XIAMEN, CHINA/Austin, TX – November 25, 2025 — Yeastar, the world’s leading provider of Unified Communications (UC) solutions, today announced the successful completion of SIP trunk interoperability testing with Telnyx, a global carrier and communications platform provider. The compatibility ensures that Yeastar partners and customers can seamlessly connect Telnyx SIP trunking services with Yeastar’s PBX and UCaaS platform for reliable, high-quality voice services.

This partnership marks a further collaboration following our initial US partnership, with Telnyx now ITSP-certified in the UK, Ireland, France, Netherlands, Poland, Australia, Saudi Arabia, and the United Arab Emirates.

The verified integration ensures that Telnyx SIP trunks perform optimally across Yeastar’s on-premises, cloud, and hybrid deployments, supporting high-quality audio, secure communication, and smooth provisioning.
