Elastic SIP Trunking: Call Transfer via SIP REFER
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 ...

Elastic SIP Trunking now supports Caller ID Name (CNAM) Lookup
- Make informed decisions on which calls to answer by surfacing Caller ID data with CNAM Lookup.
- Caller ID Data added to Twilio Lookup to allow you query the CNAM database on demand via REST API.
- Retrieve CNAM data on an in-progress call and use it to query your system of record to surface relevant caller information.

That’s why we’re excited to announce CNAM Lookup for Elastic SIP Trunking. Now every time the phone rings, you know who’s on the other end of the line and whether you should answer or let the call go to voicemail.
CNAM is an acronym which stands for Caller ID Name. With CNAM Lookup, the calling party’s name is automatically displayed alongside the phone number, to help users easily identify a caller.

SIP Trunking Termination Calling is Now More Flexible with Master CPS
- Enhancement to Calls Per Second (CPS) feature for SIP Trunking termination.
- Save money and gain more control over capacity planning.
- Available in beta.
Today, we’re excited to announce a huge enhancement to the Calls Per Second (CPS) feature for SIP Trunking termination. Master CPS is a feature that will save you money if using our traditional CPS feature today while allowing you to have more control over your capacity planning. It’s a win-win!
What is CPS?
Before getting into all the exciting details of this enhancement, let’s take a step back for a moment to understand what CPS is and how it relates to concurrency, a term more familiar amongst traditional SIP providers like AT&T and Verizon.
Concurrency refers to how many simultaneous calls can occur at same time. These traditional providers require you to plan for your highest peak traffic days, determine the highest number of ...
Reduce Your Bill With Origin-Based Pricing
Have you built a Contact Center, Click-to-Dial, or Voice Notification solution using Outbound Voice or Elastic SIP Trunking with calls localized in Europe? Yes? Then read on to find out how you can save money.
This month Twilio expanded its coverage of Origin-Based Pricing by adding Belgium and Netherlands now for a total of 19 European countries. Prices to these 19 European countries have dropped an average of 72% compared to the rest of world and are now $0.13 per minute less expensive compared to other providers. This means calls that stay local within Europe can realize significant price reductions—all you do is set the Caller ID with a qualifying local EU/EEA number you own.
This opportunity for price reduction can be realized with both:
- Programmable Voice – Outbound
- Elastic SIP Trunking – Terminating
What is Origin-Based pricing?
Origin-Based pricing means that calls to the same destination have ...
Elastic SIP Trunking: Region selection for origination traffic
If you’re using Twilio Elastic SIP Trunking to connect your IP-based communications infrastructure to the PSTN, then you’ll be happy to hear that starting today, you can specify the geographic region that Twilio will use to send the originating SIP traffic.
By default, Twilio uses the region where the incoming PSTN call comes in from. Starting today, to specify the region you want Twilio to use to send the originating SIP request towards your communications infrastructure, simply include the optional region parameter in your origination SIP URI. This can lead to improved voice quality as traffic will not automatically traverse to the region of the incoming PSTN and, moving forward, calls will be directed over the Twilio Super Network—to the specified region—instead of the public internet.
For example, by including region=ie1 in your origination SIP URI, Twilio will send the SIP request from the Europe ...
SIP Interface adds support for international regions

This means that when you send SIP to Twilio, or receive SIP from Twilio, you can specify the region that’s closest to the location of your communications infrastructure to ensure the best quality of service.

<?xml version="1.0" encoding="UTF-8"?> <Response> <Dial> <Sip>sip:firstname.lastname@example.org;region=ie1< ...
