This report presents an investigation of the
possibilities to implement voice over IP (VoIP) in
Sony Ericsson cellular phones. The results from
this investigation show that it is partially possible
to implement such a solution. The best option for
doing so is to make use of the support for the Session
Initiation Protocol and the Real-time Transport
Protocol offered by the architecture. Another goal is
to evaluate if Bluetooth is able to handle the requirements
needed for the solution. The whole concept is
proven by implementing a prototype. Measurements
on this prototype show that Bluetooth will be able to
handle the requirements of most IP-based voice communication,
i.e., in respect to latency and bandwidth.
