Today we are excited to begin exposing packet captures (pcaps) from the edge of the Twilio network. These pcaps help you to configure & troubleshoot Elastic SIP Trunks. This latest tool is available today in your account portal for all SIP Trunking calls. We will automatically generate these pcaps of the signaling for all trunking calls and keep them available for you for 48 hours. Greater visibility into Twilio’s edge helps reduce the time it takes to connect trunks to your IP-PBX, call center, SBC, or SIP server and makes troubleshooting easier.
Our goal for Elastic SIP Trunking is to make PSTN connectivity instant to deploy and effortless to scale. This began with the launch of our service with a pay-as-you-go pricing model and instant provisioning of phone numbers and trunks from the account portal. Since then we’ve added complete control over trunks …
Today we are happy to announce the general availability of Secure Trunking. This launch makes further security available on all Elastic SIP Trunks, by enabling customers to use Secure Real-time Protocol (SRTP) to encrypt media and Transport Layer Security (TLS) to encrypt signaling. This encryption allows businesses with strict information security practices to reap the benefits of both SIP trunks and cloud communications.
With Secure Trunking, SRTP is used to encrypt and authenticate the media payload of all calls on that trunk. Authentication validates that packets are from the purported source (customer or Twilio), and that the packets have not been altered during transmission. Encryption ensures that the call content has remained secure during transmission. Secure Trunking support TLS for SIP, which ensures the privacy of SIP signaling between Twilio and its customers over the Internet. TLS, the same encryption model used for secure HTTP for websites, …
Today we are excited to add further programmatic access to Elastic SIP Trunking. You can now provision, configure, and modify Elastic SIP Trunks, URLs/Domain Names, Credential Lists, and IP Access Control Lists with the REST API.
We hear from all sorts of customers interested in having more control of their trunks through a REST API, but we see the most interest from resellers and SaaS providers. I’ll walk through how these customers use different parts of the new API and the rest of the Twilio platform to build robust multi-tenant apps.
Customers using the API
A great example of a reseller is ThinkVoice, who offer SIP Trunking to their clients through a self-service portal. Brian Coyle, CEO and founder of ThinkVoice, explained why he chose to build his solution on Elastic SIP Trunks:
The Twilio Elastic SIP trunking product has given me the ability to reach a …
Today we are excited to add a feature to make it even faster to configure your load balancing and resilience strategy on Twilio Elastic SIP Trunks. We are providing this through Multiple Origination URIs, which are configurable in your account portal and through the API.
Since we first launched Elastic SIP Trunking we have offered a Disaster Recovery feature. This further helps our customers failover gracefully when their voice infrastructure is critically down, by replicating the call logic that lives in your PBX in the cloud. However, there are many nuances in between a 200 OK response and a full outage. Perhaps one of your IP-PBXs or SBCs is over capacity, or maybe you’ve lost local connectivity to one site, but not all sites.
The first use for Multiple Origination URIs is managing load-balancing with a simple interface by distributing the “weighting” across different Origination URIs. This …
Last November we announced the unbundling of our PSTN connectivity as a service. Elastic SIP Trunking provides instant global voice provisioning for your IP infrastructure (e.g. IP-PBX, SBC, UC hardware, VoIP gateway, etc). Twilio uses the power of the cloud to offer resilience, intelligent local call routing, sms-enabled trunks, cloud-based call recording, multi-tenancy, and full WebRTC support.
Since November, we have seen companies using this connectivity to provide great multi-channel customer support experiences, create engaging advertising campaigns, change the way business’ collaborate, and deliver critical alerts. In the past 3 months, Elastic SIP Trunking traffic grew by nearly 400% thanks to companies augmenting their businesses and services with cloud based PSTN connectivity.
SIP Trunking Pricing Changes
Beginning July 1st we are making two changes to our Elastic SIP Trunking prices. We are introducing a new zoned pricing model and we are lowering our North American termination price by 12.5% from …
Your employees are working remotely, from home, airports, hotels, customer locations and coffee shops. Wherever they are, they’re not in the office as much anymore. You’ve introduced tools to allow them to communicate efficiently across teams, no matter where they are. But, finding the right tool for voice communications is still problematic.
Today many PBX’s and call center’s have a softphone feature and you could deploy these software clients. But these clients are yet another piece of software for you to provision, deploy, and maintain. Worse, they often just don’t work. Remote firewalls and proxies often block calls and when calls are completed the quality is poor.
WebRTC makes life much, much easier.
WebRTC is built directly into your browser which allows you to communicate with ease. There …
