PortaSwitch is a unified platform for telecom operators that pairs a Class 4/5 softswitch (PortaSIP) with a real-time billing and online charging engine (PortaBilling). Carriers in wholesale, MVNOs, ITSPs, and UCaaS or voice service providers use one BSS+OCS stack to manage their voice, messaging, data, and IoT/M2M services. An open REST API connects it easily to external systems. What operators get: - Self-managed tariffs and service plans: launch new rates or bundles yourself, without depending on vendor update schedules - Online charging for both prepaid and postpaid customers, including wallet and balance management and fund reservation that stops users from overspending - SIP routing on a Class 4/5 switch built to handle high wholesale call concurrency, with hosted PBX and IP Centrex services for business customers - Reseller and wholesale tiers that can run under your own brand - Automatic failover between geographically separate sites - Complete source code, provided with an unlimited license - Switch from your current platform while existing subscribers stay online Pricing comes in two models: a perpetual license paid once, with no cap on subscriber numbers, or a monthly SaaS plan charged per billable event. Deployment options include your own data center, Oracle Cloud Infrastructure, or a mix of both. Instead of a fixed minimum server count, switching and billing components scale out to whatever number of servers your call volume and redundancy targets call for.
