No manufacturer really understands SIP so they do not even acknowledge that they break things by adding such 'support' into their routers, forget about fixing their implementation that was completely un-necessary in the first place. All SIP providers have a NAT traversal solution in place that simply works.  The only way to eradicate the SIP ALG plague is to mandate the usage of TLS for SIP transport in a future iteration of the SIP protocol specs. And the chance of this happening is close to zero...

I haven't found a SIP ALG in any of the home NAT routers I have, and I've accumulated a fairly large collection. Of course, there might be one there, but if so it hasn't caused me enough trouble that I've had to find it yet.
