Case Study: Viber achieves faster Push-to-Talk messaging with ScienceSoft

Viber - Customer Case Study

Viber needed a reliable partner to develop a backend service for processing and storing Push-To-Talk messages in its mobile app. ScienceSoft was chosen to help with this work after demonstrating strong VoIP expertise, with the goal of supporting smooth app usage and comfortable voice messaging.

ScienceSoft built a backend for Viber using PHP, AWS cloud services, Couchbase, SQS, S3, Linux daemons, Zabbix, and PHP Unit. The team also implemented chunked voice-message sending over a keep-alive HTTP connection to speed up data transfer, and the result was a high-grade backend that contributed to the overall product success.
