FutureComm 2010: SIP Server Applications on Embedded Platforms
2 likes549 views
This document discusses SIP server applications on embedded platforms. It begins with an agenda and overview of modern communications including IP phones, video phones, and soft phones. It then discusses using a SIP server on embedded systems to provide PBX functionality, address challenges of limited resources, and provide features like call control, presence, and media processing. Examples are given of SIP servers for devices like set-top boxes and residential gateways. The document concludes by describing RADVISION's SIP server framework solution for embedded systems, which provides core server capabilities and components while allowing for custom application logic.
