My AsteriskNow server is getting hacked ( luckily only on a small scale )
I’m seeing
NOTICE[27672] chan_sip.c: Call from ‘’ to extension ‘xxxxxxxxxxx’ rejected because extension not found in context ‘default’
where xxxxx is always the same number with a veriety of prefixes i.e. 00 0011 001144 etc
Can anyone point me in the right direction to locate where I can find where these ‘calls’ are coming from and of course how to stop them
Any help gratefully received
Thanks.
p.s. No details of these attempted calls is making it into the CDR file!!!
