According to Sensis, 20% of all small to medium enterprises in Australia have embraced VoIP as a viable business communications strategy. Whilst the small business sector is only just beginning to appreciate the benefits of VoIP technology, medium sized enterprises have long recognised that VoIP services offer not only a substantial cost benefit, but also greater flexibility for workplace efficiencies and delivery of service. This is anticipated to rise significantly in the short term with the roll-out of the National Broadband Network, with increasing internet capability nationwide (especially in regional areas) and as more technologically advanced mobile handsets, with the capacity to engage with VoIP connectivity, become more readily available.
It is acknowledged, a priori, that businesses seek to improve their bottom line through reducing their overheads, with communications an essential element for any business. With the significant savings available on VoIP products, it makes good business sense to explore the options available and undertake in a cost benefit analysis. For those enterprises who have already engaged VoIP products, 66% have indicated that the cost benefit has been the major motivation, with 46% stating that VoIP provides lower call costs, 10% identifying the lower cost of IP PBX hardware and another 10% indicating that they had experienced lower maintenance costs with VoIP telephony.
Combine these lower overheads with the inherent portability of VoIP services, which transcends geographic location, and additional features such as calling number display, re-direction of calls, instant messaging, multiple-party conference calls, video calling and the capacity to send visual or audio files during a conversation, all of which are integral to VoIP service provision, and the benefits to business are compounded.
Savvy businesses will recognise that IP telephony is the progressive pathway for all enterprise. Not only is the internet the global medium for advertising and trade. It is now THE core network for all communications, with our copper based telecommunications network predicted to soon become obsolete in its wake.
