Objectives of knowledge management

1 
Peer-to-peer. The best- known peer-to-peer solution is Skype which offers free calls or 
video- conferencing between Internet- connected PCs that are enabled with a headset 
(sometimes called ‘softphones’). A service called SkypeOut enables calls to landlines 
or mobile phones at a reduced cost compared to traditional billing. This service is only 
really suited to smaller businesses, but could be used in larger businesses for some staff 
who call abroad frequently to bypass the central system.
 2 
Hosted service. A company makes use of a large centralised IP-based system shared 
between many companies. This potentially reduces costs, but some companies might be 
concerned about outsourcing their entire phone directory.
 3 
Complete replacement of all telephone systems. This is potentially costly and disrup-
tive in the short term, but new companies or relocating companies may find this the 
most cost- effective solution.
