Ward Mundy over at Nerd Vittles has a great post today about SIP security. It’s entitled The Incredible PBX: Adding Remotes, Preserving Security. If you run an Asterisk based PBX you should probably read this. Now!
Ward’s advice really rings true (sorry for the telecom geek pun, it couldn’t be helped!) His “Baker’s Dozen SIP Security Checklist” makes perfect sense. That doesn’t mean that I can’t add my own two cents.
