I'm trying to use a VOIP Service to allow me to make and receive calls in "Australia" (as this is where I used to live...)
To allow me to do this, I have to disable SIP ALG on the router, but I don't see any options for this in the router settings.
Does anyone know if this is even possible?
Sorry for responding on an old thread but thought I need to correct the wrong advice given here.
SIP ALG wont be blocked by many ISPs hence there's no need to unblock anything.
In other words you don't need to buy any other specific router.
