About the Client


CallPage is a leading provider of callback technology in Poland, serving clients across various industries—from e-commerce to service sectors. As a rapidly growing SaaS company, CallPage requires a voice infrastructure that can match the pace and quality of its own solutions.


Beginning of the Partnership


Our collaboration began on a small scale—with a pilot implementation of a basic SIP Trunk and limited numbering. The client was acquired through our direct sales team. Even at this early stage, call quality and deployment flexibility were critical factors.


Over time, CallPage gradually expanded its cooperation with PLFON. After successful testing and a positive evaluation of system reliability, the company decided to migrate its entire voice infrastructure to PLFON, including all numbers previously serviced by one of Poland’s largest telecom operators.


Currently, we provide:


   • SIP Trunk with full support for incoming and outgoing calls
   • Polish landline (FIX) and mobile (GSM) numbers
   • International numbering, supporting CallPage’s global reach
   • Comprehensive technical and advisory support for scaling and optimization


Benefits for CallPage:


   • Full independence and control over their voice infrastructure
   • Greater flexibility in managing international operations
   • Improved customer service across multiple markets
   • Simplified numbering and reporting management
   • Support in further expanding services in a global model


Client Testimonial


“PLFON is not just a telecom operator – it's a technology partner that grows with us. From the initial testing phase to full migration and implementation of international numbering – at every stage, we could count on full support and a deep understanding of our needs.”
