Creditors can continue to contact you until your case is filed, and the Automatic Stay goes into effect. The Automatic Stay is the barrier between you and your creditors, and prevents creditors from making any contact with you.
Have you retained an attorney in CO? If you have, ask the attorney if you can refer all creditor calls to his or her firm. That is my standard practice in Georgia.

I disagree that the automatic stay stops creditors from calling you. Once the stay is in effect they will call to ask you to reaffirm your debt to them which would take it out of the bankruptcy proceedings. These calls will drop of after you make it clear your bankruptcy applies to all your debts without exception.
If your creditors call you after you file a bankruptcy, contact an attorney who knows both the bankruptcy law and the Federal Debt Collection Practices Act because they are liable for improperly contacting you once the automatic stay goes into effect. If you have checked the box that you wish to "reaffirm" a secured debt, such as your home or a car, then they may mail you a reaffirmation agreement, which you may sign and send back.
However, be clear, the automatic stay of bankruptcy unequivocally means that they must stop contacting you. Some attorneys argue that the creditors are allowed "one free call" to find out after you file. But, the better view is that once the bankruptcy is filed, the automatic stay goes into effect. Find a good debtor's attorney in your jurisdiction because contact post filing means damages for you.
