Details - i'm testing uac module with a did provider, apparently it works the first
register, when it's going to refresh the session the register packed don't send
the proxy-authorization header.

My kamailio is 4.0, the debian wheezy repository

this is my parameter config:

#!ifdef WITH_UAC
#---------- uac params ----------#
modparam("uac", "reg_db_url",DBURL)
modparam("uac", "reg_timer_interval",60)
modparam("uac", "reg_retry_interval",120)
modparam("uac", "reg_db_table", "uacreg")
modparam("uac","credential","username:domain:password")
modparam("uac","auth_realm_avp","$avp(i:10)")
modparam("uac","auth_username_avp","$avp(i:11)")
modparam("uac","auth_password_avp","$avp(i:12)")
modparam("uac","restore_mode","auto")
modparam("uac", "reg_contact_addr", "xx.xx.xx:5060")
#!endif

this is the route block:

  if(uac_reg_request_to("$fU", 1))
        {
        xlog("L_NOTICE", "Found remote user [$rU] on [$rd] via
[$du]");
        t_on_failure("REMOTE_AUTH");

        t_relay();
        }

         inside route[LOCATION] at the end:

#!ifdef WITH_UAC

        if(uac_reg_lookup("$rU", "$ru")) {
        xlog("request from a remote SIP provider [$ou => $ru]\n");
        }
                lookup("location");

#!endif

failure_route[REMOTE_AUTH] {
        if ($T_reply_code == 401 or $T_reply_code == 407) {
                xlog("L_NOTICE", "Remote asked for authentication");
                uac_auth();
                }
        }

this is the error log by syslog
