Can anyone please give me a "Hello World" example of setting up a SIP trunk in FreePBX between 2 Asterisk servers on the same network (LAN, no NAT, no firewalls)?
I tried this:
Add SIP trunk:
Did the same on the other server (just replaced host IP address).
sip show users and sip show peers seem ok on both systems.
However, when I place a call via SIP from one server to the other and I enable SIP debugging in Asterisk, the "receiving" end complains about:
SIP/2.0 407 Proxy Authentication Required
(but I never setup authentication for this peer; I want to Keep It Simple for now)
What am I missing?
