Hello Daniel,
might be a bug, I did not used this module recently.
I have looked quickly to the code, its rather straightforward. For a test, is the synchronous sending working maybe?
Cheers,
Henning

Hi Henning,
yes I can see the ACR request sent out with wireshark as well as I can see the ACA response coming in from the offline charging server.
I see kamailo parsing the AVPs of the responses too, but when I print the PV, I get null value.

Hello,
just to double check, you’ve setup the diameter “3” peer in your CDP configuration?
Do you see any diameter request created on the network level with tracing tools?
Cheers,
Henning

Subject: [SR-Users] ims_diameter_server: $diameter_response PV is null in the event_route[diameter:response]
Hi list,
I'm using kamailio 5.8 and playing with the ims_diameter_server module, by sending an async diameter request and trying to catch the reponse.
Following the documentation, I'm sending the request with:
route[SEND_ACR]
{
route(PREPARE_ACR);
diameter_request_async("3", "271", "$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?
