interesting you say that, we were using the Sonicwall without any real config on my part for a good 6 months until it suddenly stopped incoming calls, it was only after several phone calls with our provider telling me it was an issue our end that i started to really look at the Sonicwall.
Yeah…providers ALWAYS think the problem is on the Customer side - and in their defense, it usually is - but not always.
Grab a capture real quick and it should tell you - if the system is not busy, you can sometimes watch the CLI with asterisk -vvvr and see the rejections there - but if it is busy at all, it’s too hard to catch - hence the Packet Capture.
Just in case anyone stumbles across this - asterisk -vr is only 1 level of verbosity (detail) - that will not show you TONS of messages that asterisk -vvvr will show you - for most things, 3 levels of verbosity is the minimum level that will show you relevant info in my experience.
yeah sorry missed that, and yes just spotted the dns, just resolving. weirdly it isn’t letting me change form the ui i remember there is a conf file you can edit but can you remind me of the location
After talking to Matthew, it was NEVER anything to do with the SonicWALL whatsoever - the ITSP that he is using provides their own ROUTER - all the VoIP traffic that comes and goes to them goes through their device, never through his SonicWALL - we figured this out by sending traffic with another provider to his box - his current provider, even though they are allowing outbound, are never sending inbound.
