Stephan, I completely agree, Sonic Walls are not suitable for VoIP (that was someone else who wrote that BTW).
Actually, IMHO SonicWalls are barely suitable for internet access, never mind VoIP. Their ability to track state is very limited even for regular internet browsing and UDP is completely broken. As I mentioned before, this seems to be a common thing with proprietary firewall devices of many different kinds. Ironic that the most popular devices are the ones with the flashy interfaces but broken firewall implementations. Does anyone else see a parallel with OSes? ;) John On Tue, 2007-11-13 at 08:25 -0500, Stephan Monette wrote: > I don't know about you John, > > But I have a lot of customers who had tons of problems using the > SonicWall for VoIP using IAX2 signaling.
