[OpenSER-Users] P-Asserted-Identity pseudo-variable

[Watkins, Bradley]

The documentation for pseudo-vars in 1.2.x says that $ai is the URI for
P-Asserted-Identity.

http://openser.org/dokuwiki/doku.php/pseudovariables:1.2.x#uri_in_sip_re
quest_s_p-asserted-identity_header

However, if I try to use this in my scripts I get this in the log:

ERROR:avpops:fixup_subst: bad attribute name <$ai>

Is this a bug or a documentation error?  Is there some other pseudo-var
that should be the PAI?

FWIW, I'm currently running 1.2 branch post-1.2.1 but not updated since
before 1.2.2 came out.
