Twilio Interconnect

Twilio offers numerous cloud based communication products and APIs that can be consumed by developers to build their applications and tools to further communicate with their own customers and users to enhance their user experience.

In order to accomplish the above however, a network connection to Twilio is required, which can be over the open Internet or via a secure, private connection.

Open Internet although convenient, by definition has the inherent "best effort" service delivery and lack of security which makes it NOT the right option for many customers and organizations that have QoS and bandwidth requirements as well as stringent security requirements.

Twilio Interconnect provides private connection(s) between your network and Twilio offering the best performance, data throughput and lowest latency. In addition, since your data never touches the public internet, it provides the best security and can guarantee quality from end-to-end.

With Twilio Interconnect, you can establish physical or virtual connections to Twilio in order to have a private and secure communication traffic, improve network availability and quality of service, guaranteed throughput, and ensure a more consistent network experience compared to connections via the open Internet which inherently are "best effort" delivery with no quality or service guarantee, not to mention that they are open to malicious acts and can easily be intercepted and subject to eavesdropping.

Choosing the Product that is right for you

There are several reasons why Interconnect is a preferred method of connecting to Twilio. High Availability, Guaranteed data throughput, quality of service and enterprise-grade security are among a few . If you need highly consistent connectivity between your communication infrastructure and Twilio, then Twilio Interconnect is the right choice. Also, if you have policies (internal or external) [ex:HIPAA, PCI, GDPR] that preclude you from sending traffic across the open Internet, Twilio Interconnect will keep your communication data within secure, private networks.

Twilio Interconnect has several flavors to accomodate various use cases:

Cross Connect allows you to set up a dedicated, physical fiber interconnection with Twilio.

Third Party Exchange is another way of having a private connection through a third party provider that Twilio has an exchange agreement with.

Bring Your Own MPLS is designed for you if you already have an MPLS network and would like to connect with Twilio.

VPN is the best option if you want to quickly try something out and play with some ideas OR if you have no presence in any of either our or our partner's data centers and wish to have a secure connection with us.

Twilio Exchange Locations

Each Twilio region has dedicated equipment to offer secure interconnect services as listed in the table below. Once you choose your Exchange location and the desired bandwidth, Twilio will provision the required bandwidth for your connections at Twilio Interconnect locations selected by you. See connection bandwidth and location options listed below.

For high availability, we strongly recommend connecting to at least two of our geographically redundant Twilio Exchange locations.

For example, you can select a 100-Mbps connection in Ashburn, Virginia and a 100-Mbps connection in San Jose, California to create redundant connections to Twilio on both coasts of the United States. Similarly, for Europe and Asia Pacific, our exchanges in London, Frankfurt, Singapore,Tokyo and Sydney can be used to accomplish redundancy in those regions.

IP Addresses

Your border devices (e.g. IP-PBX, SIP-PRI IAD, Session Border Controller (SBC), NAT gateway, etc.) will need to be assigned IPv4 addresses that are a part of one or more CIDR blocks (globally addressable) that your provider will announce to Twilio (your "IP Routes").

Your IP routes must be globally unique ("public IPs") - as opposed to RFC 1918 address ranges. In other words, your IP routes have to be outside of the following ranges: - - -

All services accessed over Twilio Interconnect will initiate from Twilio's IP routes. You will see them announced via BGP. You must allow all of Twilio IP routes and ports on your firewall.

You will need to add Twilio's IP routes to the access control allow list on your firewall to allow your and Twilio's platform elements to talk to each other freely without getting blocked by firewall or other security rules.


VPN Gateway

A router or firewall device supporting IPSec VPN connecting two or more networks together using security protocols such as IPSec.

Letter Of Authorization (LOA)

A document allowing the data center operator to create cross connections on behalf of the LOA originator.

Meet Me Room (MMR)

A special part of a data center where tennants can have interconnections and exchange data securely and privately. This is usually done by creating a direct patch (fiber or copper) between tenants patch panels once an LOA has been issued to the data center provider.
