Query: Perfect for my uses

Using this with Ooma VOIP and it's great so far. Not a problem at all. Pretty clear sound considering VOIP. I am getting a new phone soon (my 2-line Panny is very old), so that also could help. But no matter, this is a very good piece of gear (though I have only had it a month). Replaced an aging amp/headset.
