Summary:This paper deals with new proposal of a speech quality monitoring tool based on the perceptual evaluation of speech quality in accordance with ITU-T P.862 and its application in a research project investigating an impact of meteorological conditions on the speech quality in a GSM network. Every time we make a call using the GSM network the speech quality differs. This is mainly caused by the numerous factors influencing the wireless communication between the user's cell phone and the GSM base station such as weather, user's current speed or location. The latter two aspects have been thoroughly measured and discussed, therefore almost anyone can determine with ease what the attenuation of the signal is for example in the building or how the signal is distorted due to the switching between base stations caused by the user's movement. On the other hand the correlation between speech quality in the GSM network and the current weather situation has not yet been measured nor estimated. This paper tries to deal with this gap and presents one of the possible solutions to perform speech quality measurement in the GSM network using open source Asterisk PBX.
