- Supports consistent policy enforcement on SIP core networks
- Presents a non-disruptive NGN migration path that enables IP networks to access legacy and Intelligent Network/Advanced Intelligent Network (IN/AIN) services
- Consolidates SS7/C7 links and supports multiple Originating Point Codes (OPCs) and Subsystem Numbers (SSNs) to reduce operator costs and increase network efficiency
- Provides a future-ready solution that is scalable, reliable, easy to manage and IMS compliant
