The Design and Implementation of a Schedulable Passive SIP-based Conference Call

VoIP technology is one of the important applications of the network. In addition to using traditional PSTN telephone, people can choose favorable VoIP telephone because of the Internet popularization and High speed Internet.
Conference is one of the functions of the VoIP, but not every server supported it. Such as OpenSIPS server we use in NSYSU, didn¡¦t supported it. But FreeSWITCH Server has it. Therefore, for solving this problem, I combile two Servers. Then OpenSIPS can use the Conference function.
In this paper, we discuss how to combile OpenSIPS and FreeSWITCH. Besides, I have designed a WEB page interface to simplify the procedure to use conference. By this interface, the users can use it to set the timer to start conference. When the timer is up, all of the participants will receive a conference call. After picking up the phone, the users can enter conference.
