Who called from 5612574123

Rang once, hung up.  No message left.

No message - who the heck is this calling?
(called Ottawa, Ontario, Canada)

This call is listed as coming from Belle Glade Fl.  No Message.  One website indicated it could be from a prisoner.  We do not answer unrecognized numbers.  No message - no return call.

Once again, this is Travel Options calling me from yet another number even though I'm on the national do not call list.  They persistently called me daily from 954-656-4091 and now this number.

Travel Options in Florida has been calling me for months.  I no longer answer their calls.
