Mostly due to UDP translation on it NAT mapping. Enable consistent NAT "suppose" to address this issue. But it can be a hit and miss with different version of SonicOS. Another issue you may come across if you can get it to work is call drop off after "X" mins cause by its DOS protection. So, test it out thoroughly if you can get it to work. Bottom line is, Sonicwall is just not very friendly with VOIP. It requires a lot of tweaking to get it to work right. If you are not using any other features like its VPN or Gateway AV protection from your TZ150, you may want to consider replacing it with a more simple firewall like the Netgear VPN firewall or the Cisco small business router.
Any phone behind the TZ150 has this same connection issue - thats Cisco 7940's and Snom 300's I've tried. 3CX soft phone does work, with tunneling enabled. Obviously, the hard phones don't have this feature. I have seen the Tunnel proxy thing that you run on a PC to get around this, but as there's no server on site there it would have to run on an end users machine; it all gets a bit messy - would rather go through the motions and get it done properly.
