[OpenSIPS-Users] URI PARSING

[Richard Revels]

        #this next part logs an error if the message has no expires info (scanner messages sent directly to proxy for instance)
        if(is_present_hf("Expires"))
                $avp(i:10) := $hdr(Expires);
        else
                $avp(i:10) := $ct.fields(expires);
        if( $avp(i:10)  == "0" )
        {
		...


Speaking of this, using a min_expires param to the registrar module seems to defeat allowing users to unregister by sending a expires of zero.  I seem to remember it gets bumped to the min value.  If true, I think there should be a check added in the minimum time check to let zero sneak through as is and remove the user from userloc table.
