The attack came, at different times, from 3 separate IP addresses. I don't see why you would want to attack a VoIP client. Maybe the dark side knows something I don't. Recently I have seen an increase in brute force register attacks from Chinese networks. But that was on Asterisk servers. I had to block the following networks from which most attacks originated: 60.0.0.0/255.248.0.0 60.8.0.0/255.254.0.0 60.10.0.0/255.255.0.0 Most other attacks came from the US, France and Brazil. Installing fail2ban may help where a single IP tries to brute force itself into a SIP server. But that does not apply to a VoIP client. Would you mind sharing which networks your attacks came from?
