Who called from 2137108109

a call from my husband who is in texas,but this number came up as a cell phone out of ca. dead air when i try to call back

called was traveling through New Mexico

This number calls my cell phone everyday and won't say anything when I answer, but will leave strange recordings on my voice mail.  Any idea who this is?

They called me about an hour ago now.  I didn't answer and no voicemail was left.  I didn't call it back.  Going to answer next time and f**k with them.
