Re: "some people even have home VOIP systems"

ALG is know to create problems because it actually can mess with the session payload. I have an ATA at home to use the FTTC connection VoIP service, and I don't use ALG as well.

But for many users it is simpler than other methods, and often it is transparent, so they don't even know it's there. I've seen users on forum saying "you don't need to use STUN or forward ports, it works!!!" - sure, you're router has ALG enabled...
