OpenSIPS 2.0 - a programmable framework for SIP

Abstract

The new design of OpenSIPS (2.0 design) brings a radical new approach on how a SIP server is architectured, on how you can program a SIP service, on how you can scale SIP networks.

Two most important concepts are addressed by OpenSIPS 2.0:

• horizontal scalability – having a complete separation between core (SIP engine) and the routing logic (service implementation), OpenSIPS 2.0 will natively allow clustering of multiple independent cores into a single distributed service logic.
• service programming – the routing logic (service implementation) is a separate entity that can be implemented in any high-level language (python, perl, java), enabling an easy service creation (no custom configuration) and natural integration (as application) into larger service platform.

OpenSIPS 2.0 is about efficiency, about simplicity and about integration.
