   I take exception with your reply! While technically true, in this case
we were clearly talking about a battery powered telephone therefore we're
talking about pure DC with no AC. Therefore phase, frequency and impedence
are irrelevent. Throwing in the talk of impedence just to show off is only
confusing the issue. The orginal poster that thought voltage didn't matter
clearly doesn't clearly understand electricity and I didn't won't to
confuse him further by introducing AC and it's effects.
