+Gateway Test:
+
+A project to detect echoes in VoIP calls and evaluate the performance of analog telephony adaptors (ATAs).
+
+The Algorithm:
+
+This application uses time-stamps and speech recognition to detect echoes in VoIP calls (2 patents are pending).
+
+The caller program makes a VoIP call to the callee program. On answering the call, the callee user agent plays some audio and records the time-stamp it played that audio. The caller program on detecting the audio, plays its own audio and records the time-stamp. The callee agent notes the time-stamp when it hears audio. it also applies speech recognition to detect if it is hearing itself or the other side. 
+
+Based on the recorded timestamps and output of speech recognizer, abnormal conditions in a call such as echoes, white noise, bad audio channel, call connection and hang-up latencies are detected.
