーションし、デバイス接続のパフォーマンスと耐障害性を向上させることができます。

    エッジロケーション経由で登録すると、アプリケーションのパフォーマンスが向上し、以下のようなメリットがもたら …

    Announcing Support for Regional Twilio SIP Registration Regional SIP Registration

     

    SIP Registration allows you to connect your SIP-enabled devices or softphones directly to Twilio, and use the Programmable Voice API to build powerful call-handling logic without standing up complex hardware or physical connections to your network. You can use the Twilio applications you know and love to connect to SIP endpoints the same way you do to the PSTN or WebRTC/Mobile clients. Until now, however, while your registered SIP devices could make and receive calls globally, your endpoints could only register to Twilio via our US-East data center in Ashburn, VA, USA.

    Earlier this year, we announced new Twilio Edge Locations to improve application performance. With this launch, we are building on top of what we delivered to improve the end-user experience.

    Today, we are happy to announce that Twilio SIP Registration is now accessible via our public and private Edge Locations worldwide. Now you can register your SIP device …

    Two More Reasons to Use Twilio Programmable Voice with Your SIP Network Programmable Voice Multidial Blind transfer

    As we continue to grow and develop our Programmable Voice portfolio, we are excited to announce the addition of new capabilities to enhance the overall user experience. These features will enable you to use the applications you have developed for PSTN and Client access interchangeably with your SIP endpoints too.

    Support for Blind Transfer with addition of inbound SIP REFER to Twilio

    The SIP REFER method enables moving an active SIP session from one SIP endpoint to another. In other words, REFER is used to implement call transfers on your SIP-connected calls. Until now, Twilio has only supported sending outbound SIP REFER messages to your SIP network, using the TwiML <Refer> verb.

    Today, we are announcing support of inbound SIP REFER messages, meaning you now can send SIP REFER messages from your SIP network to Twilio in order to initiate call handling in your application. Effectively, this means that Twilio …

    A Crash Course in SIP Trunking SIP Trunking 2.png

    Twenty years ago, when SIP trunking and VoIP were introduced on the world stage, we hadn’t yet dreamed of all of the ways that the internet would revolutionize how we connect with each other. Now, using the platform of our preference, unified communication online has become a part of our everyday lives.

    Phone calls still hold strong as a tried-and-true method of communication in a world that loves text, email, and messaging. Increasingly, businesses are leaning on VoIP and SIP trunking to meet the demand for affordable (and scalable) person-to-person communication.

    As we increase our reliance on online communication, SIP trunking frequently becomes the subject of conversation regarding digital transitions. Although SIP trunking is a hot topic, it can be easy to gloss over the basics of how it works and why it can be transformative for your business. Never fear, we’ve got you covered! Here’s everything you need …

    How to Secure Your SIP Trunks with Twilio Secure SIP Trunk

    The world has changed, thanks to the Internet. We are able to collaborate and build quickly and efficiently. But – this phenomenon has also increased the number of security risks and attempts by hackers to extract valuable information.

    Comparing Cloud vs. Telco SIP Trunks: Which is Better? telco vs cloudv3.png

    Selecting a SIP trunking service provider may seem like a straight-forward decision to many IT managers. After a brief evaluation, they might conclude the services are commodities with little differentiation, especially given the fact SIP trunking has been available for more than a decade and adoption is widespread in most industrialized countries. But reality is quite different, there are several factors that differentiate them.

    The SIP trunking services market is vibrant and dynamic with many providers competing for business with innovative offerings. Two broad provider categories have been established: traditional wireline telecommunications providers and communications platforms as a service. The traditional companies are often referred to as telcos, while the communication platform companies are referred to as CPaaS or cloud companies. These categories are differentiated by their investments in wireline transmission facilities.

    Depending upon an organization’s needs, a telecommunications provider may be a better fit than a CPaaS, or vice-versa. …

    Working around PSTN congestion with Twilio Client Working around PSTN congestion with Twilio Client

    In these unprecedented times of social distancing and a virus pandemic, we are seeing a huge increase in the number of voice calls being made. Our Super Network team is working around the clock to ensure that calls make it through. However, in some areas, we are seeing that lines from carriers are so congested that the calls are never reaching Twilio. Here in this tutorial, we will outline some options to bypass the congestion on the PSTN by using Twilio Client.

    Twilio Client is a WebRTC based voice client that works in browsers and mobile devices using a data connection. Once a client call is connected to Twilio it can be routed directly to your existing infrastructure via SIP or uncongested PSTN paths allowing calls to continue to flow.

    The Idea

    Currently, your customers and staff may be struggling to connect to your contact centers or business-critical services …
