Thanks for the tip. Elsewhere, someone suggested adding this code in
extensions.conf, which solved the problem:

===============
[macro-dialsipuri]
exten => s,1,Set(dialuri=${CUT(ARG1,\;,1)})
exten => s,n,Verbose(Calling SIP URI ${dailuri})
exten => s,n,Verbose(--- From: ${CALLERID(all)})
exten => s,n,Dial(SIP/${dialuri},60,tr)
exten => s,n,Congestion()

[internal]
...
exten => _[a-z].,1,Macro(dialsipuri,${EXTEN}@${SIPDOMAIN})
exten => _[A-Z].,1,Macro(dialsipuri,${EXTEN}@${SIPDOMAIN})
===============

I'll read up on Freenum, but I was just trying to do something that I
thought was very simple, namely make a phone call over the Net, ie.
have XLite send an INVITE to Asterisk, which would then forward the
INVITE to the remote server, which would ring the phone. I expected
Asterisk users to make direct calls routinely, but maybe it's not that
frequent.

Thanks Leif. I was going through the 2nd edition, which doesn't seem
to deal with direct, Internet dialing. I'll go through that Chapter 12
in the 3rd edition.

Thank you.
