What rights does my company have on a agency trying to collect on a business debt?

[darce]

I was asked by my A/P Manager to do some research on the company rights on a business debt collection. I know consumer has rights and am familiar with that but do the same rights apply to business's as well? There is a collection agency that continuously calls our business harassing employees to collect this debt, but the debt has already been cleared up with the company it self this agency is representing. The agency is still calling and getting unreasonable and threatening to me (who answers the calls) that they are just going to start calling people at home. Which I know they can not but I need something in writing so my company can work on this.
I know the company has to have some rights on this, I know they can not do anything to me or the employee's themselves but its the threats that are uncalled for. So where can I find information on this?
