Abstract

In satellite networks, voice over IP performance is degraded by long delays and low bandwidth. Both call setup time and quality of service (QoS) for voice calls are affected. Separate studies have been undertaken for these performance metrics. In this paper, we have carried out experiments using different voice codecs to evaluate SIP call setup time and QoS parameters together. The experiments are performed on the satellite network testbed at Centre for Communication Systems Research (CCSR) at University of Surrey. The results present a comparison of different codecs, highlighting their performance.
