Enterprise telephony services have been gradually upgraded to IP PBX functionality…
2005 was the year of inflection, when more IP PBX ports shipped than digital PBX. The original business case was predicated on the idea of saving costs, since the IP PBX used data networks and not an independently-wired digital telephone network. However, this model quickly gave way to the idea that a more flexible system – users can plug into any Ethernet port and get dialtone service – is more useful for the same investment quickly took hold in the market.
Average selling price per user has not changed much over the past decade, despite the entry of dozens of competitors and the adoption of IP technology and architectures by every digital PBX vendors.
In 2004, Siemens, 3Com and others began to promote the idea that the benefit of IP PBX deployments was to access new and advanced applications. We promoted SIP as the right, highly flexible interface and introduced a suite of applications for conferencing and presence to complement the telephony service of the IP PBX.
Now, in 2006, the key is mobile telephony. SIPquest is moving the boundaries of IP PBX control and service right into the user's pocket.
