My phone records were subpoenaed, what are my rights?

My neighbors are having a dispute. One family is suing the other for defamation. The family being sued countered with a battery and rape charge. These suits are in civil court. My name was included in the initial defamation law suit along with other neighbors. My phone records have been subpoenaed. I want to know what my rights are! I can understand why my phone records as it relates to these two families are being subpoenaed, but why should my private information be accessible. This is my work phone. I have no idea what the party being sued will do with this information. Should I contact an attorney and if so what type of attorney or what should their specialty be?
