Thanks to all the replies to my question, both in TELECOM and in
private mail.  The wire people here talked to some telephone people,
and were convinced not to swap polarity.  Interestingly, while most of
the responses contained the same basic information, that Touch-Tone
phones without a full-wave bridge won't be able to generate touch
tones, about half the responses said "this is a terrible problem -
don't do it", while the other half said "but this shouldn't be a
problem"! :-)  Since we need to be compatible with existing customer
equipment, we're keeping polarity correct.

	Thanks again,
