THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY.

A new Flyspray task has been opened.  Details are below. 

User who did this - davy van de moere (davyvdm) 

Attached to Project - sip-router
Summary - Coredump on using jsonrpc_request
Task Type - Bug Report
Category - Module
Status - Unconfirmed
Assigned To - 
Operating System - Linux
Severity - Medium
Priority - Normal
Reported Version - Development
Due in Version - Undecided
Due Date - Undecided
Details - 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 on the other hand works like a charm.

Coredump in attach.
