Hi list,
I'm using kamailio 5.8 and playing with the ims_diameter_server module, by
sending an async diameter request and trying to catch the reponse.
Following the documentation, I'm sending the request with:
route[SEND_ACR]
{
route(PREPARE_ACR);
diameter_request_async("3", "271", "$var(json_acr)");
}
route[PREPARE_ACR]
{
# here I build the AVP list in JSON
$var(json_acr) =
"[{"avpCode":277,"vendorId":0,"Flags":64,"int32":0},{...},{...}]";
}
event_route[diameter:response] {
xlog("Reply to diameter request is: '$diameter_response'\n");
}
The ACR request is successfully sent and the the server is replying with ACA.
The list of AVP are properly parsed, but when I enter the event_route to print
the response, I get the $diameter_response = 'null':

Is there something I miss to set/configure?
