This application guide discusses five use cases for how operators can use a SIP Signaling Router to solve many of their next-gen network challenges.
Operators continue to deploy VoIP, SIP and next-gen networks (NGNs), but the voice-centric, softswitch architecture used in many networks today is not able to support the services necessary in today's environment. Operators can deploy a SIP Signaling Router (SSR) - a SIP proxy with enhanced routing capabilities - to create a signaling and session control framework for NGNs. Implementing SIP routing functionality in the core network enhances routing capabilities and increases service and network flexibility by relieving endpoints of session management duties.
This application guide examines the following use cases for a SIP Signaling Router:
- Enhanced application server selection
- SIP trunking
- SIP number portability
- Centralized SIP routing
- Specialized SIP proxy
