I discussed this with Alex Balashov off-line, and he answered my
questions:

<div>Yes, apparently this is a bit array: <a
moz-do-not-send="true"
href="https://en.wikipedia.org/wiki/Bit_array" class="">https://en.wikipedia.org/wiki/Bit_array</a> and
a value of 3 = 1+2.</div>

<div>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.</div>

This is when the sip message was sent from a.b.c.d and the Via
header has x.y.z.w. if you get a pcap with the request, we can check
and see if the test is true for it.<br>
<br>
On the other hand, you should use
set_contact_alias()/handle_ruri_alias() instead of
fix_nated_contact() (see how default kamailio.cfg does it) -- it is
safer for such cases and avoids getting in troubles with devices
that are strict in checking if the r-uri is the contact they set
previously.<br>
