This call is most likely an attempt to get valid numbers. Its probally a robo calling system with no message that just dials trying to find someone to answer the phone. Expect lots of scammers to call you in the future after answering the phone from this caller.
Just happened to me today too. No one spoke and after 4 attempts to get someone to talk I hung up. I attempted to call back a few times and got two error messages about all circuits being busy. This is usually the case when a telephone is setup only for outgoing calls (doesnt accept incomming connections). I am thinking this is a robo call verifying phone numbers are active or disconnected for future telemarketing , suvery, or political calls.
Been receiving repeated calls since Thursday from this and many other numbers. Now receiving calls from local cell users with numbers similar to mine saying they received a call from my number. I would recommend that you do not answer any call you don't recognize -- or if you do -- do not stay on the line long enough to have your number "captured".
