Telephony Engine

Our intelligent telephony engine is the beating heart of the Telnyx service: routing connections, interfacing with other networks and powering our high-performing and always-on communications products.

Anycast Delivery

Our anycast infrastructure continuously pings connections and our international points-of-presence to route calls on the path of lowest latency for the fastest, clearest calls.

Network Proximity

Our direct, private interconnects with Tier 1 carriers and cloud-providers keep calls off the public internet whenever possible, improving call quality and security.

Resilient Service

Don’t believe dubious claims of direct or reliable routing over the public internet. Our service’s stability and quality are unmatched because of our global, private infrastructure.

Set and Forget

Simple Configurability in a CPaaS

The Telnyx telephony engine is automated, intelligent and highly configurable. By building our engine on top of a private fiber backbone, we gained unprecedented control over how communications travel through our platform, and we extend that control to you. You'll find features in the Mission Control portal or through the Telnyx API like AnchorSite®, which allows you to anchor your call media at a particular point-of-presence. Manage other advanced options like SIP header parameters, channel limits, encryption type, or enabling technology prefix.

What do I like best? Ease of use of the Mission Control portal, porting and purchasing numbers and the ability to make real time changes to my DID numbers that can be tested immediately.
