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.
