companies such as IBM and shared amongst users. Software was then considered an enabler for the hardware, around which the business model of these corporations was built. Software was provided with source improved and modified; this was therefore the very early seeds of open source software. However, as hardware became cheaper and profit margins eroded in the 1970s, manufacturers looked to software to provide Ekiga, you can call anyone who is registered to the public SIP provider and uses SIP software or hardware. You can use the online address book of Ekiga to find the SIP addresses of other Ekiga users. It
