i did not answer but there was a voicemail left.

Can you please elaborate?  Which debt collector?  What did the message say? You can help identify this caller as a legitimate debt collector or potential scam by giving us a bit more info.

calls 1 time every 7 to 10 days. 3 months now, Says they are "ABA" and i owe a medical debt from 15 yrs ago.

They identify themselves as Hollis Cobb attempting to collect a debt.  The had semi-detailed information about a doctor’s visit for my son.  When I called the doctor’s office our account was up to date and clear.   No outstanding payments and nothing sent to collections.   Be careful with this one.

Hollis Cobb is a debt collector.

You will need to send them a certified, return receipt debt validation (by law they have to go back to the original creditor to prove you owe the debt), cease and desist calling, or "not me" letter (this will be the best money that you have ever invested).  Also send it first class mail in case no one will sign for it.  Make a notation of that fact at the bottom of the letter.  You also need to report them to the proper agencies to which I have provided links to.  Then you need to go out and get a consumer lawyer to sue them on a contingency basis (no money out of your pocket) and let them pay you for the harassment.  If everyone did these three things, these crooks would be bankrupt, and we would all be the richer for it.  Use these web sites to find an attorney in your state that will probably take the case on a contingency basis (no money out of your pocket up front):  http://www.consumeradvocates.org/

It is incumbent upon them under the law to prove that the debt exists and that you owe it, and (this is the important part) that they have the legal right to collect it.  You are not obligated under the law to prove that you don’t owe or that it is paid.  

Federal law (FDCPA) requires them to send you a letter, email, or text (postmarked in the case of a letter) within 5 days of their first contact that contains their name, physical address, the creditor’s name, and the amount of the alleged debt. Unless they have communicated it to you verbally at the beginning of your conversation. It also must contain the “mini-Miranda” telling you that it is an attempt to collect a debt and that all information will be used for those purposes. The one other important thing that this communication must also have in it is that you have a right to dispute the debt within 30 days of receipt of the letter and if you do so, all collection activity must be stopped until the debt is verified. If and when you get that communication you should immediately send that debt validation letter by certified, return receipt mail.

First, you should make a complaint at this Federal Agency, and while there you should also read up on how debt collection is supposed to work as well as what your rights in this matter are: https://www.consumerfinance.gov/

Also file a complaint with your State Attorney General's office.
