The Yorkshire stations have had that since the networking expansion started, largely used for giving different contact details (presumably to track engagement for each station). Sticks out a mile for me, not sure about the listener in the street.

I think a lot of this is down to the skill of the presenter - for example, the split links on the afternoon show on Kent/Surrey/Sussex are done very well, and although a regular listener might notice he always reads the phone number with the exact same intonation, it all sounds seamless and you really can't tell the join.

On the other hand, with some other presenters I've heard it sounds awkward and clunky, and it's quite obvious that they're playing in a recording of themselves.
