Peer-to-Peer
VoIP Services Need to Take a SIP

Peer-to-Peer VoIP services have proved to
be very popular. Skype claims to have more than 10 million users. However,
Skype and other peer-to-peer providers use proprietary technology to
deliver their services. This results in potential quality of service,
security and reliability issues, as there is no way to manage pure
peer-to-peer routing. Additionally, the ability to improve quality and
provide new services through collaboration is tough to come by in the pure
peer-to-peer environment. The limitations of peer-to-peer can be overcome
through the introduction of Session Initiation Protocol (SIP). Here
are some advantages and disadvantages to consider.
