[about using a pair of wires in an Ethernet Cat 5 cable for phone]

I'm not saying it won't work and it may be the cheapest way to go, but
a Wiring Pro wouldn't do it that way.

It would likely work, but at what quality? Even with twisted pairs, there
will be some cross talk between them and the question becomes, "How much
can you tolerate"?

For phone users, this cross talk will show up as hiss and other noise in
the call. Depending on how much is introduced, this may not even be
noticable, or it might be downright annoying.

For data, the cross talk will show up as data errors which will only be
noticable as a slow-down in network traffic (as packets with errors are
resent).
