Have dial tone, but call doesn't go through

Have dial tone, but call doesn't go through

Occasionally when making a call,we'll have a dial tone but the call doesn't seem to go through. Pretty sure it goes through on the other end, because a couple of times we've gotten calls back from call recipient who told us they got it and answered, but we hear nothing...

We have dial tone, and we receive calls. However,  when we dial  a number we just get the dial tone.
