As we've all said, turn off the ALG. On Fri, Mar 2, 2012 at 9:43 AM, Lee Riemer <LRiemer at bestline.net> wrote:

We're 100% happy with recommending Sonicwall for the customers in that price range. ?In their VoIP settings, enable "Consisten NAT" and disable all else, it will be reliable and stable. ?The NSA240 for the customers wanting high-end features, and the TZ210 for simple/cheap.
Right now we are looking at Edgewater routers that have some good VoIP- specific features. ?Haven't decided on them, but I think you should take a look. ?My rep is Kevin Asano, 408-351-7220, kasano at edgewaternetworks.com.

We have a lot of our customers installing the Cisco RV 120W, and have had great luck with it. It does have SIP ALG turned on by default, but it's an easy "click" to disable it. The router supports QOS, they're easy to find (Office Depot, for example), and they're not bad price-wise for what you get. Mark

I am in the position of needing to recommend a line of SMB (10-50 person offices) router/firewall devices that will play nice with VoIP. Specifically, office has phones (generally Cisco SPA's) connecting to remove service provider Asterisk servers. Historically, I've stayed out of the hardware on the customer side, but the growing presence of "stuff that breaks SIP" is leading me to pick a vendor. I generally am in the "don't touch my signalling" camp (read: no ALG). Is there a single vendor that is consistently good about not mucking with things too much?
