The Russian telephone number +7 940 743-81-11 is being used in a wangiri scam. Wangiri is a Japanese term meaning one-cut. It translates to this scam because the scammers make a one-ring call to mobile phone numbers and then cut off.
This is in the hope that the receive of the call phones them back. Anyone that does so will immediately be re-directed to an international premium rate number. Avoid accruing large charges on your phone bill by not phoning back the number +79407438111
