Case Study: O2 Germany (Telefónica) achieves award‑winning interactive telesales and increased conversions with giosg

Telecom customer experience innovation: O2 wins award with Whisbi

O2 Germany needed a more engaging online customer experience and better ways to convert web visitors into sales — their existing hotline and chat channels weren’t delivering the real-time, personalized interactions and upsell opportunities they wanted. To address this, O2 turned to giosg and implemented the giosg Conversational Marketing platform to capture, qualify and convert leads directly from their website.

giosg’s solution added a prominent yet non-intrusive CTA for chat or free callback, then synchronized calls with interactive video, co‑browsing and chat so telesales reps could demonstrate products, guide order completion and suggest tailored alternatives in real time. The platform’s end-to-end tracking and analytics helped O2 optimize the customer journey, drive sales and improve upsell/cross-sell performance — results that contributed to Telefónica Germany (O2) winning a Call Center Innovator Award for the project with giosg.
