Nope, at least not in the US.

Looks like a UK phone jack

I have several from various visits overseas

Here in Oz, my beotalk simply plugs into a phone line splitter so that the beotalk and the beocom share the same cable

i guess thats a no then. Thanks everyone I'll stop trying to find it. My mistake.

Mine has a black splitter with a socket for the BeoTalk with a computer type socket (like the one above) and a socket for a phone line. 

Thanks Peter. Mine has a black splitter with 3 x RJ11 sockets for APP, POWER and LINE

The plug marked with a * on the picture is a Danish standard phone plug. Today it is quite common to use a RJ11 plug but when BT1100 and BT1200 was launched the most used plug was as shown in the picture.
