04 October 2007

By 2012 there will be 435 million mobile phones in circulation which
can use session-initiation protocol (Sip), it has been suggested.

report by market researcher Informa Telecoms & Media made the claim
after it was found that sales of Sip mobile phones will hit 275 million
this year.

This confirms the growing importance of internet
telephony in both the consumer and business spheres, as Sip-enabled
phones can allow connection to IP private branch exchanges (PBXs) and
voice calls over the web.

So by using phones which can connect
to VoIP via the Sip signalling protocol, callers can save on their
bills and take advantage of IP PBX functions, such as auto attendant, unified messaging or Asterisk Dialplan.
