VoIP use increasing but TDM lines remain

Businesses are unsurprisingly taking advantage of the increasing service offerings and reduced costs offered by VoIP, but are surprisingly not abandoning traditional voice lines, In-Stat reports.

The research company said that VoIP is currently used by 20 per cent of US businesses, but 44 per cent of these businesses' voice lines remain Time Divisional Multiplexing (TDM) systems.

"VoIP is particularly attractive to businesses with dispersed workforces, where long distance savings can be easily achieved," said David Lemelin, In-Stat analyst.

"However, VoIP is not typically embraced as the sole source of voice communications for the vast majority of businesses that have adopted VoIP to date."

Mr Lemelin predicts that two-thirds of US businesses will have some form of VoIP service by 2011.

Additionally, In-Stat said multiple VoIP solutions are used by 36 per cent of businesses that have adopted VoIP, with broadband IP telephony solutions resonating most strongly with smaller businesses and IP PBX with larger ones.
