Cost-efficient, High-Performance Open Source SMSC
PAiCore’s SMSC empowers SMS service providers with a high throughput, feature-rich messaging platform that boosts profit margins through full protocol interworking, including reliable HTTP and/or SMPP to SS7 conversion. Unlike closed-box solutions, our open source architecture offers flexible realtime SS7 parameter control via GUI or APIs, allowing customers to optimize delivery & costs.
In addition, PAiCore’s CT Edition SMSC is well suited for operators seeking to modernize legacy messaging infrastructure with a flexible, future-ready platform, providing full ownership and customization of the SMSC, while enabling innovation from within the operator, thus reducing reliance on rigid vendor models.
Built to handle over 100,000 TPS, our SMSC supports modern protocols such as SMPP, HTTP, SS7/SIGTRAN, Diameter for 4G/LTE, with others like SIP for IP-SM-GW capabilities and HTTP/2 for SMSF/5G capabilities soon to be added, making it a highly adaptable solution for current and future messaging demands.
Our SMSC is backed by high quality 24/7 technical support , which gives our customers the peace of mind that they are not only enjoying a powerful and flexible product with no hidden transactional costs or limiting licenses, but that they can also have access to a capable team that can help them with the initial deployment, training and day-to-day operations as/when needed.
