I'm trying to migrate from a Sonicwall to XG115 V16. I've been running two different SIP gateways through the Sonicwall from the same PBX, serving two different tenants. When I move to the XG I get one way audio problems and my SIP soft phone app on my Android can no longer register through the XG.
I tried the "system system_modules sip unload" command which didn't seem to help. The Allworx PBX automatically rewrites the WAN-bound packet's internal address as the public address for return traffic to use, and all I ever did on the Sonicwall is enable what they call Consistent NAT. Interestingly, when I effectively disabled that by telling it the public address to use was actually the private IP I got two way audio going on the desk phones, though calls would drop after a few seconds. The soft phone would register but not have audio either direction. I may be mixing up the combination of things I did, but bottom line is I need some feedback on if there are issues I'm beating my head against the wall on, or some settings I need to know about. I saw one article referring to disabling DOS setting, but did not see that in V16.
Any ideas?
