    Elastic SIP Trunking: Call Transfer via SIP REFER Twilio Bug Logo

    If you’re running a multi-site Contact Center and you need to transfer a call from one agent to another agent in a different location, you can now send Twilio a SIP REFER message requesting that transfer.

    About call transfers

    A call transfer is just what it sounds like: It’s when you transfer a customer’s call from one call center agent to another. You might need to initiate a call transfer for several reasons, such as when a customer requesting to speak to the manager. Quick, easy call transfers are a necessary function in today’s business telecom environments.

    When an agent presses the “Transfer” button on a SIP-enabled IP phone, the phone issues a SIP REFER method requesting the call to be transferred to a third party using the contact information provided in the request.

    A very common type of call transfers is “blind” transfers. Blind transfers occur when a call …

    Introducing SIP Registration sipregistration

    We’re excited to introduce a new way to use the Twilio Voice API – via SIP Registration. Now you can connect your SIP-enabled devices or softphones directly to Twilio and use the Voice API to build nifty call-handling logic. For example, you can get phone numbers in nearly 50 countries for those phones. Then, decide if your phones ring sequentially or simultaneously. You can control call routing from your code, based on day of the week, time of day, or Caller ID.

    SIP Registration is available now and it’s free to register multiple devices per user. That’s enough to make even the most device-crazy person happy. The same Programmable Voice pricing for making and receiving calls will apply. To get started, check out the setup instructions below.

    But first, here are some early examples of how others are using SIP Registration.

    Pittsburgh Technical Institute Switches SIP Based Call Center To Twilio Pittsburgh_Technical_Institute

    Pittsburgh Technical Institute (PTI) has been helping students launch a new career path with a post-secondary degree for over 70 years. PTI prides themselves on being attuned to the job market, keeping its curriculum current to ensure their students are successful after graduation.

    As the school evolved, their communications stack stayed the same, costing PTI time and money. Using Twilio, PTI overhauled their SIP-based call center and built out a live chat feature integrated with their CRM with ease. And it all started with a school art show.

    Planting A Seed

    In 2012, William Showers, the Director of Information Technology at PTI, wanted to build an SMS voting service for an art-show PTI put on. He did some googling and found his way to the Twilio SMS API docs. Shortly after, he had an app up and running. A seed was planted.

    How to Make, Track and Automate Calls with Twilio in Agile CRM agilecrm-logo-icon-png

    Agile CRM built Twilio SIP functionality into their CRM to allow sales agents to make, record, and receive calls from the browser. The integration is making customers happier, and sales agents more effective.

    Great CRMs should make life easier for the customer as well as the caller. The key to a great experience for both parties is context. The sales reps making calls should have the customer’s usage history, past communications, and support tickets right in front of them when they make a call. The customer shouldn’t have to repeat basic information back to the rep.

    In this blog post, Agile CRM will teach you how to quickly set up the integration, make and receive calls, record calls, and run call campaigns.

    Setting Up The SIP Integration

    Communications integrations in Agile CRM take the form of customizable widgets on contact pages in the CRM. To activate the Twilio widget, you’ll …
