I discussed this with Alex Balashov off-line, and he answered my questions:
A flag of 3, I don’t understand. I read the documentation
<http://kamailio.org/docs/modules/4.4.x/modules/nathelper.html#nathelper.f.nat_uac_test>,
and there is a 1,2,4,8,etc… So, I’m guessing that a flag of 3, means 1+2?
Yes, apparently this is a bit array: https://en.wikipedia.org/wiki/Bit_array
<https://en.wikipedia.org/wiki/Bit_array> and a value of 3 = 1+2.
If #1 is true, then "the "received"
test is used: address in the “Via” header is compared against source IP address of
signaling”
I don’t understand this test, as I’m pretty sure that the 200OK that’s getting re-written
is properly constructed. I guess I’m trying to understand when one would want to use this
test?
Although we weren’t able to come up with an example for this test, it does not seem to
apply to my environment. Updating the flag to 1 solves my issue.
Thanks!
