SigScale is an open source software developer focused on cloud native signaling solutions for communications service providers' virtualized core networks. We engage with our CSP partners through sponsorship of feature additions to our fully open source stable of virtual network functions and ongoing subscription support services. At SigScale we believe in license free software and a commercial model where costs are relative to consumption of our resources not your subscriber traffic volumes. SigScale's flagship product is our 3GPP Online Charging Server (OCS) built with TM Forum Open Digital Architecture (ODA).
