Is an employer allowed to give their attorney the personal phone numbers of a former employee?

I'm in a situation where I had a non compete, but was fired. At my termination, I was not given any paperwork relating to a non compete. I was recruited by a competitor, and worked for them for 6 months. Then my former employer found out and sent my new employer and myself a cease and desist. They threatened to sue the employer if I was not fired. I was let go to avoid a lawsuit. Now, my former employer's attorney is calling me but not leaving messages, called three times today. My former employer gave their attorney my personal cell number and home number. I don't want their attorney calling me, and I don't want my former employer giving out my personal information. I need to know what my rights are as an employee.
