TRANSip Enhanced Services

AS-SIP Support

TRANSip offers support for the Assured Services Session Initiation Protocol (AS-SIP). AS-SIP is a defined set of SIP signaling standards incorporating DoD Assured Service functionality, including MLPP for establishing communication with resource priorities, ensuring system and network access and control, and providing precedence and preemption policies to assure connectivity for command and control. The level of interoperability between a TRANSip-equipped REDCOM system with AS-SIP and traditional telephone networks is second to none.

Number and Feature Portability

TRANSip’s unified design creates an easy transition to the IP world by allowing subscribers to retain or transfer their numbers and features. IP subscribers can still benefit from standardized tones, announcements and other legacy features currently available to residential and business customers.

Call Detail Records

TRANSip collects and processes IP and legacy call detail records. Integrity of data collection (for all subscribers) is achieved through a powerful integrated control that provides a single interface and format for both TDM & IP usage.

Flexible Routing

TRANSip incorporates flexible IP and PSTN trunking schemes including alternate routing and emergency rerouting that maximize network efficiency, meeting Quality of Service criteria and ensuring successful call completion.
