Abstract: For the special telephone communication needs of broadcast and TV, we discuss how to implement diversiform services in VoIP systems based on Session Initiation Protocol (SIP). A new method based on SIP-B2BUA is proposed and then we implement it. First, a B2BUA component is designed and implemented. The component not only can do the basic functions of a B2BUA, but also has a smart dial-plan and an API of application modules. Second, it is discussed that the B2BUA call-processing ability extends for more diversiform services by the dial-plan smartly and application modules. The diversiform service includes callback service, Auto Call Distribution (ACD) and other call features of IP-PBX. Finally, we draw the general way out to implement diversiform services based on the B2BUA component.
