Who's on the phone?

As a matter of fact, yes he is!

Former Doctor Who actor Tom Baker is to be the voice of a talking text message service for three months.

He replaces BT's computerised voice which currently translates texts into voice messages on a landline.

Baker, 72, who also narrates sketch show Little Britain, was chosen for his instantly recognisable voice.

So this would be BT's first regeneration?

(For what it's worth, I'm running the hospitality suite at Gallifrey One, a Doctor Who convention.)
