Public Safety Call Processing Products


VESTA®/Sentinel® 4

Bringing the best features of these two nationally acclaimed products together, the VESTA/Sentinel 4 system establishes the new benchmark for NG9-1-1 call taking. It combines Session Initiation Protocol (SIP) call handling with advanced Cassidian Communications call control technologies to support the emergency and administrative call taking needs of PSAPs with up to 250 positions. It also includes standard telephony features, e.g., Automatic Call Distribution (ACD), one-button transfer and dynamic conferencing. Plus its flexible, open architecture often eliminates the need for a traditional PBX, reducing call center costs and easily accommodating single and multi-site (geo-diverse) deployments.

Most importantly, the VESTA/Sentinel 4 system features an all-new, highly configurable and vastly intuitive user interface, considered a foundational component of our next generation integrated, geospatial multimedia platform.

A comprehensive migration strategy to the VESTA/Sentinel 4 system is in place for Cassidian Communications customers using earlier releases of our Computer Telephony Integration (CTI) solutions. These include: Sentinel® Patriot®, Sentinel® CM, Sentinel® CommandPost™, VESTA® Pallas™, VESTA® CS, VESTA® DMS-100 and VESTA® SL-100.
