<h2 class="title topictitle2" id="ariaid-title3">DTMF In-band Transport Method</h2>
<div class="body conbody"><p class="shortdesc">This is the most used transport method for DTMFs transmission. In this case, the DTMFs
and the voice are transmitted together in the RTP stream. </p>
<p class="p">This transport method is only reliable with G.711 or G.729 codecs. The DTMF In-band transport
method is configurable by endpoint, or the same method can be selected for all the endpoints of
the unit. In general, FXS, FXO, R2, and E&M endpoints are configured to use the In-band
transport method for DTMF transmission.</p>

<h2 class="title topictitle2" id="ariaid-title4">DTMF Out-of-Band Transport Method</h2>
<div class="body conbody"><p class="shortdesc">When using the Out-of-Band transport method, the DTMFs and the voice are transmitted in
two different streams where the voice is sent over RTP, but DTMF is sent either in RTP or SIP
depending on the chosen transport method (<span class="keyword wintitle">Out-of-Band using RTP</span> or <span class="keyword wintitle">Out-of-Band using SIP</span>. However, the Out-of-Band
transport method can only be used if the SIP peer supports the method, otherwise the DTMF
transport method falls back to In-band. </p>
<p class="p">Because some compression codecs such as G.723.1 and G.729 effectively distort voice because
they lose information from the incoming voice stream during the compression and decompression
phases. For normal speech this is insignificant and becomes unimportant. In the case of pure
tones (such as DTMF) this distortion means the receiver may no longer recognize the tones. The
solution is to send this information as a separate packet to the other endpoint, which then plays
the DTMF sequence back by regenerating the true tones. Such a mechanism is known as Out-of-Band
DTMF. The Mediatrix unit receives and sends Out-of-Band DTMFs as per ITU Q.24. DTMFs supported
are 0-9, A-D, *, #. </p>
<p class="p">The DTMF Out-of-Band (using either SIP or RTP) transport method is configurable by endpoint, or
can be selected for all the endpoints of the unit. ISDN endpoints are normally configured to use
an Out-of-Band transport method for DTMF transmission.</p>

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>
