<DD>Hi Paul,<BR>
<DD>My recollection is that "are supported" was meant to indicate that
the device can send those characters. (I think UII can send
anything in the ASCII, and perhaps the Unicode, set.)<BR>
<DD>The purpose of the "are supported" bit is to allow an automatic menu
generator to limit the kinds of input it requests to what the far-end
terminal can actually send. (weak example: "Press # for Customer
Service" vs "Type SERVICE for Customer Service")...in fact people have
used UII to do things like text chat, which is difficult with only a
phone keypad.<BR>

<DD><FONT face=arial>Folks,</FONT>

<DD><FONT face=arial>I have a question regarding H.245 User Input
Indication. In section B.14.6, it states:</FONT>
<DD>
<DD><FONT face=arial> </FONT><FONT face=arial
color=#0000ff>"The boolean basicString, when true, indicates that the
characters 0-9, * and # are supported."</FONT> </DD></BLOCKQUOTE>
<BLOCKQUOTE class=cite cite="" type="cite">
<DD><FONT face=arial>My question is whether that those characters are
supported means that it is the only valid characters that may be
transmitted? Or is it also valid to transmit A,B,C,D, for
example? In other words, does this wording simply indicate the
minimum set of characters that must be supported or is the wording
intended to specify the complete set of characters that may be used
with "basicString".</FONT>
<DD>
<DD><FONT face=arial>H.323 Section 6.2.8 simply says that
"alphaNumeric" must be supported and that the characters 0-9, * and #
must be supported and others are optional. However, it does not
speak to whether endpoints must advertise support for basicString,
IA5String, etc.</FONT>
<DD>
<DD><FONT face=arial>A second question: can somebody explain why there
is a CHOICE of "userInputSupportIndication" inside the
UserInputIndication message? Would we not always advertise
capabilities via the UserInputCapability only? Is the intent of
having the "userInputSupportIndication" for changing capabilities
outside of a normal capability exchange.</FONT>
<DD>
<DD><FONT face=arial>Any clarification you can provide would be most
appreciated.</FONT>
