I generally agree with the prior responses, but have a few other thoughts.
First, are you a party to the lawsuit? Sounds like you aren't. I also assume that the subpoena has been directed to your cell service provider and that you have been notified of the subpoena because of some law in your state that requires such notification. Unfortunately, you didn't follow the posting instruction that requests that you identify your state, so we can't know what recourse you might have.
Second, I disagree that you cannot assert the privacy rights of others. There are many cases in which a party responding to a subpoena properly can (and, in some cases, must) assert the privacy rights of others. However, since you aren't a party to the suit or the party responding to the subpoena, you may not be able to do that in this case.
Third, I would be quite surprised if any cell service provider has NAMES of persons who called you. I've never seen names on any cell bill of mine or any of the many cell service records that I have subpoenaed.
Ultimately, the way that this probably gets resolved is that the service provider will come to an agreement with the party seeking the records to identify only those records containing a particular number will be produced with records relating to any other number being redacted.
And, as the others have said, unless you're willing to spend several hours at a law library learning both the relevant substantive and procedural law, you need to get a lawyer on board if you want to raise objections.
