Juha,
i have always thought that AVPs exits per transaction.
that does not
seem to be the case, however, because when i put in the beginning of my
script
xlog("L_INFO", "Caller lcr_id $avp(CALLER_LCR_ID_AVP)\n");
this gets printed to syslog:
Aug 29 11:34:34 localhost /usr/sbin/sip-router[10210]: INFO: Caller lcr_id 2
is this the indented behavior? do i really need to delete all AVPs in
the beginning of the script in order to make sure that they don't have
any values left from processing of previous message?
What kind of AVP is this? Where is its value defined? If it is a
global AVP (defined in global_attrs table) then what you see could be
correct. Global AVPs are always present.
If this is a domain level avp (defined in domain_attrs table) then
what you see could be correct, provided that you called some function
from domain module before the statement above (i.e. lookup_domain).
If it is neither domain-level nor global avp then the behavior you see
is not intended.
You can also try to use the ser version of xlog module to see where
the value comes from:
xlog("L_INFO", "User-level value: %$fu.CALLER_LCR_ID_AVP\n");
xlog("L_INFO", "Domain-level value: %$fd.CALLER_LCR_ID_AVP\n");
xlog("L_INFO", "Global-level value: %g.CALLER_LCR_ID_AVP\n");
Provided that this is an AVP with string name (If I am not mistaken
then the ser version of xlog module does not support AVPs with integer
names).
