[SR-Users] Diameter AVP handling from kamaiio.cfg

[Zoltán Miricz]

Hi Carsten,

Thank you very much for your response!
Sadly for the UAR, LIR, SAR are not providing these kind of error codes.
As you can see only -1 coming back and not
Jan  4 06:17:15 localhost journal:

<script>: $avp(s:uaa_return_code) = -1

route[REG_UAR_REPLY]
{
    xlog("$$avp(s:uaa_return_code) = $avp(s:uaa_return_code)\n");
    #this is async so to know status we have to check the reply avp
    switch ($avp(s:uaa_return_code)){
            case 1: #success
                    if (I_scscf_select("0")){

In my case it should be Error_User_Unknown(5001) and from the above example
it's visible that from the cxdx_uar.c it's visible, but when the config
script get's the variable it's already -1.

*Cheers,*
