asterisk users - Mar 2010 - DUNDILOOKUP doesn't return record

Hi All,

Found an issue with DUNDILOOKUP function in Asterisk 1.6.0.5.
I was using DUNDIQUERY (Set(ID=${DUNDIQUERY(${MNUM},priv,b)})) for
dundilookup and it was working fine.
But when I tried to use DUNDILOOKUP function
(Set(DL=${DUNDILOOKUP(${MNUM},priv,b)})), it didn't retuen me a
result. Moreover, the cli command 'dundi lookup 12345 at priv' returned
me the result at the same time!

I also checked that ${MNUM} is set properly.

What can be a problem?
Please guide me where I do a mistake.
