[Asterisk-Users] IAX2 + Sonicwall

[Dr. Michael J. Chudobiak]

Hi all,

I currently have an Asterisk test server behind a TZ170 Sonicwall 
firewall / NAT box, with several DIDs.

I've found that inbound IAX2 calls don't work reliably (i.e., I get a 
busy tone) unless I enable "Use Consistent NAT" in the Sonicwall. This 
feature is poorly documented by Sonicwall, so I thought I'd pass it along.

Has anyone else run into this, or figured out the rationale for it?
