hello,

if you look at the ip,where this calls come from, it say
113.105.153.251 ->
inetnum:        113.96.0.0 - 113.111.255.255
netname:        CHINANET-GD
descr:          CHINANET Guangdong province network
descr:          Data Communication Division
descr:          China Telecom

so if you dont know someone in china, it would be a good idea to block
this AND set allowguest=no to prevent this in future.

best regards
