the point is, if you choose and use the right connector it will work. and yes, contractors like you use the cheapest stuff and make money on it on top of the labor.
Which is a RJ11 for phones and as I and many contractors I compete with guarantee their work saving a buck or two is not worth driving back to fix an inferior product. More than the money though is my reputation that I will not sacrifice by using cheap products.
