Product Overview
MGCP is a client/server protocol. The CA handles all aspects of setting up calls to and from endpoints.
CAs or control servers provide the feature capabilities that a particular endpoint can use. Endpoints
connected to different CAs likely have a different set of features that they can use. Because all
call-control features are in the control server, each control server vendor decides which features are most
important, and therefore different control server vendors differ in essential features.
BTXML Support
The Cisco MGCP IP phone supports Basic Telephony eXtensible Markup Language. BTXML defines
XML elements for controlling the user interface of an IP telephone. It describes what information is
displayed on the screen and how to provide input using soft keys and hard keys.
For information about creating and using BTXML scripts on the phone, refer to the Cisco IP Phone
MGCP BTXML Version 2.0 Application Development Guide.
Cisco CallManager XML Support
The Cisco MGCP IP phone supports Cisco CallManager XML cards that you configure to provide data
such as stock quotes, calendars, and directory lookups. Phone users access this information using phone
buttons such as the Services or Directories buttons or soft keys. See
IP Phones,"
The phone supports Cisco CallManager XML up through version 3.0. It does not support the following
XML objects in version 3.1 and later: CiscoIPPhoneIconMenu, CiscoIPPhoneExecute,
