[Talk to an expert](https://telnyx.com/contact-us)[View pricing](https://telnyx.com/pricing/elastic-sip) Get started in the [portal](https://telnyx.com/sign-up) ## 230+countries for international SIP trunking ## 500M+SIP calls processed monthly ## 7M+Active phone numbers managed globally **WHY TELNYX** ## Carrier, not reseller. Most SIP trunking on the market is resold. Platforms buy capacity from tier-1 carriers, mark it up, and pass the cost and the finger-pointing to you. Every layer between you and the network takes margin and adds a party to blame when something breaks. Telnyx owns the switch. The price, the call quality, and the single point of accountability all trace back to one fact: we are the carrier, not a layer on top of one. “We’ve ramped from hundreds to hundreds of thousands of calls per day with customers without experiencing any issues from Telnyx. It’s been seamless.” Benjamin Gleitzman CTO and Co-Founder FEATURES ## Enterprise Voice Higher answer rates start at the carrier layer. Because we own the network, your calls go out verified, not blocked, and clear on HD voice. * HD Voice Wideband codecs including AMR-WB for clearer conversations on both the customer and agent legs. * Branded Calling Your brand shows up on the recipient's screen, so customers know who is calling before they answer. * STIR/SHAKEN A-level attestation issued by the carrier, so caller identity is verified end to end rather than inherited. * CNAM Caller name presentation managed at the carrier layer for consistent, trusted display. * Spam protection Outbound voice profiles protect your traffic against fraud and spam before it leaves the network. * Voice Integrity Reputation monitoring and remediation to keep your numbers from being flagged as spam. Security ## End-to-end encryption Built with security at the core, our infrastructure protects customer data with encrypted, monitored, auditable interactions. It meets the highest industry standards so you can confidently protect data and maintain regulatory compliance.
