Abstract

The emergence of the Voice over Internet Protocol (VoIP) services requires interconnection between different technologies. In this paper we present an embedded Session Initiation Protocol (SIP) Proxy Gateway (GW) to a Mobile Network with Forward Error Corrections (FEC). Our server registers, locates and forwards the calls of an end user providing intelligent routing for user tracking. In addition, FEC along with a Markov-Chain loss model has been integrated into the server to perform a range of tests. Results prove that under high packet loss rate the embedded SIP server GW improves the speech quality.
