Gents,
I’ve stumbled upon a coredump when using jsonrpc_request.
I might be expecting the wrong things from jsonrpc_request. I was hoping to use
it in combination with CNXCC, and have jsonrpc_request get a maximum duration
for every call, as a fraud avoidance mechanism.
I tried this with the branch 4.1 and master. Both behave identical.
So from the kamailio-basic.cfg example, I just added this line around line 350
(just above route(SIPOUT)):
jsonrpc_request("bar.sendsms", "{'ru':'$rU','rb':'$rb'}", "JSONRESPONSE",
"JSONERROR", "$var(result)");
Doing a ngrep on the netstrings I have:
interface: venet0 (127.0.0.2/255.255.255.255)
filter: (ip or ip6) and ( port 7080 )
#
T 10.66.8.42:44995 -> 192.168.60.45:7080 [AP]
94:{ "id": 2, "jsonrpc": "2.0", "method": "bar.sendsms", "params": { "ru": "",
"rb": "" } },
##
T 192.168.60.45:7080 -> 10.66.8.42:44995 [AP]
43:{"jsonrpc": "2.0", "result": "12", "id": 2},
####^Cexit
7 received, 0 dropped
I do get some results from the JSONRESPONSE route.
But when launching a call, or when sending just a register packet, kamailio
gives up with:

Using the jsonrpc_notification works like a charm.
I got coredumps of it, if someone is interested.
Side questions are offcourse, am I aiming to use jsonrpc_request for the
correct purpose? Are there any other good alternatives? (next to using plain db
queries?)
Grtz,
Davy
