If the Asterisk endpoint has the<br>rewrite_contact option set however, the contact host and port sent<br>back in the 200 response will be the rewritten one and not the<br>one sent by the user agent. This prevents the user agent from<br>matching its own contact. Some user agents get very upset when<br>this happens and will not consider the registration successful.<br>While this is rare, it is acceptable behavior especially if more<br>than 1 user agent is allowed to register to a single endpoint/aor.<br><br>This commit updates res_pjsip_nat (where rewrite_contact is<br>implemented) to store the original incoming Contact header in<br>the request rdata before rewriting it, and to restore the original<br>host and port to the Contact header in the outgoing response.<br><br>This is only done if the request is a REGISTER and rewrite_contact<br>is enabled.<br><br>ASTERISK-28502<br>Reported-by: Ross Beer<br><br>Change-Id: Idc263ad2d2d7bd8faa047e5804d96a5fe1cd282e<br>---<br>M res/res_pjsip_nat.c<br>1 file changed, 66 insertions(+), 10 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.asterisk.org:29418/asterisk refs/changes/25/12825/3</pre><p>To view, visit <a href="https://gerrit.asterisk.org/c/asterisk/+/12825">change 12825</a>.
