    The Developer's Guide to Phone Number Regulatory Compliance qMvMl-7km51ZMwhLfA9kzW7AuNTyFppuGJKF6KKCyEO9dww1zxhJx63sQtynlA-KcCmabxeF6CUXASv_llpD4QXQbcOQGAJ7XqhI_yzpb7HXAtbHgIXN1yGLCUkh7GdYQ7qocnay

    Regulatory compliance (RC) requirements for phone number users have increased worldwide. Depending on the phone number and its features, your or your company's status in the country, and your intentions for the number, different laws and regulations apply while building Voice, Fax, or SMS-based applications.

    While some of these regulations are new, many of these laws and rules have been in effect for some time. Countries are increasing enforcement for many reasons – including fraud, incidents of misuse and abuse and heightened national security concerns.

    All your Twilio phone numbers on Twilio’s platform need to comply with individual country requirements or they are at risk of being suspended until you submit proper RC information.

    Read on for what you need to know to bring an existing communications application into compliance or before starting a new application.

    Here's a video overview explaining what's happening:

    Is it Twilio Calling? Qs_oqEngzDxaWPALWSTVsd1EOtpKZSR9_nuRtnjpSjMdlCdYi6gI5a1sJ3QJv65hKveGaZz0tWALaXJXqmLPhO1BW-ogmiEK3K44pvBTbpyBgmwCLcMwdY8gXVlexgf-OeJDqY69

    Robocalls, automated phone calls usually delivering pre-recorded messages, are on pace to be roughly half of all US mobile phone calls in 2019. Americans are only answering about 52 percent of all calls to their mobile phones. Further, more than three out of every four calls go unanswered when the call comes from an unidentified or unfamiliar number.

    As a company providing a cloud communications platform, we are often asked about unwanted robocalling and whether we harbor robocallers and robotexters. Our CEO laid out Twilio’s feelings on robocallers in no uncertain terms:

    “We don’t. And, we don't want these robocallers on our platform.”

    Twilio’s communications platform

    Twilio is a platform for legitimate companies to send wanted communications to their customers – communications those customers have opted into. Whether that’s an alert about an upcoming doctor’s appointment, notice of a school closing, confirmation that a purchased ...

    Re-Introducing the Hackpack v4: Twilio's Open Source Hardware Badge signal2018_hp4_blogImg_r1_v1e.png

    Last week at SIGNAL 2018, we debuted v4 of our venerable hardware badge that we lovingly call the Hackpack.

    This year’s Hackpack was our most advanced yet. Sporting a joystick, 7 buttons, a touchscreen, a massive battery, and Linux on a Raspberry Pi Zero W, we hoped to craft the perfect badge for both our conference and your next handheld computing project.

    We also designed it with a special goal in mind: to release under an open hardware license. That’s why today we’re proud to announce the hardware collateral and assembly instructions are available under the Solderpad 2.0 license.

    Go to the hardware repository now.

    Building Twilio’s Hardware Badge

    We designed and built v4 of the Hackpack using version 5 of KiCad. And even if you never fire up KiCad, you can take the gerbers to your favorite PCB house and (with a fair bit ...

    Agricultural Monitoring with Twilio Programmable Wireless and Helium sEpjJ1aP3-jq_m-DMlOop9-UEgYjIyHYYkMPM6tMptg0WP4NABqcuqLTGbIYC6ucDkAvIdYs193UKyjb_NgcQLlm_DAz5mClzpvfJoMuAeNXYJVKcti4SqnHq82g06DCsNGiTZuw

    The Internet of Things certainly has potential – and for some applications it’s even currently performing. Smart farming is one of those fields (pun intended), where always-connected sensors can do better at crop monitoring than any human ever could. Watching moisture levels and other soil metrics is a perfect assignment for low-powered microcontrollers scattered throughout amber waves of grain.

    Building a Smart Farm with Arduino, Twilio and Helium

    Here in the Bay Area, lot sizes are measured in square footage not acreage – so excuse my diversion into hyperbole. At my house, I have a couple of 3’x6.5’ planter boxes where we grow herbs and root vegetables. Today, we’ll wire up a planter box and build an agricultural monitor using Twilio’s Programmable Wireless and SMS, along with a Helium Element Gateway, Helium Atom Prototyping Module and an Arduino Uno.

    On the accessories side, we’ll be using ...

    TwiML Bins: A Serverless and Codeless Way to Try Twilio twilio_banner_default.png

    In May, Twilio announced Twilio Functions, a serverless Node.js environment for spinning up functions without having to find hosting. Functions is an easy server replacement – but did you know we have other ways to rapidly build and iterate on your product serverless-ly? (Including a new visual communications tool, Twilio Studio, in developer preview).

    Today I’m thrilled to shine a light on TwiML Bins, an incredibly simple way to start building or prototyping with Twilio. TwiML Bins are all you need to enable very desirable – and previously quite expensive – communications features like Cloud-based Voicemail or SMS masking and forwarding with Twilio.

    Oh, and did I mention you won’t need to write a single line of code? Onward!

    Get Yourself a Twilio Number or Three

    The magic of TwiML Bins starts in the Twilio Console. Log into your Twilio account (or create a new one – try us free!), then ...

    Blink an ESP8266 LED in Real-Time using Twilio’s Sync for IoT esp8266_dev_board_on_wood

    If you’re anything like me, you’ve got an entire desk drawer full of hardware dev boards and sensors waiting patiently for a project. (Okay, fine, a garage storage rack.)

    That’s why I was so excited when we announced we’re bringing Twilio’s Sync to IoT devices. Sync is Twilio’s real-time state synchronization product, allowing you to persist, update, and check variable state from anywhere the internet is found. We added MQTT over TLS support to Sync, opening up Sync’s super-scalable architecture to many of those aforementioned drawer hardware devices.

    If you can’t tell, I’m over the moon at this development. Follow along with this blog post; we’re going to use an Espressif ESP8266 Dev Board, Sync for IoT, the Arduino IDE and billions of electrons to blink an LED from the command line.

    Sync-ing Our Capabilities

    Sync for IoT is currently ...

    5 Phones, 1950 Pixels: How MissionMode Hacked the SIGNAL 2017 Video Wall missionmode_vid_wall

    Code is Creative”.  You showed us how true that statement really is at this year’s SIGNAL San Francisco.

    Your creativity was made readily visible on the 40 foot video wall (and interactive art display) we hosted upstairs at the show.  We handed out Hackpacks, hackable hardware badges with a Particle Electron onboard, which had the ability to control that massive display via text messages.

    Poking, then Automating, then Drawing…

    One of the first groups to figure out how to draw on the video wall was our friends at MissionMode.

    By day, MissionMode builds incident management and notification solutions.  At SIGNAL, MissionMode proved they are also talented at reverse engineering. Their team of five SIGNAL attendees was the first to take down the full wall, drawing the MissionMode logo:

    I asked MissionMode if they would share some of their memories and “A-Ha!” moments from their awesome wall-hack and they kindly ...

    FAQ: Using Your HackPack v3 in a Post-SIGNAL World twilio_hackpack_logo

    This year at SIGNAL, every attendee got their own Particle Electron powered HackPack. The HackPacks controlled a big screen display upstairs at the show, allowing attendees to wow us in a live exhibit of the intersection of code and artistic creativity.

    We were so impressed with all the creativity on display at the conference.  Over 1,250 of you powered up your HackPack during the conference and accepted our challenge, nearly-instantly validating our conference charge to celebrate DOers.  You impressed us all with the awesome hacks you came up with and the amazing things you got our wall to do.  For that we thank you – you took the Big Board places we didn’t even imagine.

    By Saturday, June 3 we will be deactivating all SIM cards that have not yet added associated billing information to Particle accounts.  In plain English, this means that the onboard Particle Electron is yours ...
