received collect call from 214-800-9812 - thought it might be someone I know so I accepted - caller wanted me to call his mother at *72 214-397-9517 he said the extention was 72 but I had to dial *72 first - I hung up knowing this was some kind of attemped con - what kind of con I don't know yet - I think it has to do with long distance calling fraud by keeping the line open after it has been forwarded.
