Overview
This product has charges associated with it for seller support. Deploy a production ready OpenSIPS server on AWS in minutes. Built for ITSPs, carriers and VoIP platform teams who need class 4 SIP routing, least cost routing, load balancing and registrar capability, without days of module compilation, database schema setup and Control Panel assembly.
Why OpenSIPS, and why this image
OpenSIPS routes tens of thousands of call setups per second and powers routing cores at ITSPs and carriers worldwide. Its dynamic routing (drouting) and load balancer modules, dialog aware NAT handling make it the strongest open source choice for service provider routing platforms.
What you get out of the box
- Latest stable OpenSIPS from the official project repository
- Anti fraud defaults: fail2ban SIP scanner rules, rate limiting, authentication on, no open relay behaviour
- TLS ready on 5061 with a documented Let's Encrypt path; WebSocket staged for WebRTC scenarios
Common use cases
- ITSP routing core: prefix routing, least cost routing and carrier failover with drouting
- SIP load balancer: distribute registrations and calls across a media server farm with health checks
- Class 4 interconnect: route between carriers with per gateway capacity control
Choosing between OpenSIPS and Kamailio
Both descend from the same OpenSER lineage and both are excellent. Teams typically choose OpenSIPS for service provider routing platforms, the web Control Panel and the drouting and load_balancer modules; teams choose Kamailio for WebRTC edge, IMS work and its module ecosystem. CloudSOE publishes hardened images for both, so you can evaluate each on identical bases: see the CloudSOE Kamailio listing.
Sizing guidance
Signalling is CPU light. Evaluation: t3.small. Production routing core: t3.medium or m7i.large. Large routing tables and high registration churn benefit from memory rather than cores. Keep media off this box: RTP belongs on your media servers or a dedicated relay.
