<h2 class="title topictitle2" id="ariaid-title2">SIP Penalty Box</h2>
<div class="body conbody"><p class="shortdesc">The penalty box feature is useful when a given host FQDN resolves to a non-responding
address. When the address times out, it is put into the penalty box for a given amount of time.
During that time, this address is considered as “non-responding” for all requests</p>
<p class="p">This feature is useful when DNS requests return multiple or varying addresses for a host FQDN.
It makes sure that, when a host is down, no SIP request is sent to it for a minimal amount of
time. When enabled, this feature takes effect immediately on the next call attempt. </p>
<div class="p">The penalty box feature is applied only when using UDP or TCP connections established with a
FQDN. A similar penalty box feature for the TLS persistent connections is available via the
<span class="keyword parmname">TLS Persistent Retry Interval</span> parameter.<div class="note note note_note"><span class="note__title">Note:</span> The Penalty Box feature works
only with Trunk Gateways, i.e. it is disabled when an Endpoint Gateway type is
configured.</div></div>

<h3 class="title topictitle3" id="ariaid-title3">SIP Penalty Box vs Transport Types</h3>
<div class="body conbody"><p class="shortdesc">Media5 recommends to use this feature with care when supporting multiple transports or
you may experience unwanted behaviours. When the Mediatrix unit must send a packet, it retrieves
the destination from the packet. If the destination address does not specify a transport to use
and does not have a DNS SRV entry that configures which transport to use, then the Mediatrix unit
tries all transports it supports, starting with UDP. If this fails, it tries with TCP. The unit
begins with UDP because all SIP implementations must support this transport, while the mandatory
support of TCP was only introduced in RFC 3261.</p>
<div class="note note note_note"><span class="note__title">Note:</span> It is not the destination itself that is placed in the penalty box, but rather targets,
which are a combination of address, port, and transport. Targets put in penalty box are not used
unless all the targets are in the penalty box. In that case, the highest priority target is used. </div>
<p class="p">Let’s say for instance that the Mediatrix unit supports both the UDP and TCP transports. It
tries to reach endpoint “B” for which the destination address does not specify a transport and
there is no DNS SRV entry to specify which transports to use in which order. It turns out that
this endpoint “B” is also down. In this case, the Mediatrix unit first tries to contact endpoint
“B” via UDP. After a timeout period, the UDP target is placed in the penalty box and the unit
then tries to contact endpoint “B” via TCP. This fails as well and the TCP target is also placed
in the penalty box.</p>
<p class="p">Now, let’s assume endpoint “B” comes back to life and the Mediatrix unit tries again to contact
it before UDP and TCP targets are released from the penalty box. First, the unit tries UDP, but
it is currently in the penalty box and there is another transport left to try. The Mediatrix unit
skips over UDP and tries the next target, which is TCP. Again, TCP is still in the penalty box,
but this time, it is the last target the Mediatrix unit can try, so penalty box or not, TCP is
used all the same to try to contact endpoint “B”.</p>
<p class="p">There is a problem if endpoint “B” only supports UDP (RFC 2543-based implementation). Endpoint
“B” is up, but the Mediatrix unit still cannot contact it: with UDP and TCP in the penalty box,
the unit only tries to contact endpoint “B” via its last choice, which is TCP.</p>
<p class="p">The same scenario would not have any problem if the penalty box feature was disabled. Another
option is to disable TCP in the Mediatrix unit, which makes UDP the only possible choice for the
unit and forces to use UDP even if it is in the penalty box.</p>
<p class="p">You must fully understand the above problem before configuring this feature. Mixing endpoints
that do not support the same set of transports with this feature enabled can lead to the above
problems, so it is suggested to either properly configure SRV records for the hosts that can be
reached or be sure that all hosts on the network support the same transport set before enabling
this feature.</p>

<p class="p"> It is up to the caller to decide what to do when it receives a 422 to its INVITE. The
Mediatrix unit will automatically retry the INVITE, with a Session-Expires value equal to the
minimum value that the user agent server was ready to accept (located in the Min-SE header). This
means that the maximum value as set in the Mediatrix unit might not be followed. This has the
advantage of establishing the call even if the two endpoints have conflicting values. The
Mediatrix unit will also keep retrying as long as it gets 422 answers with different Min-SE
values.</p>

supports session timers. In the case where the caller does not support session timers, the
Mediatrix unit assumes the role of the refresher.</p>

<div class="body conbody"><p class="shortdesc">Mediatrix devices are supplied with an exhaustive set of documentation. </p>
<p class="p">Mediatrix user documentation is available on the <a class="xref" href="http://documentation.media5corp.com" target="_blank">Media5 Documentation
Portal</a>.</p>
<div class="p">Several types of documents were created to clearly present the information you are looking for.
Our documentation includes:<ul class="ul" id="concept_v4k_q3h_1r__ul_bqy_cjh_1r">
<li class="li"><strong class="ph b">Release notes</strong>: Generated at each GA release, this document includes the known and
solved issues of the software. It also outlines the changes and the new features the release
includes.</li>
<li class="li"><strong class="ph b">Configuration notes</strong>: These documents are created to facilitate the configuration of a
specific use case. They address a configuration aspect we consider that most users will need to
perform. However, in some cases, a configuration note is created after receiving a question
from a customer. They provide standard step-by-step procedures detailing the values of the
parameters to use. They provide a means of validation and present some conceptual information.
The configuration notes are specifically created to guide the user through an aspect of the
configuration. </li>
<li class="li"><strong class="ph b">Technical bulletins</strong>: These documents are created to facilitate the configuration of a
specific technical action, such as performing a firmware upgrade.</li>
<li class="li"><strong class="ph b">Hardware installation guide</strong>: They provide the detailed procedure on how to safely and
adequately install the unit. It provides information on card installation, cable connections,
and how to access for the first time the Management interface.</li>
<li class="li"><strong class="ph b">User guide</strong>: The user guide explains how to customise to your needs the configuration
of the unit. Although this document is task oriented, it provides conceptual information to
help the user understand the purpose and impact of each task. The User Guide will provide
information such as where and how TR-069 can be configured in the Management Interface, how to
set firewalls, or how to use the CLI to configure parameters that are not available in the
Management Interface.</li>
<li class="li"><strong class="ph b">Reference guide</strong>: This exhaustive document has been created for advanced users. It
includes a description of all the parameters used by all the services of the Mediatrix units.
You will find, for example, scripts to configure a specific parameter, notification messages
sent by a service, or an action description used to create Rulesets. This document includes
reference information such as a dictionary, and it does not include any step-by-step
procedures. </li>
