•"This UA is the typical
'business-class' hard-phone. A number
of
• appearances are typically configured
statically and labeled on
• buttons, and calls may be managed using
these configured appearances.
• Any calls outside this range should be
ignored, and not mapped to a
• free button.
Users of these devices often select/seize specific
• appearance numbers for outgoing calls, and
the UA will need to
• select/seize the appearance number and wait
for confirmation from the
• Appearance Agent before proceeding with
calls.
•
• OPEN ISSUE: We currently have no upper
limit on the appearance
• number in the specification. Do we need a way for an Appearance
• Agent to indicate to a UA that no more
appearances are available?”

•Proposal: Do not specify this in the document
