Despite the uncertain economic climate, investment in voice over internet protocol technology (VoIP) has seen an increase in investment over the last year, according to a new study.

An industry update published by iLocus has indicated that the number of VoIP access server licenses shipped worldwide increased by 67 per cent this year and the amount of overall VoIP traffic increased by 35 per cent, reports Web Wire.

The research firm commented that VoIP carriers are in a position where they will be forced to continue to invest in the technology.

A statement from the company said: "They have little choice, it seems. Due to the losses in landlines, wireline operators are expanding into mobile and mobile operators on the other hand are looking to leverage fixed broadband networks for voice offload or over-the-top services."

Last week, VoIP provider Skype announced that it had developed a beta version of its software which will allow mobile phone users to receive Skype and SkypeIn calls, including chat, group chat and presence facilities.
