BBC News has exclusive video to the BT/PSP calling functions.
Using a soon-to be-released camera and microphone, gamers will be able to call other PSP owners and some BT phones.
The software has been developed by BT and will eventually allow PSP users to call PCs, fixed lines and mobiles.
Initially the service will only be available in the UK and will only work on home or BT wireless hotspots.
Currently, there are around 2,000 of these situated in airports, railway stations, hotels and fast food restaurants.
