Thanks Daniel. I added that line above, told Asterisk to reload the
dialplan, and typed the following in XLite:

9*031600 at ekiga.net

This is to perform an echo test

I guess something else must be done to Asterisk for this to work:

==========
CLI>
    -- Executing [9*031600 at my-phones:1] Dial("SIP/6011-00a1b67c",
"SIP/*031600") in new stack

[Dec 17 11:43:14] WARNING[306]: chan_sip.c:2923 create_addr: No such
host: *031600

[Dec 17 11:43:14] WARNING[306]: app_dial.c:1183 dial_exec_full: Unable
to create channel of type 'SIP' (cause 3 - No route to destination)
  == Everyone is busy/congested at this time (1:0/0/1)
  == Auto fallthrough, channel 'SIP/6011-00a1b67c' status is
'CHANUNAVAIL'
==========

I also tried this, same result:

exten=>_9.,1,Dial(SIP/ippi_outgoing/${EXTEN:1})

Do I need to add something in sip.conf, or some other configuration
file?

Thank you.
