IP Selective Router
Many legacy Selective Router (SR) platforms are reaching end of life.
Comtech’s Internet Protocol (IP) SR (IPSR), an IP-based replacement for legacy SRs, seamlessly enables migration to full Next Generation 9‑1‑1 (NG9‑1‑1) capabilities.
Don’t get left behind. Learn more about Comtech’s support and migration solutions today.
The IPSR delivers calls to legacy and NG9‑1‑1 public safety answering points (PSAPs). It routes calls based upon geospatial data, ensuring that all current and future call types are routed to the appropriate PSAP.
Methods include traditional SR tables, Dialed Number Identification Service (DNIS), Geographic Information System (GIS), and a hybrid configuration of Automatic Location Identification (ALI) and SR tables.
Highly redundant and scalable, the Comtech IPSR supports location by value (LbyV), location by reference (LbyR), traditional ALI lookup, and ALI steering.
