In this work we propose an algorithm for efficient packet loss detection services allocation in VoIP environments. We aim to increase the final user voice perceived quality. Given a path between the sender and the receiver, the algorithm will determine the optimal location of the packet loss detector by considering a subjective voice quality measure. More precisely, by using a simplified version of the E-model, the algorithm estimates the loss detection agent location which maximizes the expected end to end subjective quality. To achieve this, beside of the proposed algorithm, analytical expressions for the prediction of the loss probability and the mean delay are provided. The proposed procedure is evaluated and validated by means of simulation.
