The general framework of our technolgy starts when a user calls. His information is filtered through a firewall and later managed by the Session Border Controller (SBC) which sends the call to the Public Safety Answering Point (PSAP). Once the call is answered, the Session Initiation Protocol (SIP)/Real-time Transport Protocol (RTP) probe forwards the RTP packets which are analyzed by the call analyzer also known as Acoustic Forensic Analysis Engine (AFAE).

If the call volume is low, calls are forwarded directly to call takers. Otherwise, an automated call taker will answer. In any case, the AFAE model analyzes the content of the calls and collects data. This information is used to prioritize calls in smart queues when the call volume is high. Then, calls are forwarded to call takers in the order determined by the smart queues.
