    Twilio Elastic SIP Trunking Delivers Global PSTN Access for Genesys Cloud twilio-genesys.png

    Contact center managers and architects planning a migration to the Genesys Cloud service will encounter an important decision that they may not have given a lot of thought to. It’s about how best to connect their customers to Genesys Cloud. There are multiple PSTN connectivity options available to Genesys customers and each presents trade-offs that affect business agility, cost, customer experience and other factors.

    Genesys offers a “bring your own carrier” (BYOC) approach, which gives organizations the flexibility to select their voice services for Genesys Cloud. This gives Genesys customers access to a range of PSTN connectivity services to fit their business needs. You can leverage global SIP trunking services from third-party providers, including Twilio, and realize geographic coverage, pricing, flexibility and other advantages.

    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 …

    Bring Live Transcription to Your Existing PABX live-transcribe-pabx.png

    I often find myself in conversations with customers who are unsure about where to start with Twilio and their PABX. They have a great idea to improve customer experience, but they usually have an existing PABX that doesn't allow them to innovate at the speed they need to differentiate.

    Most start to plan how they can retire their existing estate. Quickly, they realize that it is going to be an uphill battle. Many then resign themselves to the "that's just how it is" mentality, log a feature request with their existing vendor, and then hope that enough other customers want the same feature that the vendor builds it.

    But what if there was another way? With Twilio Programmable Voice, you can keep your existing PABX and introduce cutting edge features and technology into a roadmap that you own.

    The Problem: Lack of Real-Time Transcription

    I faced this situation with …

    Transfer calls with context using SIP Refer from Twilio and SIP UUI Header Transfer calls with context using SIP Refer from Twilio and SIP UUI Header

    Today we are thrilled to announce that SIP Refer from Twilio is now generally available for call centers looking to transfer calls from Twilio to their SIP infrastructure. This enables call centers to save money on their calls by removing Twilio from the call path. When used in conjunction with SIP UUI Headers, a feature released this summer, context from Twilio can be passed along with the SIP Refer.

    Call Centers can use SIP Refer and SIP UUI Headers to transfer calls from Twilio to their internal SIP infrastructure, while maintaining call context, in order to transfer the call back to their IP infrastructure and handle sensitive information internally.

    Transfer the call back to your IP infrastructure

    When a customer calls into a contact center through Twilio to speak with Agent 1, Agent 1 can now transfer the call and pass relevant information to Agent 2 through their internal SIP …

    A Step-by-Step Guide to Set Up Twilio Elastic SIP Trunking Copy of Generic Blog Header 2-3.png

    In my last blog post, Registering a SIP Phone Directly to Twilio (and so much more...), we set up a Twilio Programmable Voice SIP Domain and registered our SIP softphones directly to Twilio. This let us place and receive calls to the Public Switched Telephone Network (PSTN) but more importantly, set up the foundation for building creative applications which intelligently route calls using dynamically returned Twilio Markup Language (TwiML).

    In this post we’ll provide a step-by-step approach to connect your SIP element – IP-PBX, SIP-PRI IAD, SBC, etc. – to Twilio’s Elastic SIP Trunking product. By the end of this post, you’ll have your existing communications infrastructure connected through Twilio and ready to layer on a number of Twilio’s other features.

    At its most basic level, Twilio Elastic SIP trunking provides dynamic trunking capacity to place and receive pay-as-you-go phone calls through Twilio. Twilio’s network …
