Asterisk Notice error showing as time increases

Hi guys,

I logged into my Asterisk server and I noticed this Notice error which keeps coming as the time counts. I have tried the CLEAR command but it doesnt go away.

If you read the logs carefully and use some common sense you will discovery some one is trying to register extension 208 using the remote IP address, this is brute force attack



Change the default SIP PORT 5060 for non standard port


Secure password

I thought as much. Thanks
