On 25 November 2025, in Xiamen, China, and Austin, Texas, Yeastar, a global leader in Unified Communications solutions, announced the successful completion of SIP Trunk interoperability testing with Telnyx, a global provider of connectivity and communications platform services.
This compatibility allows Yeastar partners and customers to integrate Telnyx SIP Trunk services effortlessly with Yeastar PBX and UCaaS platforms, ensuring reliable, high-quality voice calls. Telnyx, now certified as an ITSP in the United Kingdom, Ireland, France, the Netherlands, Poland, Australia, Saudi Arabia, and the United Arab Emirates, is expanding its partner network.
The verified integration ensures optimal performance of Telnyx SIP trunks across Yeastar on-premises, cloud, and hybrid deployments, with support for high-quality audio, communications security, and seamless configuration. In addition to SIP Trunk, Yeastar has validated compatibility for SMS and eFax services, ensuring consistent delivery of messages and faxes across its platforms.
“Our partners’ success remains a top priority,” says Arya Zhou, Head of Global Sales at Yeastar. “This interoperability strengthens the ability of Yeastar and Telnyx partners to deliver reliable voice deployments, simplify implementation, and meet diverse customer requirements across different environments.”
“Our vision is to give businesses more choice and control over their communications,” adds Darren Laurie, Head of Partner Sales at Telnyx. “Together, we enable partners to deliver unified voice, contact center, and collaboration experiences that are reliable today and ready for the next generation of intelligent communications.”
The Yeastar team supports businesses and integrators in assessing their needs, selecting an architecture, and preparing for deployment.
