this example GK1 doesn't know how to resolve 4953756. It asks GK2 to help. It
provides the sourceInfo of EP1 (e.g., an h323-ID or the phone number of the
originator). GK2 uses the h323-ID to "figure out" the country code and area code
that should be used for the Called party (if EP1 dials a local number, then it
is the same country code as EP1's).</FONT></SPAN></DIV>

course GK1 can do whatever it pleases since it might be using LRQs for its own

<DIV><FONT face=Arial size=2>Francois,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I agree with you that what we should do is
modify the text to be a bit more tolerant of what "source" means. It
might be the source Gatekeeper or it might be the source endpoint's
alias. It is possible to find either there today (since either an
endpoint or a Gatekeeper may source an LRQ), so the text should reflect
that.</FONT></DIV>

all,</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=110593618-13062001>The sourceInfor
in LRQ states that it should be the alias address of the originator of the
LRQ (as opposed to the originator of the call).</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=110593618-13062001></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=110593618-13062001>One of the
consequence of this is that if an endpoint sends an ARQ to its gatekeeper,
and its gatekeeper can not resolve it, the LRQ that it will send to other
gatekeepers may not have enough information to resolve the address. For
example, if the number was a "local" number or a "national" number, the
gatekeeper that receives the LRQ will not have enough context (where is the
originator of the call) to resolve the address (like the country code of the
calling user to figure out the contry code of the called
user).</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=110593618-13062001></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=110593618-13062001>Anybody has any
views on this?</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=110593618-13062001></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=110593618-13062001>My take is that
the LRQ.sourceInfo should really reflect the alias address of the originator
of the call (the initial ARQ) as opposed to the gatekeeper that originated
the LRQ. An alternative would be to define a new field, but I'm not too keen
on this approach since it won't work until H.323v5...</SPAN></FONT></DIV>
