[arm-allstar] Setting

[David McGough]

Bill,

VoIP spammers Internet are trying to make SIP phone calls through your 
node!

You should block general SIP access using a firewall. Only allow 
SIP connections to/from you SIP phone provider and/or other known IP 
addresses.

This scenario is a constant problem on the Internet these days.  ANYTHING 
ports that are left open to the Internet will get probed/attacked.
