Abstract
The current trend in communication development leads to the creation of a universal network suitable for transmission of all types of information. Terms such as the NGN or well-known VoIP start to be widely used. A key factor for assessing of the quality of offered services in the VoIP world represents the quality of transferred call. The assessment of the call quality for the above mentioned networks requires using new approaches. Nowadays, there are many standardized subjective and objective sophisticated methods of these speech quality evaluations. Based on the knowledge of these recommendations, we have developed testbed and procedures to verify and compare the signal quality when using TDM and VoIP technologies. The presented results are obtained from the measurement done in the network of the Armed Force Czech Republic.
