Cisco TelePresence SX80 API Reference Guide
Feedback from codec over HTTP
To get notifications from the codec, you need to register HTTP
feedback expressions. The codec will then use HTTP POST
to send feedback messages to the supplied IP-address. This
means that you have to have a HTTP server running for your
application to receive updates from the codec.
Registering for feedback
The command for registering is
xCommand HttpFeedback Register. The syntax for this
command and its arguments are described in this section.
HttpFeedback Register syntax:
xCommand HttpFeedback Register
FeedbackSlot: <1..4>
ServerUrl(r): <S: 1, 2048>
Expression: <S: 1, 255>

HttpFeedback Register arguments:
FeedbackSlot: The codec can register up to 4 slots of servers
requesting HTTP feedback. Set the registering to one of them.
Note: Avoid using FeedbackSlot 3 in an environment where
Cisco TelePresence Management Suite (TMS) is used as TMS
uses this feedbackslot to register its expressions.
ServerUrl: The URL that you want the codec to post the HTTP
feedback messages to.
Expression 1-15: Register the expressions you want to
receive feedback on. See the ”Feedback mechanism” on
page 19 section for more information about the expression
formats.
Example: Registering feedback on configuration changes,
disconnect events and call status changes.
<Command>
<HttpFeedback>
<Register command=”True”>
<FeedbackSlot>1</FeedbackSlot>
<Ser verUrl>http://127.0.0.1/
myhttppostscripturl</ServerUrl>
<Expression item=”1”>/Configuration</
Expression>
<Expression item=”2”>/Event/
CallDisconnect</Expression>
<Expression item=”3”>/Status/Call</
Expression>
</Register>
</HttpFeedback>
</Command>
Feedback output
When the codec notifies the registered HTTP server about
changes, the body contains the same XML as when polling.
There is however one small difference. The root-node
contains an Identification node with children that specify the
codec from which the notification originated. This means that
you can handle multiple codecs with a single HTTP server URI.
Example: Audio volume changed.
<Configuration xmlns=”http://www.company.com/XML/
CUIL/2.0”>
<Identification>
