Rick Guyton Posted April 24, 2017 Report Share Posted April 24, 2017 FWIW, as an ex-sonicwall fan boy, run and hide from sonic wall on VOIP. The only way I've seen it work well, consistently is with an NSA series. Also, you want to enable consistent NAT, it does help.

Tuly Posted April 24, 2017 Author Report Share Posted April 24, 2017 i think the newer FW are better, (we are not pushing it, but that's what the client has) Link to comment Share on other sites More sharing options...
James Wright Posted April 24, 2017 Report Share Posted April 24, 2017 Enabling consistent NAT is turning ALG off. It's worded oddly, but it's what you want. Link to comment Share on other sites More sharing options...
Baze Posted April 24, 2017 Report Share Posted April 24, 2017 Add another vote for check the box for enable consistent NAT. From what we noticed, the older (several years that is) versions of the firmware did different things, so that is why sometimes you see conflicting docs. Other things we do are:-change the UDP timeout to 3600 (well, depending on how your phones are config'd)-turn OFF sip alg-set up bandwidth management and prioritize by IP or another method.We've also noticed many times people will turn on QoS settings thinking that will prioritize, but if I recall all that really does is just select to leave existing tags on the packets or manually add 46 and such, but it does NOT do anything in the way of prioritizing.

Tuly Posted September 12, 2017 Author Report Share Posted September 12, 2017 sorry for bumping this, i need to turn OFF sip ALG, from the info i got here is that clicking the check enable consistent NAT Turns off ALG, but other websites say that to turn off ALG it should not be checked, https://support.siteserver.com/kb/a109/sonicwall-disabling-sip-alg.aspx http://www.surevoip.co.uk/support/wiki/troubleshooting:sip_alg:sonicwall so what is it?
