IP Telephony has become a hot topic in the last few years. There are currently 2 major protocols for signaling IP telephony, namely SIP and H.323. The first version of H.323 has been published in 1996, whereas SIP is much younger. Since it is probable that both signalization protocols will coexist for a certain time, there is a need to port existing H.323 systems into a SIP environment. We propose in this paper a solution for porting a Quality of Service Architecture, namely the Resource Management Architecture, from H.323 to SIP. As an introduction, we provide a short overview of both protocols H.323 and SIP focusing on the call setup procedure and the capability exchange process. We then propose a solution for this concrete problem as well as technical possibility for implementing the porting of the architecture from H.323 to SIP.
