The only one I can find is the real deal for about $250.00 - I just need something I know is reliable so I can rule out customer phone sets as being the cause of line noise (e.g. phone line
sounds noisy on their phone handset, but I need to rule out the possiblilty that their phone handset is faulty). I was thinking about making something up, with a cheap small phone and
swappable alligator clips/standard jack, as I would like to be able to easily test different parts of the phone lines.
Anyone here got any better ideas?
