T-2 Becomes the First Certified Yeastar SIP Trunk Provider in Slovenia

T-2 joins the Yeastar ecosystem, offering certified SIP trunk connectivity and expert support for businesses using Yeastar IP-PBX systems.

LJUBLJANA, SLOVENIA / XIAMEN, CHINA - August 24, 2026 - T-2 has become the first and currently only provider in Slovenia to be certified by Yeastar to provide SIP trunk connectivity for Yeastar IP-PBX systems. The certification confirms the compatibility of T-2 voice services with Yeastar Cloud and P Series IP-PBX systems.

Yeastar is one of the world’s leading providers of IP business phone systems, with its solutions used by businesses and integrators worldwide, including in Slovenia. With the certification, T-2 has become part of the Yeastar ecosystem as a certified SIP trunk provider.

When configuring a Yeastar system, users can select T-2 directly from the list of supported providers, with the required settings automatically pre-filled. This simplifies the connection process and reduces the risk of configuration-related issues.

The certification is also particularly valuable for companies whose Yeastar systems are installed or maintained by external integrators. These integrators can continue to manage the PBX and its configuration, while T-2 provides the connection to the public telephone network. Companies therefore do not need to change their existing integrator in order to choose a certified SIP trunk provider.

“Certification is an important confirmation of the technical compatibility of our voice services with Yeastar solutions. At the same time, it gives our customers and partners a simpler way to establish a SIP trunk connection.” said Gorazd Zorič, Head of Technical Solutions Development for Business Customers at T-2.

“Working closely with local telecom operators is an important part of expanding the Yeastar ecosystem. Through T-2’s certification, we provide end customers and channel partners with a validated SIP trunk integration for simpler, more reliable deployment, enabled by close technical collaboration.” said Arya Zhou, Head of Global Sales at Yeastar.

T-2 also has certified specialists with expertise in integrating Yeastar solutions. In addition to providing SIP trunk connectivity, T-2 can therefore offer professional support in connecting Yeastar PBX systems to the public telephone network.

T-2’s certification is also visible directly within the Yeastar ecosystem, where T-2 can be selected from the list of supported providers. This also increases T-2’s visibility among international customers and integrators looking for a SIP trunk provider for Yeastar solutions in Slovenia.
