# Why Test Teknoloji?

> Türkiye's only Yeastar Platinum partner. End-to-end ownership, 30+ years of continuity and the strength of locally built products.

## Why did 2000+ institutions choose us for their most critical infrastructure?

Because no one else delivers all communication — from PBX to call center — from a single source, with Yeastar leadership and thirty years of trust behind it.

- **End-to-end ownership** — PBX, call center, video conferencing, omnichannel — all from a single source. One partner and one point of accountability, instead of dozens of vendors. We integrate every leading brand for you (Yeastar, Alcatel-Lucent, Yealink, Jabra, Hellohub and more), and with our own AI assistant and call center AI agent, automation stays in-house too.
- **Yeastar Platinum leadership** — We are Türkiye's only Yeastar Platinum partner, recognized with "Customer Success Excellence" at the Yeahs Awards 2025. The world-leading technology's highest partner tier is ours.
- **30+ years of continuity** — Uninterrupted since 1994. We have ranked among Türkiye's 500 largest IT companies for years and earned back-to-back achievement awards from our technology partners. Your vendor will still be here tomorrow.
- **Data & compliance assurance** — An added assurance for regulated institutions: when required, your data stays in Türkiye, with KVKK (Turkish data protection law) compliance built into the design.

## Certifications and competencies

Our corporate certifications document quality, security and continuity:

- **ISO 9001:2015** — Quality Management System

- **ISO 14001:2015** — Environmental Management System
