[Users] P-Asserted-Identity

[Ty Manthey]

Thanks Klaus, you pointed me in the right direction, I dropped my p_assert
table and used the subscriber table instead. If you guys wouldn't mind
looking this over for me when you get a chance, I would appreciate it. It
seems to be working just fine, but I wouldn't mind a second opinion if there
is a better way to do something. Here is what I ended up with:

# ------------- avpops params --------------------

# define "from_hdr" as an alias to AVP ID 12
# 
modparam("avpops", "avp_aliases", "from_hdr=s:12")
modparam("avpops", "avp_table", "avptable")
modparam("avpops", "uuid_column", "contact")
modparam("avpops", "username_column", "username")
modparam("avpops", "domain_column", "domain")
modparam("avpops", "db_scheme",
"scheme0:table=subcriber;uuid_col=uuid;username_col=username;value_type=stri
ng")

I moved this up to the "if method=register" section after my www challenge:
# write sip_uri "from" as avp "from_hdr"
			avp_write("$from", "from_hdr");

And this is after "if method=invite":

#  Remove P-Asserted-Identity if it exist
				#
				remove_hf("P-Asserted-Identity");

				# If Privacy header is set to ID make
anonymous
				if (search("[Pp]rivacy:[^@][Ii][Dd][^@];")
				{
					append_hf("P-Asserted-Identity:
<anonymous at anonymous.invalid>");
	
uac_replace_from("Anonymous","sip:anonymous at anonymous.invalid");
				}

				# Else insert P-Asserted-Identity

				if (!search("[Pp]rivacy:[^@][Ii][Dd][^@];")
				{

				# P-Asserted-Identity Insertion
				#
					avp_printf("s:12",
"<sip:$fU at 64.192.174.8>");
					avp_pushto("$P-Asserted-Identity",
"s:12");
				}

Not sure if this overwrite the previously created AVP or it creates a 
second one with the same name.

Further - what is the problem? Pushing into the header or fetching from DB?

Have you tried it without loading from DB? If this works, make it 
dynamically loading from DB.

btw: I put the PAI into the rpid column in the subscriber table. Thus, 
the s:rpid gets loaded during authentication.
