<tt>Hi Henk,<br>
I checked that, and that's not the proper way to add that.<br>
You should go in constant.yml, under kamailio.lb.log or
kamailio.proxy.log (depends where you want to add the field) and
add the new info there under "request" and/or "request_init"
and/or "response", for example:<br>
<br>
request:<br>
- R=$ru<br>
- ID=$ci<br>
- CT=$ct<br>
- UA='$ua'<br>
request_init:<br>
- M=$rm<br>
- R=$ru<br>
- F=$fu<br>
- T=$tu<br>
- IP=$pr:$si:$sp<br>
- CT =$ct<br>
- ID=$ci<br>
- UA='$ua'<br>
- DESTIP=$Ri:$Rp<br>
response:<br>
<br>
<br>
<br>

<p>Hi Daniel,</p>
I have read the warning, so I changed kamailio.cfg.customtt.tt2
and did <b>not</b> make a tags_header.customtt.tt2. This time
with the $ct variable.<br>
As [%logreq -%] is expanded to R=$ru ID=$ci UA='$ua' I added the
<u>new</u> CT=$ct with escaped quotes and ; as terminator as
specified:<br>
<br>
<tt>[% argv.service='proxy'; PROCESS
'/etc/ngcp-config/templates/etc/kamailio/tags_header.tt2' -%]</tt><tt><br>
</tt><tt>[% # Add here your customizations to parameters
evaluated in file kamailio/tags_header.tt2 -%]</tt><tt><br>
</tt><tt>logreq="R=$ru ID=$ci <b>CT=$ct</b> UA=\'$ua\'";</tt><tt><br>
</tt><tt><br>
</tt><tt>#!KAMAILIO</tt><br>
<br>
So I think exactly as specified, but no result, as the first log
in the generated auth.cfg still is <br>
<tt>xlog("L_NOTICE", "Extracted caller info from PAI,
subscriber=$var(realm_user)@$var(realm_domain) - </tt><tt><b>R=$ru
ID=$ci UA='$ua'</b></tt><tt>\n");</tt><tt><br>
</tt><br>
I can also change constants.yml, or will this be overwritten by
an upgrade?<br>
<br>
Regards,<br>
<br>
Henk<br>

<tt>Hi,<br>
have you read the ATTENTION warning at the beginning of
tags_header.tt2 ?<br>
You can find there how to change it.<br>
<br>
Also, please DO NOT change the IP= , but rather ADD a new
parameter like CT=$ct<br>
<br>

<p>Hi Daniel,</p>
<p>It looks I have to overwrite logreq from tag_header.tt2,
but if I add the following line in kamailio.cfg.tt2 and
build the configuration it does not have any effect:<br>
</p>
<p>logreq="R=$ru ID=$ci IP=$ct UA=\'$ua\'";<br>
</p>
Any advise on what to change exactly?<br>
<br>

<tt>Hi Henk,<br>
you can either block the call by User Agent or you can
print out the Contact header in the log, if you want.<br>
You can use the "$ct" variable in the kamailio.cfg<br>
<br>
Cheers,<br>

<p>Hi all,</p>
<p>I'm using fail2ban and ipset-blocklist to protect my
Sipwise system. But lately scanners are not detected
by fail2ban anymore, as they are using local or random

<p>So only the contact header contains the real IP

<p>So this cannot be used for fail2ban. Is there a way
