Intellectual mobile terminals (or users) of next generation wireless networks are expected to initiate/Establish Voice Over IP (VoIP) calls using session set-up protocols like H.323 or SIP (Session Initialized Protocols). To provide quality metrics of video conferences, telemedicine and other Voice over BroadBand telephony (VoBB) applications. In this paper, the authors analyze the performance of the H.323 call setup procedure over the wireless link. They used to call modes of operation over heterogeneous networks. The proposed model application layers in the RTP Control Protocol and Real-time Transport Control Protocol (RTCP) protocols used in two different modes of call established. Initiate services through VoIP used for H.323 control packets. Their analytical model provides that the VoIP call set-up performance, jitter and delay in peer to peer networks.
