[Serusers] sip-session attribute

[AJ Grinnell]

I am using SER 0.8.14, FreeRadius 1.0.0 and the latest version of
radiusclient. When I try to start SER, I get

"ERROR: auth_radius: cant get code for the Sip-Session attribute value"

I found some posts about this issue, but the replies did not help me.
My dictionary file includes the standard values, sip, and cisco
values. Is this just a line I need to add to my dictionary file as an
avp? If so, what is the correct avp for sip-session, I cant find it
anywhere. Thank you.
