Hi folks,
I came into a problem with evapi module, while I was trying to make the
CGRateS tutorial work. It does not send any messages at all.
Taken steps:
I start kamailio with debug=3.
I start:
CGRates (on the kamailio machine)
telnet 192.168.30.29 8448 (from my PC)
tcpdump port 8448 -A -s0 -i any (on the kamailio machine)
Telnet command successfully connects to kamailio. Kamailio yells:
root@cgrates:/opt/kamailio/src/kamailio-4.4/kamailio# 11(12205) DEBUG:
evapi [evapi_dispatch.c:453]: evapi_accept_client(): new connection -
pos[1] from: [192.168.30.1:40312]
11(12205) INFO: <script>: Starting Evapi connector srcaddr 192.168.30.1
srcport 40312 condix 1
11(12205) DEBUG: htable [ht_var.c:90]: pv_set_ht_cell(): set value for
$sht(cgrconn=>cgr)
A similar message is printed when CGRateS connects in.
Afterwards I make a call to Kamailio. INVITE is routed to a following
command:
evapi_async_relay("{\"event\":\"CGR_AUTH_REQUEST\",
\"tr_index\":\"$T(id_index)\",
\"tr_label\":\"$T(id_label)\",
\"cgr_reqtype\":\"$dlg_var(cgrReqType)\",
\"cgr_tenant\":\"$dlg_var(cgrTenant)\",
\"cgr_account\":\"$dlg_var(cgrAccount)\",
\"cgr_destination\":\"$dlg_var(cgrDestination)\",
\"cgr_setuptime\":\"$TS\",
\"cgr_computelcr\":\"true\"}");
Now the kamailio writes:

However no reply from CGRateS comes, tcpdump is quiet (no message was sent
or received), as well as my testing telnet session (nothing is received).
The network doesn't seems to be the issue, as when I write "6:Efelin," to
the telnet session, kamailio executes the route
event_route[evapi:message-received]

I wasn't able to find anything that might block the connection. Can anyone
point me to, how to debug this issue further?
Thanks for any advice.
Kind regards
