During text entry, the phones display softkeys to assist users with text entry. Users can navigate between fields with the vertical scroll button that is used to navigate menus. The InputItem tag defines each item in the list. The number of InputItems must not exceed five. Each input item includes a DisplayName, which is the prompt that is written to the display for that particular item.
Each item also has a QueryStringParam, which is the name of the parameter that is appended to the URL when it is sent out after input is complete. Each input item can also use the DefaultValue tag to set the default value to be displayed. The final attribute for each input item comprises a set of InputFlags.
The following table describes the input types that are currently defined. N Numeric Enter numbers as the only acceptable input. E Equation Enter numbers and special math symbols. U Uppercase Enter uppercase letters as the only acceptable input. L Lowercase Enter lowercase letters as the only acceptable input. P Password field Enter individual characters using the standard keypad-repeat entry mode.
The system automatically converts accepted characters into an asterisk, keeping the entered value private. The softkeys include the Edit Dial softkey, which allows users to insert access codes or other necessary items before dialing. To create a custom directory, use the following optional objects in the order in which they are listed: 1 Use the CiscoIPPhoneInput XML object to collect search criteria. CiscoIPPhoneImage The CiscoIPPhoneImage provides a bitmap display with a x 65 pixel pane irrespective of the window mode being normal width or wide width , that is available to access services.
Each pixel includes four grayscale settings. A value of three 3 displays as black, and a value of zero 0 displays as white. Note The phone uses an LCD display, which inverts the palette. This attribute is supported on the Cisco Unified IP Phones , , , , , , , , and The WindowMode attribute accepts either of the following values: Normal: Default value The application window is in the normal-width mode.
See the following figure. Wide: The application window is in the full-width mode, that is the window expands to the complete phone screen width. The wide mode supports a maximum width of pixels for an image. If the attribute name is wrong, the name is ignored and the default window width is used. If the attribute value is wrong, the parser reports an XML parse error and the object is rejected.
The WindowMode attribute is ignored on phones that does not support this feature. In these cases, the window remains the original width. In phones that support this attribute, the absence of the attribute means that the phone uses Normal mode. The Title displays at the top of the page, and the Prompt displays at the bottom.
Use LocationX and LocationY to position the graphic on the phone display. Position the upper, left corner of the graphic at the pixel defined by these two parameters. Setting the X and Y location values to 0, 0 positions the graphic at the upper, left corner of the display.
Setting the X and Y location values to -1, -1 centers the graphic in the services pane of the phone display. Use Width and Height to size the graphic. If the values do not match with the pixel stream specified in the Data field, results will be unpredictable or incorrect. Depth specifies the number of bits per pixel. IP phones support a maximum value of 2 bits per pixel. A bit depth of 1 is black and white. The Data tag delimits a string of hexadecimal digits that contain the packed value of the pixels in the display.
In the IP phone, each pixel has only four possible values, which means that you can pack four pixels into a single byte. A pair of hexadecimal digits represents each byte. The following figure provides an example of the mechanics of pixel packing. Scanning from left to right in the display, the illustration shows the process for packing consecutive pixel values of 1, 3, 2, and 0.
Then, the binary pairs get reordered in sets of four to create a single reordered byte, which the two hexadecimal digits represent. If the number of pixels to be displayed does not represent an even multiple of four, pad the end of the pixel data with blank zero value pixels, so the data is packed correctly. The phone ignores the padded data. Note Before displaying a graphic image on an IP phone, the software clears the pane dedicated to services.
If a service has text or other information that must be preserved including the title area , the information must get redrawn as part of the graphic. If the title is to be hidden, the graphic must be large enough to cover it. The Cisco Unified IP Phone G, for example, has a display area of x pixels available to the Services pane and renders images in bit color. The PNG image can be either palettized or RGB, and the maximum image size and color depth are model dependent see the following table.
If the number of colors in the image is not reduced to match the phone capabilities, the image will be dithered by the phone and yield less than desirable results in most cases. To reduce the number of colors in a graphics editing program, such as Adobe Photoshop, use the Posterize command. The Posterize command takes one value as input for the number of color tones per color channel. Use graphic menus in situations when the items may not be easy to display in a text list.
Menu items in the graphic menu have a name, like the text menu counterparts. Although the name does not display to the user, it still performs a function. The name of the menu item provides the default title that is used when the URL for the chosen item loads.
If the loaded page has a title of its own, the phone uses the defined title instead. When one of those objects is selected, a URL action initiates. However, the FileMenu does not use the keypad, but uses rectangular touch areas. This allows a sense of Z-order for images where smaller touchable objects can be overlaid on top of larger ones. Use icon menus in situations when you want to provide additional visual information to the user to show the state or category of an item. For example, you include a read and unread icon in a mail viewer.
You can use the icons can to convey the message state. The following figure shows an IconMenu on an IP phone. For example, you can use icons to indicate priority see the following figure. If the validation is successful, the phone uses the icon specified by the Resource URI. The root cause for any parsing errors displays in the phone console logs.
The Status object cannot be closed or cleared by the user for example, by pressing Services because the Status object is only present on the Call plane. This would typically occur as the result of an application server pushing an Execute object to the phone that contains the Init:AppStatus URI. It is not necessary to clear an existing Status object before sending a new Status object.
The new object simply replaces the old object. Dynamic Application Status Window Size You can enable applications to dynamically adjust their window sizes based on the displayed content. The minimum size requirements limit the windows size so that it is large enough to stand out from the Overview content. For example, using a smaller window for an application allows more content from the Overview to be displayed.
To allow dynamic sizing, do not configure the Text and Timer areas with any value other than the default used by the XML parser. See the following table for an overview of the maximum and minimum image area sizes by phone model.
Most phone models support all sizes between the minimum and maximum. For these phones, you should implement both the maximum size and minimum size windows, ignoring all of the intermediate sizes. It is not a displayable object for providing user interaction. The purpose of this object is to deliver potentially multiple execution requests to the phone.
Order of execution is not guaranteed, so ExecuteItems will likely not execute in the order in which they are listed in the CiscoIPPhoneExecute object. The Priority attribute is used to inform the phone of the urgency of the execute request and to indicate whether the phone should be interrupted to perform the request.
The Priority levels determine whether the phone must be idle to perform the requested action. The following table lists the Priority levels and their behavior. Internal URIs always execute immediately. As a result, a ResponseItem exists for each ExecuteItems that you send.
The order differs based on completion time, and the execution order is not guaranteed. The Data attribute contains any special data for the item. The Status attribute specifies a status code. Zero indicates that no error occurred during processing of the ExecuteItem. The SoftkeyItem can define separate actions to be taken when the softkey is pressed and released.
If not, the Update softkey is assigned. Do not include any tags other than those defined in your XML display definitions. The following table lists characters and their escape values. If the XML encoding header is not specified, the phone will default to the encoding specified by the current user locale.
The unsupported objects are not contained in a standard application context and are handled differently by the Application Manager API. An application can only be minimized in a program by a call to App:Minimize, but this invocation could occur by direct action of the user for example, from a softkey invocation or from the application using a push request.
This API extends capabilities beyond the legacy RTP streaming URIs by providing support for stream start and stop event listeners and the ability to specify other extended stream attributes, such as codec type. The notes mentioned in the tables follow the final table. The system initiates the event as if the button was physically pressed. Note that when buttons are pressed with this method, if the button is not present on the phone hard button or not available softkey when the URI is processed, the event is discarded.
If the softkey set is changing and disabled while the event is being processed, the request is discarded. The following tables list the Key URIs and the phone models in which these softkeys are supported. The Cisco IP Phone and supports lines, 5 sessions, and features. It does not have feature buttons. If there is no application open, then the request has no effect. Additionally, the Exit softkey takes the application to the previous screen, and if the application is at the top level, the Exit softkey closes the application.
Help is provided within the context of each application. You can use Key:Contacts to invoke the new contacts application in these phones. Using the Display URI, you can control how long the backlight remains on or off. Note, however, that other administrator-controlled or user-indicated display settings take precedence over the Display URI. Therefore, various phone states such as phone startup, incoming and active calls, or other user input states override the Display URI settings.
Value must be an integer ranging from minutes. If the value is set to 0, the display remains in the indicated state indefinitely unless activated by automated or user input. Examples Display:Off turns the phone display off for 1 hour 60 minutes. Display:On turns the phone display on for 10 minutes. Display:Off:0 turns off the display off until activated.
Display:Default returns the display to its specified state for that time. The SoftKey URI allows developers to customize softkey names and layout in the Services and Directories windows while retaining the functionality that the softkeys provide. The URI invokes the native functionality that each key possesses in the given object context. Moving from left to right, the Exit is the first softkey followed by the Submit, Select, Update, or Next softkey, and finally the Delete softkey.
When the user performs an action with a softkey, you can either append a query string parameter to the URL of the highlighted MenuItem or append the query string parameter from the MenuItem to the URL of the softkey. If the user chooses the MenuItems with the numeric keypad, the cursor moves to that entry, but nothing executes because the values are QueryStringParam URIs.
If the user presses either custom softkey, the currently highlighted MenuItem URI value gets appended to the softkey URL that was pressed and requested from the web server. Choose the best way to perform the action based on your applications needs.
The Item selection example has a slight advantage in that if the user chooses an item with the numeric keypad, the URL gets called. This action would allow you to invoke some default behavior, such as to read the message in the example. If a call is in a Held state connected but not actively streaming , the Tx or MTx URI request is accepted, but will terminate if the call resumes.
Thus, if the Rx or MRx stream is not terminated automatically, it would continue to play. For example, a user is listening to Internet radio feed and gets an incoming call. The user answers the call, which either closes or minimizes the Internet radio XSI application. Otherwise, the user has no intuitive way to stop the music stream. If the Rx or MRx URI request was done using push, then the associated application is responsible for using push Priority attributes and for stopping and starting the stream.
If the user initiates the Rx or MRx URI using an application, then the user likely is not concerned about having the audio mixed with the current call. However, the user should also be presented with an option to stop the application, when needed. This response provides visibility to the application if the phone is currently busy. It then allows the application to decide whether or not to terminate the existing stream and start a new one, rather than being controlled by the phone firmware.
Ensure that this is an even port number within the decimal range of to If no port is specified, the phone chooses a port and returns it when initiated by a push request. The supplied value is a percentage of the maximum volume level of the device and must be in the range The phone converts the specified percentage into the closest device-supported volume level setting and uses it. After the initial volume level gets set and the stream starts, you can manually change the volume level as needed.
If the optional volume parameter does not get included, the current volume setting on the phone gets used as the default. This same mechanism also plays ring files, and the format of the files is the same. If the phone is equipped with an message waiting light, the light will flash while the audio file is playing, providing a visual alert as well. To create PCM files for custom phone rings, you can use any standard audio editing packages that support these file format requirements.
Note In releases prior to 1. If the Vibrate parameters are not specified or if the device is unable to support custom Vibrate sequences, the device executes the default vibrate sequence. Value must be an integer ranging from milliseconds ms. Value must be an integer ranging from ms. Vibrate initiates five vibrations, each lasting for ms, followed by ms of silence. Device The Device URI instructs the device to automatically unlock the input or display interface without the user unlocking the device manually.
If the device is configured to automatically lock the input or display interface, the normal idle timeout behavior applies and the device is automatically locked again. The Dial URI invokes when it is contained in a menu item, the menu item is highlighted, and the device is taken off hook.
Commas represent 1 second pauses. The appId must be specified or this parameter will have no effect: it will always be false. Audible feedback to the user can be enabled or disabled and an optional application ID can be specified to ensure that the DTMF digits will only be sent to the call which is associated with a specific application. The comma represents a one second pause. Values can be 0 false or 1 true. Value must be and cannot contain colons.
The default value is null indicating that the active call should receive the DTMF digits, regardless of any application association. Example Make a call using a calling card service that implements these steps: 1 Connects to a calling card service using the Dial URI.
If Services is not currently open, it has no effect. If Messages is not currently open, it has no effect. If Directories is not currently open, it has no effect. For example, you can call the Notify URI from a softkey or menu item to trigger a back-end event that does not require an interface change, such as manipulating the state of audio streams or other non-visual resources.
Thus, the back-end application cannot rely on HTTP cookies or session information to uniquely identify the client or application. Instead, the application must embed any necessary information in the Notify path and data fields, or leave the data field empty and rely on any default information provided by the specific event handler.
Value must be entered as a hostname or IP address. Value must be a number from Value cannot contain colons or semicolons. For HTTP, this is a baseencoded version of userid:password. Value cannot contain colors or semicolons. If the credentials parameter is not specified or if it is null, no Authorization header will be included in the request.
The HTTP notification service will retry the request 3 times before failing and logging an error message. Value cannot contain semicolons. Applications can request to change focus, to be minimized, or to be closed. When an Application URI request is made, it has a specific application associated with it not just the application context and that action can only be taken on that specific application.
The application specified in the appId parameter of the displayable XML object must be active at the time the action is requested, or an error will be returned. This also means that if an application closes or becomes non-active for example, if user navigates out of an application, or a new application is pushed to the context any pending Application URI requests are immediately cancelled. This is a request, not a demand, as higher priority applications may prevent the application from actually gaining focus.
Applications must use onAppFocusGained event handlers to know when focus is actually gained. Applications must use onAppFocusLost event handlers to know when focus is actually lost. This request always results in the application eventually being minimized. This request will result in the application context and all applications within that context being closed. Values must range from seconds ; default is 60 seconds. Any pending timers are automatically cancelled when the displayable object changes for an application context.
Values must range in length from string characters and cannot contain colons. The default value is the application of the displayable object in which the URI is defined. Note If the Application URI is used in an ExecuteItem, you must specify the applicationId because the application context of the request cannot be inferred.
The application is notified of the actual state change asynchronously using the event handlers. This chapter describes the capabilities of the HTTP interface. The provided credentials must be of a user in the global directory with a device association with the target phone.
To push large objects to the phone, the server application must take an indirect approach, by pushing an Execute object to the phone that contains an ExecuteItem that points to the URL of the large object. The phone does not cache content. This setting comprises two parameters: a time in seconds and a URL. These two parameters direct the recipient to wait the time given in the seconds parameter and then get the data to which the URL points.
It means that a new page can replace any XML object that displays after a fixed time. The following figure shows an example of how to use the refresh setting. This sample page shows the user the current value of Cisco stock. The display repeatedly cycles between the final two views. Figure Refresh Display Sample Refreshing the display can occur without user intervention, because the display automatically cycles if a timer parameter is specified.
On any given screen, however, the user can force an immediate reload by pressing the Update softkey. Also, if a timer parameter of 0 was sent in the header, the page never automatically reloads. In this case, the display will move to the next page only when the Update softkey is pressed. If no refresh URL is specified, the current page gets reloaded. CM-Sim significantly lowers the requirements for service development.
