Who called from 4128722024

Does anyone know who this number belongs to?  They have called my house several times in a row, but do not leave a message.  When i tried to call the number, i get a message that says "due to network difficulty, we are unable to complete your call".

I have been getting the same calls. I tried to Google the number, but did not get any results.  They never leave a message.

DO YOU HAVE FAMILY OR FRIENDS IN THE MILITARY?? THAT NUMBER SOMETIMES COMES UP WHEN SON CALLS FROM IRAQ.

I answered this call and it was an automated call from equitable gas.
