<tt>Hello Fabian,<br>
<br>
Regarding your questions:<br>
<br>
1) limiting the number of contacts to be used:<br>
a) either keep in memory just one registration (last one) -
see the "cxx" and "f" flags <br>
<a class="moz-txt-link-freetext" href="http://www.opensips.org/html/docs/modules/1.8.x/registrar.html#id292725">http://www.opensips.org/html/docs/modules/1.8.x/registrar.html#id292725</a><br>
doing save("location","c1f")<br>
b) either keep all contacts in mem, but use only the most
recent one:<br>
</tt><tt>modparam("usrloc", "desc_time_order", 1)<br>
lookup("location","b"); # see

<br>
<br>
2) regarding the TCP timeout, it can be controlled via
tcp_connect_timeout:<br>

<div>Dear list</div>

<div>We develop SIP clients and have an OpenSIPS 1.8.0 test
server. We are bound to use TCP and frequently kill the clients
without unregistering. This leads to invalid contacts in the
location table. </div>
<div><br>
</div>
<div>It often takes a long time for an INVITE or MESSAGE to be
forwarded by the server. In syslog we see a lot of these
entries:</div>
<div><br>
</div>
<div>Oct 18 14:55:50 Debian-60-squeeze-64-minimal
/usr/sbin/opensips[11050]: ERROR:core:tcp_blocking_connect:
timeout 10 s elapsed from 10 s</div>
<div>Oct 18 14:55:50 Debian-60-squeeze-64-minimal
/usr/sbin/opensips[11050]: ERROR:core:tcpconn_connect:
tcp_blocking_connect failed</div>
<div>Oct 18 14:55:50 Debian-60-squeeze-64-minimal
/usr/sbin/opensips[11050]: ERROR:core:tcp_send: connect failed</div>
<div>Oct 18 14:55:50 Debian-60-squeeze-64-minimal
/usr/sbin/opensips[11050]: ERROR:tm:msg_send: tcp_send failed</div>
<div>Oct 18 14:55:50 Debian-60-squeeze-64-minimal
/usr/sbin/opensips[11050]: ERROR:tm:t_forward_nonack: sending
request failed</div>
<div><br>
</div>
<div>I think that OpenSIPS tries to forward the messages to all
contacts in the location table, one contact after the other.
Because some of them are not valid anymore the server is unable
to send the message. This means that it takes 30 seconds for an
INVITE to be received if there are 3 old contacts in the
location table, due to the 10 seconds timeout.</div>
<div><br>
</div>
<div>I have hoped that the following configuration would resolve
the problem. I thought it would make OpenSIPS to send the
message to the most recent contact first:</div>
<div><br>
</div>
<div>modparam("usrloc", "desc_time_order", 1)</div>
<div><br>
</div>
<div>It turned out that this is not the case, for whatever reason.</div>
<div><br>
</div>
<div>My questions:</div>
<div><br>
</div>
<div>1/ Is this behavior normal and expected? I.e. waiting 10
seconds for the TCP timeout before trying the next contact in
the location table?</div>
<div>2/ Is there a way to configure OpenSIPS to a) send the
messages in parallel to all contacts and b) to delete invalid
contacts from location table upon above error?</div>
<div>3/ Can I reduce the TCP timeout to something like 2 seconds?
If yes: how?</div>
<div><br>
</div>
<div>Thanks and best regards</div>
