- Abstract
- Since SIP has been proposed and standardized in IETF, it has been one of major signaling protocol in internet telephony service area. Since SIP has been selected as a base protocol in 3GPP, ITU-T, there have been several kinds of new featured services proposed by extending SIP. However this kind of new featured services requires some service-specific extensions on the signaling protocol. In other words, it is required to upgrade or replace firmware of end user devices for accommodating each new service. In this paper, we introduce a way of providing conference service to conference-unaware SIP UAs.
