Introduction

ECRIT is abbreviation for Emergency Context Resolution with Internet Technologies.

ECRIT idea arose when IP-based telephony services become more popular. Users of these services (IP-based voice, text communication for hearing disabled users) expect to be able to place emergency calls.

Unfortunately, the existing mechanisms to support emergency calls that are known from public circuit-switched telephone network (PSTN) are not appropriate to handle IP-based voice, text and real-time multimedia communications.

Therfore, IETF has developed ECRIT - the context resolution of emergency calls placed by the public using voice-over-IP (VoIP) and general Internet multimedia systems, where Internet protocols are used end-to-end. Basic requirements are specified in draft-ietf-ecrit-requirements-13.

This page contains prototype implementation of ECRIT.
