<DIV><FONT face=Arial>So, I'm still confused. "are supported"
means:</FONT></DIV>
<DIV><FONT face=Arial> a) The device may ONLY send that subset of
characters?</FONT></DIV>
<DIV><FONT face=Arial> b) The device must support that subset, but
may send others?</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Also, any insight into what the
"userInputSupportedIndication" element is for within
"UserInputIndication"?</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Thanks,</FONT></DIV>

<DIV><BR></DIV>Hi Paul,<BR><BR>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><BR>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><BR>--Dave<BR><BR>At 11:40 AM

face=arial>Folks,<BR></FONT> <BR><FONT face=arial>I have a question
regarding H.245 User Input Indication. In section B.14.6, it
states:<BR></FONT> <BR><FONT face=arial> </FONT><FONT
face=arial color=#0000ff>"The boolean basicString,<B> </B>when true,
indicates that the characters 0-9, * and # are supported."</FONT>
</BLOCKQUOTE><BR>
<BLOCKQUOTE class=cite cite="" type="cite"><BR><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".<BR></FONT> <BR><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.<BR></FONT> <BR><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.<BR></FONT> <BR><FONT face=arial>Any clarification you can
provide would be most appreciated.<BR></FONT> <BR><FONT
