Martin Glazer commented on ASTERISK-19348:
------------------------------------------

This addition does not work for me on 1.8.20.1 It adds the line to the logs, however the line still contains MY IP adddress and not the attackers.

> Asterisk should log source IP address of incoming calls when allowguest=no AND alwaysauthreject=yes but it doesn't. It seems to be a deficiency of allowguest feature. The only log found when there is an incoming call is this which doesn't include source IP address:
> NOTICE[10331] chan_sip.c: Sending fake auth rejection for device "Anonymous" <sip:Anonymous at anonymous.invalid>;tag=as4a1b8317
> ***WARNING: source IP address in this MUST be pulled from OS network layer rather than relying on SIP Packets as spoofed source IP is not really the source IP. Better yet maybe include both spoofed source IP and true source IP in a message like this:
> chan_sip.c: NOTICE[xxxxx]: Call attempt was made from SPOOFED SOURCE IP: x.x.x.x with TRUE SOURCE IP: x.x.x.x
> ***It's best to create this log in full log file as well.
