Why is my DSL working and my phone is not?

I have 1 phone line in my house other then my DSL line, they are both dedicated lines coming from the interface where the phone enters the house. When I first got DSL the phone man put a DSL filter directly on the DSL line directly after the interface. But I still experience loss of my phone for days, yet my DSL still works. Anyone have any answers before I call the telephone company ?

your DSL and phone need diffrent things to work.. if there is a short, or open your phone will stop working, while the DSL signal can still come thru...

bring a phone to the NID and see if you have dial tone there.. if you do not, then the trouble is outside and you need to call your local phone provider... if there is dial tone, then you need to determine where inside your home the problem is.. most likely it will be a defective phone, or broken wire if the trouble is inside your home..

Let the expert handle this problem, call your phone company. There could be a various reasons why you have no dial tone. Copper pair is bad, line issue, drop box issue ect... The phone company can run a test to find this out alot easier than having a bunch of answers from who ever.
