[asterisk-users] Strange SIP Activity

[M Hulber]

Are these attempts to scam SIP calls through my Asterisk server:

[May 13 22:50:41] NOTICE[30888]: chan_sip.c:17295 handle_request_invite: 
Call from '' to extension '084312297134' rejected because extension not 
found.
[May 14 13:36:35] NOTICE[30888]: chan_sip.c:17295 handle_request_invite: 
Call from '' to extension '0114312297136' rejected because extension not 
found.
[May 15 12:20:29] NOTICE[3420]: chan_sip.c:17295 handle_request_invite: 
Call from '' to extension '8104312297134' rejected because extension not 
found.

I've not seen them before until recently.
