I have TEXT call from cust1@somedomain to Kamailio. I have an agent who is logged in, but is not in any call yet. I want now refer cust1@somedomain to talk to agent directly. How do I do that? I tried - dlg_bridge("$dlg(from_contact)", "$var(agentSipAddress)",""); I get an "audio call" from "Kamailio" to customer, but nothing happens on the agent side. I tried "dlg_refer" as well but nothing happens at all. I am attaching Kamailio log / my config files for reference. Should I handcraft "Refer" message using uac module and send to "customer" instead? Please suggest.

acces $dlg_var in failure_route

by Diego Nadares

Hi guys, I'm trying to access dialog vars in failure_route with no success. Dialog exists but vars are null and I'can modify them either. Is there any restriction? if ($dlg_var(v1) == 0){ $dlg_var(v1) = "1"; if (is_known_dlg()){ xlog("L_NOTICE", "negative_reply $ci $T_rpl($si) $dlg_var(v2)"); $dlg_var(v2) = $T_rpl($si); } } Log Apr 26 12:36:26 drwsip02 /usr/local/sbin/kamailio[27223]: NOTICE: <script>: negative_reply 6daf5e8d-f47972c1(a)172.31.4.21 * <null>*

Oracle and package function

by Diego Nadares

Hi list, I compiled db_unixodbc and sqlops to connect with oracle db. I have a function that has dml inside. Because of this I can't just execute 'select pkg.function(a, b) from dual'. I'm trying with BEGIN / END. The row is inserted but always are log errors: Apr 29 02:41:57 dwsipm03 /usr/local/sbin/kamailio[7868]: ERROR: db_unixodbc [res.c:60]: db_unixodbc_get_columns(): no columns returned from the query Apr 29 02:41:57 dwsipm03 /usr/local/sbin/kamailio[7868]: ERROR: db_unixodbc [res.c:261]: db_unixodbc_convert_result(): getting column names failed Apr 29 02:41:57 dwsipm03 /usr/local/sbin/kamailio[7868]: ERROR: db_unixodbc [dbase.c:211]: db_unixodbc_store_result(): failed to convert result Apr 29 02:41:57 dwsipm03 /usr/local/sbin/kamailio[7868]: ERROR: <core> [db_query.c:188]: db_do_raw_query(): error while storing result Apr 29 02:41:57 dwsipm03 /usr/local/sbin/kamailio[7868]: ERROR: sqlops [sql_api.c:265]: sql_do_query(): cannot do the query [DECLARE ret CURSOR] My query: sql_query("cb","DECLARE ret CURSOR; BEGIN ret := pkg_partitioning.insert(True,'1'); END;"); I tried with other functions and no matter what type returns the oracle function; always logs errors. It's like unixodbc is waiting for a result with rows. Any hint? Thanks in advance, Diego

Kamailio 4.4 NAT issue, nathelper I can not get to work

by Jason Davies

Hello I have my servers behind a NAT, with servers that make a call with bypass media / direct media all works fine. But when my media servers need to process audio I'm having issues. Looking at the SDP my local IP of the server is in there. I changed my config to add the nethelper.so and add the below: # ----- NAT Helper ----- #!ifdef WITH_NAT #modparam("nathelper", "rtpproxy_sock", "udp:127.0.0.1:7722") modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) #modparam("nathelper", "sipping_bflag", 7) #modparam("nathelper", "sipping_from", "sip:pinger@kamailio.org") #modparam("registrar|nathelper", "received_avp", "$avp(i:80)") #modparam("usrloc", "nat_bflag", 6) #!endif In my route I added: if (search("User-Agent: FS Box") {fix_nated_sdp("3");};

TLS SIP packet tracing and visualization

by Giovanni Maruzzelli

Hello fellows, after some experimentation with various tools, I come out with a little shell tool that maybe can be useful to you too. It can only work with non-forward secrecy ciphers, obviously, and only if is started before the client do the initial TLS handshake (eg, just restart the client). Forward secrecy cannot be decrypted after fact, so don't waste effort. An example of ciphers that can be decrypted are the "AES256-SHA" openssl cipher group. You can use ssldump to check what cipher is used by serverhello. Enjoy, make it better, and share it :) #!/bin/bash # brought to you by Giovanni Maruzzelli # SERVERIP="192.168.1.150" SERVERPORT="5061" PRIVKEY="/etc/certs/privkey.pem" STDERR2DEVNULL=" 2>/dev/null " REGEX="notyet" if [ -z "$1" ]; then REGEX="\\\.*" else REGEX="$1" fi FILTER="ssl.app_data and sip matches" FILTER2="$FILTER \"$REGEX\"" FILTER3="'$FILTER2'" ARGUMENT="-i 1 -Y $FILTER3 -E header=y -T fields -e frame.number -e frame.time -e frame.time_delta_displayed -e ip.src -e ip.dst -e sip.Status-Line -e sip.Request-Line -e sip.msg_hdr -l -d tcp.port\=\=5061,sip -o \"ssl.keys_list: $SERVERIP,$SERVERPORT,sip,$PRIVKEY\" $STDERR2DEVNULL | sed -u 's/\t/\n/g' | sed -u '/^$/d' | sed -u 's/^[0-9]*$/\n==&==============================/g'" echo "" echo "NB: if it do not works, edit script so that STDERR2DEVNULL=\" \" and try again" echo "" echo "NB: remember to quote and escape match patterns, using triple slash" echo " eg, for matching 1010(a)pbx.example.com, use \"1010(a)pbx.example.com \"" echo " eg, for matching anything, use \"\\\\\\.*\"" echo " eg, for matching *98, use \"\\\\\\*98\"" echo "USAGE: $0 \"\\\\\\*98(a)pbx.example.com\"" echo "" case "$1" in -help|--help|?) exit 0 ;; *) echo "THIS TIME WE'RE DOING:" echo "tshark $ARGUMENT" echo "" bash -c "tshark $ARGUMENT" ;; esac -- Sincerely, Giovanni Maruzzelli OpenTelecom.IT cell: +39 347 266 56 18
