Yes it can. In this particular case the function will assume that the domain

the
function will try to retrieve the domain name from that AVP and if it does not
exist (which is likely) then the function returns -1.
Some more examples:
lookup("$fd", "iptel.org") # lookup the iptel.org domain name
lookup("$fd", "(a)to.uri.host") # lookup the hostname part of To header
URI
# The following two are equivalent
lookup("$fd", "$abcd) # lookup the domain stored in
"abcd" AVP
lookup("$fd", "$fu.abcd) # lookup the domain stored in
"abcd" AVP
Jan.
So, the following example
lookup_domain("$fd", "(a)from.uri.host")ost");
you didn't answer, can the above be also written as:
lookup_domain("$fd", "$fd");
if not, why?
