XML Softkey for Special Characters

(User Input Screens for 55i, 57i, and 57i CT only)

In Release 2.1, the IP Phone can dynamically receive a Symbol List when it receives the AastraIPPhoneInputScreen XML object. You can have a single symbol specified for the softkey, or you can have a list of symbols. When there is only one symbol in the list, the symbol displays with no delay. When there is a list of symbols, you can keep pressing the symbol softkey to cycle through the list of symbols to select the one you want to use.

To display a list of customized symbols to the phone’s softkey, the server must include the list of characters in the URI field of the XML softkey script. The URI must be in the format:

SymbolList=”<Symbol List content>”

The content of the Symbol List must be encapsulated by quotes. You can specify multiple symbols in one URI. For example, the SymbolList="@#” specifies the @ and # symbols.

Note: You can have multiple Symbol List softkeys with different lists of symbols. The maximum length of the data in a Symbol List is 230 characters.

There are some special characters that needed to be encoded due to XML limitations. The following table specifies these characters.

Symbol	XML Encoding
single quote (‘)	'
double quote (“)	"
greater-than sign (>)	>
less-than sign (<)	<
ampersand (&)	&

The following is an example XML URI using the characters in the table above:

SymbolList="@#&><"

The Symbol List content for this URI is @, #, &, >, <.
