1 VoIP Evaluation Report Sample Timeline Tuesday, December 14, :13:39 GMT to Saturday, December 18, :58:41 GMT Generated on Saturday, December 18, :00 PM Total pages 17
2 1. Evaluation The Evaluation procedure is characterized by VoIP test procedures whose primary objective is to measure the expected voice quality over a long time period. The procedure runs evaluation tests periodically among the designated test point pairs, and reports the aggregated results as well as per-pair results. 2. Summary of Results Test Point Pairs Evaluated Calls MOS Codec HQ Remote Site # G.711 Timeline: December 14, :13:39 GMT to December 17, :13:39 GMT Page 2 of 17
