+<p>MMS Settings provides a generic way to store settings for Multimedia Message
+Service (MMS) messaging. </p>
+<p>Multimedia Messaging Service (MMS) is a standard for telephone messaging
+systems for sending messages that include multimedia objects (images, audio,
+video, rich text). </p>
+<section><title>Purpose</title> <p>Settings functionality is provided by the <filepath>mmsgenericsettings.dll</filepath> file
+to allow a messaging client to persist MMS settings in the Central Repository.
+The settings functionality is also used by the Server MTM to retrieve the
+setting information before sending and receiving messages. </p> </section>

+provides message settings encapsulation classes to manage MMS settings. The
+MMS settings are stored in the central repository and MMS are stored in the
+Message Store. </p> <p>The following settings are supported by <filepath>mmsgenericsettings.dll</filepath> to
+manage MMS settings: </p> <ul>
+<li id="GUID-A505F5BF-6604-520F-9B22-63404BD04F2D"><p>MMSC (MMS server) address </p> </li>
+<li id="GUID-6F7A3C4D-36BD-5AD6-A892-0713D95D18AB"><p>WSP or HTTP transport
+(the HTTP or WSP transport can be selected at the run-time). </p> </li>
+<li id="GUID-6515A2F5-9DE3-58D3-B64C-F2424ACD90FF"><p>Automatically get messages
+on notification </p> </li>
+<li id="GUID-22EDBCFF-861F-5C59-9143-575F23DDB79B"><p>Request delivery reports </p> </li>
+<li id="GUID-C62BC75D-DAE8-51E9-8097-24D2A76DF513"><p>Preferred IAP for the
+MMS network connection </p> <p>If connection fails with the preferred IAP
+or WAP account, a connection using the second choice option, if present, is
+made. The transport selection (WSP or HTTP) determines whether the WAP or
+HTTP account preferences are applied. </p> </li>
+</ul> </section>
+<section><title>API summary</title> <p>The following APIs are used for MMS
+settings: </p> <ul>
+<li id="GUID-A83F08BF-9443-5264-BFA7-94B0CB3511BD"><p>The <xref href="GUID-45F828BF-DC03-3C82-89B5-010687BDE91D.dita"><apiname>CMmsAccounts</apiname></xref> class
+is used to store and restore the configuration settings. </p> </li>
+<li id="GUID-5D775323-165D-539F-AF3A-9E6458C60E90"><p>The <xref href="GUID-1E1BA9E3-52E1-3AE6-BC62-3EBDA577107F.dita"><apiname>CMmsSettings</apiname></xref> class
+is used to specify and retrieve configuration settings. Messaging clients
+must use an instance of this class along with the <xref href="GUID-45F828BF-DC03-3C82-89B5-010687BDE91D.dita"><apiname>CMmsAccounts</apiname></xref> class
+to store and restore the configuration settings. </p> </li>
+<li id="GUID-8D4045E2-B720-5E15-A929-750054FB5226"><p>The <xref href="GUID-C79B080E-8BE7-3126-93B9-BA59B90C2200.dita"><apiname>MMmsSettingsObserver</apiname></xref> class
+is used to provide the interface for notification of changes that occur in
+the Central Repository. </p> </li>
+</ul> <p><b> Message encapsulation </b> </p> <p>The classes above provide
+message access functionality which is used to create, store, restore and read
+messages. The following are the functions of the message classes: </p> <ul>
+<li id="GUID-A3DF991D-2A3E-5B39-ACBF-EC9F8F651CC1"><p>Adding media objects
+to the message. </p> </li>
+<li id="GUID-AA60377A-0656-56F3-9962-468DD6ED6CB1"><p>Enumerating through
+media objects. </p> </li>
+<li id="GUID-8C5AB526-139C-5F07-90E1-CBC40DB962D8"><p>Adding recipients and
+a subject line to a message. </p> </li>
+<li id="GUID-07D074D7-A3E4-59EF-9BAD-E7B1FB47435B"><p>Adding other headers
+to the message. For example, expiry date. </p> </li>
+<li id="GUID-9365FAB8-5F61-510D-9FBA-3CB14B06E5DD"><p>Finding the appropriate
+media object for a given Uniform Resource Identifier (URI) in the Synchronized
+Multimedia Integration Language (SMIL). </p> </li>
+</ul> <p>The message data is stored in the central repository using one entry
+per message regardless of the number of media objects added to the message.
+This is preferable to using multiple message entries as it is faster and uses
+less disk space. </p> </section>
