This paper deals with an analysis of voice over secure communication links based on IPsec. The security increases an overhead, hence requires a change in a bandwidth allocation. We deal with issues such as its calculation and the impact of packet loss and delay on speech quality. Such basic information describing the transmission path is important to enable to estimate the overall speech quality. The achieved results should help in network design and optimizations, as network operators need to maintain certain levels of service quality.
