Do we ever see the guy who speaks trough the loudspeaker in M.A.S.H.?
I'm not sure that an unidentified, nameless voice really counts as a character. More a plot device.

Has Dorian's husband 'Marcus' in Birds of a Feather been mentioned?
Alan Partridge's son- Fernando was it?- and his ex wife Carol.
I don't know if this has been said, but there's Ma Glum in the Glums, or Mr Barraclough's wife in Porridge.
Barraclough -'I've never got used to bolting these doors. I think of all of you locked in these little cells and I think of me going out of here, well going home to my little house, and my wife who's waiting for me....
Fletcher - What's the matter Mr Baraclough
Barraclough- Sometimes I wish I was in here with you lot.

If we are doing disembodied voices then how about "This is Carlton your doorman" from Rhoda.
Homer Simpsons mentioned some co-workers in the power plant I think we never get to see...a guy called Zutroy or Zootroy or something like that. I can't remember the name of the other one.
Tibor was the name of the other one. In a an episode Homer laughs at this Tibor guy calling him a complete loser...later in that episode we learn that even Tibor got promoted once, which makes Homer the only in the plant without getting promotedat least once.
