Google has jumped on the internet phone bandwagon and introduced a Google Voice application for Blackberrys and mobiles that are powered by Google Android.

It is expected that preference will fall to Google’s VoIP application over eBay’s Skype and solutions already available from Microsoft and Cisco.

Google finished making initial tests on the application which allows users to make calls over the internet, read transcripts, listen to voicemails and trace users to the nearest phone using a special telephone number. Google then opened up a waiting list and invited customers to join.

Google aims to get ahead of the VoIP market by offering a wireless mobile friendly application. This comes at a time when Skype are struggling to get new customers and any new revenue from their existing customer base.

Skype’s customers seem to have opted widely for the free PC to PC option and avoided the paid for option.

Google Voice will allow users to use Smartphones to send SMS messages using the Google Voice number and manage their inboxes, which will reduce the cost of international calling enormously.

Users can also choose the types of calls that they want to make through their phone using the Google VoIP system.

Google’s advances will be making those already in the VoIP marketplace very nervous.
