Research points to continued growth in SIP trunking market


Recent research has identified strong on-going worldwide growth prospects for session initiation protocol (SIP) trunking; a key mechanism which enables firms to transform their conventional business phone systems to facilitate the sending and receiving of signals via internet protocol (IP) telephony.

The research, by market analysts, Infonetics, reveals that the general sector of which SIP trunking is a major part – that of session border controllers (SBCs) – achieved a total global value in 2010 of $271 million; representing an annual growth rate of 45%.

Astonishingly, Infonetics predicts that this value will increase to over $1 billion by 2015. The research company attributes this anticipated growth to increasing demand among businesses for IP telephony; particularly, business VoIP (voice over internet protocol).

The corollary of this, according to Infonetics, is that SIP trunking will remain the chief application for SBCs until at least 2013.

Infonetics also identified the ability of SBCs to adapt to increases in business scale as being viewed by service providers as one of the most valued attributes of the technology.

In related research, Infonetics has forecast that the global VoIP market will rise to $76 billion by 2015. Although VoIP is acknowledged as conferring several advantages on a business, including reduced phone costs and easier business phone systems management, Infonetics argues that this growth in VoIP adoption will be further stimulated by two main factors.

Firstly, Infonetics says, VoIP growth will be encouraged by the capacity which SIP trunking has for facilitating IP telephony without the need to decommission existing business phone systems that are based on traditional private business exchange technologies.

Secondly, it points out, more firms can now have access to IP telephony without the need for exorbitant capital expenditure, thanks to the availability of hosted VoIP services provided by a remote business VoIP provider or VoIP reseller.
