They can be used to judge the VoIP calls' behavior between IP-PBX and SIP proxy server. The SIP messages were collected in order to analyze customers’ services for promoting VoIP’s evolution.
SIP makes rapid transmission of VoIP service. It is a convenient, economical, effective and brand-new telecommunication method.
By analyzing the messages of SIP, the handshake of the signaling protocols can be further understood.
The purpose of this research is to analyze the call completion behaviors between IP-PBX and SIP proxy server by measuring message handshake time which is measured in terms of three phases. Call Setup Delay, Inter-arrival Time, and Session Duration are analyzed individually. Based on the statistics, the ratio of SIP dialed call is further discussed.
The result can help us have a better understanding on the effective messages of VoIP by SIP signaling behaviors, reflect the phenomenon of each communicative message effectively and provide reference for the designers.
