<synopsis>Section for defining custom feature invocations during a call</synopsis>
<description>
<para>The applicationmap is an area where new custom features can be created. Items
defined in the applicationmap are not automatically accessible to bridged parties. Access
to the individual items is controled using the <replaceable>DYNAMIC_FEATURES</replaceable> channel variable.
The <replaceable>DYNAMIC_FEATURES</replaceable> is a <literal>#</literal> separated list of
either applicationmap item names or featuregroup names.</para>
</description>
<configOption name="">
<synopsis>A custom feature to invoke during a bridged call</synopsis>
<description>
<para>Each item listed here is a comma-separated list of parameters that determine
how a feature may be invoked during a call</para>
<para> Example:</para>
<para> eggs = *5,self,Playback(hello-world),default</para>
<para>This would create a feature called <literal>eggs</literal> that could be invoked
during a call by pressing the <literal>*5</literal>. The party that presses the DTMF
sequence would then trigger the <literal>Playback</literal> application to play the
<literal>hello-world</literal> file. The application invocation would happen on the
party that pressed the DTMF sequence since <literal>self</literal> is specified. The
other parties in the bridge would hear the <literal>default</literal> music on hold
class during the playback.</para>
<para>In addition to the syntax outlined in this documentation, a backwards-compatible alternative
is also allowed. The following applicationmap lines are functionally identical:</para>
<para> eggs = *5,self,Playback(hello-world),default</para>
<para> eggs = *5,self,Playback,hello-world,default</para>
<para> eggs = *5,self,Playback,"hello-world",default</para>

<synopsis>Groupings of items from the applicationmap</synopsis>
<description>
<para>Feature groups allow for multiple applicationmap items to be
grouped together. Like with individual applicationmap items, feature groups
can be part of the <replaceable>DYNAMIC_FEATURES</replaceable> channel variable.
In addition to creating groupings, the feature group section allows for the
DTMF sequence used to invoke an applicationmap item to be overridden with
a different sequence.</para>

<description>
<para>Each item here must be a name of an item in the applicationmap. The
argument may either be a new DTMF sequence to use for the item or it
may be left blank in order to use the DTMF sequence specified in the
applicationmap. For example:</para>
<para> eggs => *1</para>
<para> bacon =></para>
<para>would result in the applicationmap items <literal>eggs</literal> and
<literal>bacon</literal> being in the featuregroup. The former would have its
default DTMF trigger overridden with <literal>*1</literal> and the latter would
have the DTMF value specified in the applicationmap.</para>
