There is few configuration that not works in the documentation for Kamailio 3.2.0
For example: in
http://kamailio.org/docs/modules/3.2.x/modules_k/acc.html
modparam("acc", "radius_config",
"/etc/radiusclient/radiusclient.conf")
modparam("acc", "radius_extra", "via=$hdr(Via[*]);
email=$avp(s:email)")
Give errors : set_mod_param_regex: parameter <radius_extra> not found in module
<acc>
Thanks to review the deprecated parameters modules
