Hi Daniel,

the module was developed by a former colleauge. As I found out it queries the Database to check some Info about the clients. If they have set Call Forwarding or they were Blacklisted or to check their Numbers' Prefixes.
So as I know no authentication tasks. I noticed that the obsoleted avp_db_query() was used. I will try to use sql_xquery() instead and update you.

Although I am not sure it is the cause for such Crash because Kamailio is answering the REGISTER with "SIP/2.0 407 Proxy Authentication Required" then immediately finishing with "SIP/2.0 500 I'm terribly sorry, server error occurred (1/SL)"
I will provide you with more Info soon. Thanks for you patience with a Kamailio Beginner.

Besr regards
Abdul

Hello,

the frame 0 in bt full output has no details, so somehow the symbols stack is broken. Does any of your custom modules have anything to do authentication? Fetching username/password, or proving different encryption algorithm?

Cheers,
Daniel

Hello,

the error message from dispatcher is not relevant for runtime, it is saying that you have to set some parameters to dispatcher module (those with avp names) because you use ds_next_dst()/ds_next_domain() -- without those parameters, you can't do re-routing using failure_route and dispatcher functions.

From the logs, it is nothing showing the cause of the issue, could be your own modules or something else.

Try to generate a corefile and then get the backtrace with gdb. To generate the corefile:

 - run "ulimit -c unlimited" in the terminal where you start kamailio
 - run kamailio as root user
 - reproduce the issue
 - there should be a log message saying that the "core was generated"
 - get the output of "bt full" from gdb inspecting the core file

Cheers,
Daniel

Hi Everyone,

I am trying to start kamailio 5.1.4 with two own modules. After /etc/init.d/kamailio start , I am getting one error of the dispatcher module and bunch of warrnings because of missed reply and failure routes.

The first error before crashing is:

ERROR: dispatcher [dispatcher.c:814]: ds_warn_fixup(): failover functions used, but required AVP parameters are NULL -- feature disabled


Later on, when I am trying to register a user (from a soft phone) i am getting the following:

Regarding to the first error of the dispatcher module i could not find out which calibration i can follow with its parameters to get rid of this error.

Regarding the jasonrpcs and the last two erros, here are my configuration in kamailio.cfg:

#/* set the path to RPC fifo control file */
modparam("jsonrpcs", "fifo_name", "/tmp/kamailio_jsonrpc.fifo")
modparam("jsonrpcs", "fifo_mode", 0755)
modparam("jsonrpcs", "fifo_group", "kamailio")
modparam("jsonrpcs", "fifo_user", "kamailio")


#/* set the path to RPC unix socket control file */
modparam("jsonrpcs", "dgram_socket", "/tmp/kamailio_rpc.sock")
modparam("jsonrpcs", "dgram_mode", 0755)
modparam("jsonrpcs", "dgram_user", "kamailio")
modparam("jsonrpcs", "dgram_group", "kamailio")

I think the root cause is even beyond the dispatcher and jsonrpcs modules setting.

Please check the attached where you can find my complete log file after starting Kamailio.

Best regards
Abdulaziz
