Packet1 Ingress provides carriers with the tools to manage and provision their subscribers and carrier interconnects. Effective subscriber and interconnect management is critical for any communication carrier as it maximizes profits through selecting the cheapest carrier at the time to terminate an off-net call and allows the carrier to charge for additional features such as call forwarding, call screening, call forking, call hunting and auto attendant.

Packet1 Ingress is a SIP Application server. It functions similar to an IN network where all signalling control is sent via SIP stacks; it is also similar to transit class-5 switches. Packet1 Ingress is programmed with routes to SIP trunks and media resources and supports both SIP and Diameter. The gateway exchange provides a single control point in the IMS network and unifies multiple vendor equipment into one logical switch.
