OpenSIPS
OpenSIPS SIP proxy engineering for routing, load balancing, and carrier-grade signaling control.
OpenSIPS excels as a programmable SIP proxy for registration, routing, and load distribution. We implement OpenSIPS cores with clear script structure, database-backed routing where needed, and safe integration to FreeSWITCH, RTPengine, and SBC edges—so signaling scales without turning into an unreadable script.

Who it’s for
- • Carriers and aggregators running high-volume SIP
- • Platforms separating signaling from media
- • Teams migrating from opaque vendor proxies
Problems we address
- • OpenSIPS scripts are monolithic and risky to edit
- • Dispatcher and failover behavior is untested
- • Tracing production SIP issues takes too long
Expected outcomes
- • Modular script layout with documented routes
- • Dispatcher/load and failover validated in staging
- • Tracing and metrics wired for operators
