Abstract:

According to the analysis of SIP(Session Initiation Protocol), the regular expre ssion matching method is used to decode message. The pri nciple and algorithm of CDR(Calling Detail Record) synthesis are presented and a Hash method i s adopted to solve the problem of low efficiency in getting SIP CDR. The te st results from practical application of softswitching centralized monitori ng system have shown the good performance of the scheme.
