I did some more test with other scenarios:
I did a case with simulates voicemail behavior. test procedure was the following
(*when calling directly to the destination which played the role of voice mail there was
no problem with the session establishment)
first go through ser for first invite
dump_attrs()
lookup_user("$t.did","@ruri")
dump_attrs()
load_attrs("$tu","@ruri")
load_attrs("$tr","@ruri")
dump_attrs()
lookup_contacts("location")
before lookup_contacts dump_attrs() gives:

Feb 13 16:08:50 rd ser[10548]:
AVP["forward_voicemail"]="sip:evn@voip.touk.pl"
then because the user wasn't found in the database I replace the Request uri
by forward_voicemail avp and do t_relay().
After this the modified invite is sent to ser again and there is a second go (with
completely the same procedure logic)
before lookup_contacts("location") dump_attrs() gave:
Feb 13 16:30:31 rd ser[10550]: INFO: avp.c:540: class=GLOBAL

Feb 13 16:30:31 rd ser[10550]: AVP["uri_avp_test"]="uri_avp_test"
and here was an error because in this case lookup_contacts("location") returned
negative response although the user pointed by $tr.uid avp was in the database!
In the case of direct call to evn(a)voip.touk.pl there is no error and the dump_attrs()
returns the same result before the lookup_contacts() was invoked there was only track to
set in the uri class!
I hope this can figure out what is going on.

I did some tests.
I sent them on the list because I wat not sure how to interpret their correctness beefore
putting them on the tracker
I did the following general procedure:
dump_attrs()
lookup_user(..)
dump_attrs()
load_attrs(..)
dump_attrs()
lookup_contacts(..)
Case one:
dump_attrs()
lookup_user("$t.uid","@ruri")
dump_attrs()
load_attrs("$tu","$t.uid")
dump_attrs()
lookup_contacts("location")
my observations: after lookup_user("$t.uid","@ruri") uid avp appered
in the uri class and to track, lookup_contacts("location") found the user
