Avoid the One-Ring Phone Scam

Be aware and don't fall victim to a phone scam known as "The One Ring Scam" or "Missed Call Scam".

The Better Business Bureau has issued the following alert:

How it works:

  • Your phone rings once or twice, just enough to show up as a missed call from an unknown or international area code.
  • No voicemail will be left and if you try to call it back, either no one will answer or you will only hear a weird noise on the other end.
  • Victims are later billed for the incoming international call if they answer and the premium service charge. In some cases, crammers may try to avoid detection by only adding a small charge.

If you think you've fallen for the scam, immediately notify your phone provider and keep an eye on your phone bill.

Similar to email, if you do not recognize the source, just ignore it.

Telephone System Upgrade in February—No Outage Expected

The campus telephone system will be upgraded to a new software release in February. The work will extend over several days during specific evening maintenance windows. Each component of the system will be upgraded and monitored 24 hours before moving to the next component. This maintenance does not impact VoIP, Voicemail or IP Contact Center services.

The work will be performed February 17–21 and February 24, 2014 between 9 p.m. and 5 a.m. There should be no change in telephone service during these maintenance windows with the exception of midnight Friday, February 21, when there will be a brief delay (less than 10 seconds) in dial tone. Calls in progress will remain connected.

For questions about this upgrade, please contact (734) 764-HELP or 4HELP@umich.edu
