SonicWall NSA 240

[simonff]

Hi, I was wondering if anyone has been able to set up a SonicWall NSA 240 with their 3cx system? Outgoing calls are working fine but incoming calls work randomly. Looking at our VoIP provider it shows that its connecting on a random port and also registering more than once.

Any help would be great!

Thanks

I have not do it on a NSA 240 but on other sonicwalls before, make sure to enable consistant nat and trun off the sip alg transforms under the voip tab.
