Replacing a message body received with a subsequent message sending out of kamailio
by narayan panigrahi 05 Apr '17

05 Apr '17

Hi All, I have a architecture of pjsip,kamailio,freeswitch and one external server. When kamailio is receiving "407"-proxy authentication required from the external server it sends to freeswitch and received "407" from freeswitch.But when replying back to kamailio the freeswitch is adding some extra headers in that "407". Now I need to send the message from kamailio to pjsip the same thing received from external server.So I need to replace the message received from external server with the message received from freeswitch at kamailio. I am using redis db to store the message.Can anybody help me how to configure the kamailio so that it will replace the message with freeswitch message and send the original message received before i.e. from external server. Any suggestion will be highly appreciated. Thanks, Narayan +91-9035438928

Problems with avp_db_load
by Kevin Bushong 04 Apr '17

04 Apr '17

I am using the avpops module to read from a mysql database to look for CFWD information for the call. When a call is placed, it appears the command avp_db_load attempts to read the file but all values come back as NULL. There are no messages in the log and of course the call does not process correctly. We are using a config that is exactly the same on a 4.3.4 version of kamailio using cento 6.7, with a local version of mysql Ver 14.14 Distrib 5.1.73, that works perfectly. When moving the code to kamailio 4.4.4 on Debian 8, Jessie, mysql Ver 14.14 Distrib 5.5.53 the avp_db_load returns no information. Here is the snippet of the code we are using. Since I am not used to troubleshooting kamailio, please let me know what other information you need. Thanks, Kevin Code snippet: #!ifdef WITH_CFWD xlog ("$TF Call to $rU made it into WITH_CFWD in route[LOCATION] block\n"); # Call forwarding is enabled, so lets do a lookup to pull all AVP's for possible call forwarding types/destinations # Below line should load all AVP's into memory from DB for the username portion of the TO: field from table usr_preferences xlog("script should load from DB usr_preferences next"); avp_db_load("$tU","s/usr_preferences"); # This line i simple want to print to log when the avp load is complete and what the values are (for debug purposes only and should typically be commented out) xlog("DB load should be complete"); xlog("SCRIPT: $TF Call Forwarding Unconditional set to $avp(Unconditional)\n"); xlog("SCRIPT: $TF Call Forwarding NoAnswer set to $avp(NoAnswer)\n"); xlog("SCRIPT: $TF Call Forwarding Busy set to $avp(Busy)\n"); avp_print(); # Check to see if the AVP's are set and if so put them in log for logging purposes if(is_avp_set("$avp(Unconditional)")) xlog("SCRIPT: $TF Call Forwarding Unconditional set to $avp(Unconditional)\n"); if(is_avp_set("$avp(NoAnswer)")) xlog("SCRIPT: $TF Call Forwarding NoAnswer set to $avp(NoAnswer)\n"); if(is_avp_set("$avp(Busy)")) xlog("SCRIPT: $TF Call Forwarding Busy set to $avp(Busy)\n"); t_set_fr(16000, 15000); # set fr invite timeout to 16s and no response at all to 15s to meet the specs for call fowarding no answer ringtime # If Call fowarding Unconditional is set, we need to change the dialed number and sent it off to the original users trunk from subscriber table # Check to see if unconditional is set if(is_avp_set("$avp(Unconditional)")) # Shove this call into route [PSTN_CFWD] Block route("PSTN_CFWD"); Here is the syslog for the same snippet: 09:29 2017 Call to 15703771055 made it into WITH_CFWD in route[LOCATION] block Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: script should load from DB usr_preferences next Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: DB load should be complete Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: SCRIPT: Wed Mar 29 14:09:29 2017 Call Forwarding Unconditional set to <null> Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: SCRIPT: Wed Mar 29 14:09:29 2017 Call Forwarding NoAnswer set to <null> Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: SCRIPT: Wed Mar 29 14:09:29 2017 Call Forwarding Busy set to <null> Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: INFO: avpops [avpops_impl.c:1473]: ops_print_avp(): p=0x7f440ed86f90, flags=0x0113 Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: INFO: avpops [avpops_impl.c:1477]: ops_print_avp(): #011#011#011name=<direction> Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: INFO: avpops [avpops_impl.c:1485]: ops_print_avp(): #011#011#011val_str=<INCOMING / 8>

Re: [SR-Users] ht_db_load_table(): key type must be string (type=6)
by Ginhoux, Patrick 04 Apr '17

04 Apr '17

Hi, A second update for people who started to look at this issue. I have identified the real cause of the problem by looking more in the kamailio log with the debug traces. I discover that it is related to the load of the properties table in the htable. I have the following entries in my mysql db : +-------+----------------+---------------------------------------------------------+------------+----------+ | id | key_name | key_value | value_type | key_type | +-------+----------------+---------------------------------------------------------+------------+----------+ | 0 | VERSION | 120104-1734 | 0 | 0 | | 1 | mmm-retry | 408=Y;502=Y;503=Y | 0 | 0 | | 2 | mgcf-retry | 408=Y;502=Y;503=Y | 0 | 0 | | 3 | max-mmm-retry | 2 | 0 | 0 | | 4 | max-mgcf-retry | 2 | 0 | 0 | | 5 | target-uri | mgcf=10.10.10.10;mmm-legacy=20.20.20.10;mmm=20.20.20.20 | 0 | 0 | | 6 | pike-status | 503 Service Overload | 0 | 0 | | 7 | mgcf-path | 99 | 0 | 0 | | 16 | mmm-nodeid | OPMMMS1VSE01=1;OPMMMS1VSE02=2 | 0 | 0 | | 17 | mmm-node-path | 1=1;2=2 | 0 | 0 | +-------+----------------+---------------------------------------------------------+------------+----------+ In the kamailio.cfg, the << modparam("htable", "htable", "propertiesHash=>size=4;dbtable=properties;") >> command causes the load of the above table in the htable. In the log we can see, that the load is done in the alphabetic order of the key_name and it fails to load the last entry "VERSION" : Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: DEBUG: <core> [db_val.c:169]: db_str2val(): converting BLOB [VERSION] Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: DEBUG: <core> [db_val.c:74]: db_str2val(): converting INT [0] Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: DEBUG: <core> [db_val.c:74]: db_str2val(): converting INT [0] Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: DEBUG: <core> [db_val.c:169]: db_str2val(): converting BLOB [120104-1734] Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: ERROR: htable [ht_db.c:276]: ht_db_load_table(): key type must be string (type=6) If I add a new entry named "WWWWW", then the failure occurs on this entry that is the last alphabetic entry : | 10000 | WWWWW | toto | 0 | 0 | Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: DEBUG: <core> [db_val.c:169]: db_str2val(): converting BLOB [WWWWW] Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: DEBUG: <core> [db_val.c:74]: db_str2val(): converting INT [0] Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: DEBUG: <core> [db_val.c:74]: db_str2val(): converting INT [0] Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: DEBUG: <core> [db_val.c:169]: db_str2val(): converting BLOB [toto] Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: ERROR: htable [ht_db.c:276]: ht_db_load_table(): key type must be string (type=6) Attached the kamailio log for each test.

My first attempt (see kamailio.cfg.ok) shows that the problem doesn't occur. In the second attempt (see kamailio.cfg.ko) I add instructions previously removed from the original .cfg file. I have determined that, depending on the instructions that follows the "modparam("htable", "fetch_rows", 1000)" line, the "key type must be string (type=6)" error occurs or not. In this ko file, if I comment out the following sequence, the error occurs : modparam("htable", "fetch_rows", 1000) #!!ifdef FIXED_ROUTING #modparam("htable", "htable", "mbxrangeHash=>size=4;dbtable=mbxrange;") #!!else #modparam("htable", "htable", "abpqHash=>size=12;dbtable=abpq;") #modparam("htable", "htable", "zabpqHash=>size=12;dbtable=zabpq;") #!!endif modparam("htable", "htable", "propertiesHash=>size=4;dbtable=properties;") I hope my explanation is clearn and there are people who can help me on this problem that causes kamailio to not start.

Configuring Kamailio as a "VoIP traffic reflector"
by Tahiro Hashizume 31 Mar '17

31 Mar '17

Hi there, This e-mail is going to be lengthy and I hope you will not get frustrated (like I am, for different reasons described later) by reading it all from the beginning to the end since I have just warned you :P You have absolutely no need for reading the entire post unless you are crazy enough read about what I do for fun in given circumstances. Basically, I would like Kamailio and Asterisk to run on the same box in such a way that A.)Asterisk listens on eth0 (on 10.1.1.15/24 with ProxyARP enabled) for incoming SIP register requests from VoIP-ATAs B.)Kamailio listens on five IP addresses on dummyN which has 10.1.1.1N/32 (N=0-4, so dummy0 has 10.1.1.10/32, for example) making five SIP+RTP sessions to the same remote host to appear as if they are from five different hosts - so that a single instance of Asterisk running on debian may be registered (through Kamailio) on the same remote host by using five different accounts and source IP addresses. I know Asterisk alone cannot do this (even by running multiple instances of it) and that there have to be five instances of both SIP-Proxy and RTP-Proxy so that the source address can be literally spoofed. Should be simple, but so far cannot find good sources of reference. I need your advice. Thanks in advance. << Backgrounds - read only if you are curious >> The so-called frustration is when your needs are not realized due to technological limitations. I have years worth of frustration on the VoIP setup at home and that's totally NOT your fault. Written below for those who happen to be curious should sound interesting, so here is the situation I'm facing; I'm in Japan and our infrastructure is well within the definition of NGN which in my case includes a low-latency VoIP to replace the traditional PSTN. (NTT will end ISDN in 2020, copper-line PSTN in 2025, as announced so far.) The service is provided by NTT (former state-run telecom) of Japan and works on FTTH which carries: a.)PPPoE for those who wish to get IPv4&IPv6 connectivity - which for the most part is so that users get to choose their favorite ISP. b.)WAN-reachable IPv6 traffic c.)WAN-unreachable IPv4 for SIP based services (address blocks reserved and announced by AS9595) Given the fact that b.) and c.) are only applicable (optionally and respectively) to those who signed up for the native-IPv6 (we call it IPoE, oddly) service and to those who signed up for the VoIP service, it's essentially an L2 transport service for PPPoE to your ISP - very much like the way we had our phone-line and ISP (dial-up) separately signed up for in the old days (hence I call it the access-line service). I've made a switch over to VoIP-based PSTN from the copper-line in April 2011 after seeing that copper-line PSTN served no better in case of emergency like 3.11 when people want to call others to see if their loved one are okay - on the evening through the night of March 11 2011, our traditional PSTN stayed at its capacity limits while VoIP-based means of communication (incl. Skype, surprisingly) stayed intact. That was the wake-up call. Now, upon signing up for the VoIP service, the user receives a box so called HGW (stands for Home Gateway) which is very much a SIP+RTP UA on its WAN side and SIP+RTP server on LAN side (up to 5 UAs may register if the UA supports "sip session-timer"). And this HGW is being the pain that drove me to writing this e-mail - it only allows one SIP-register per IP address. Further, looking into the specs requirements for HGW published by NTT (=there's a centralized documentation for it since the designs and manufacturing of HGW is split across several companies), there's a part which basically says: "One SIP register to HGW from a UA on LAN should be able to handle (but not limited to) one data session. An UA on HGW's LAN side may support multiple-data session per SIP register(optional)." - which to me reasonably explains why my HGW only allows one SIP-register per IP address. My gyess is that the unwritten assumption here is "one sip register"="one physical phone", which is quite understandable. Regarding the fact that NTT optionally provides services like: 1.)additional phone numbers 2.)multi-data sessions(RTP for voice, for example) ...on one trunk. This, and also in accordance with the technical specs. requirements for HGW above means supporting multiple RTP sessions either terminated or originated by an Asterisk box which sits on the HGW's LAN side requires that a single instance of Asterisk on a debian box somehow uses multiple IP addresses (with or without the use of other software). The simplest way of doing this (to me) seemd like running five instances of RTP(proxy)+SIP(proxy) which will each listen on one of five IP addresses, to which the Asterisk instance in question could establish one session of SIP+RTP each. The idea seemed simple enough, but there did not seem like good selections of software years ago. I have once given up on the implementation years ago, altered the NTT-supplied HGW with a third-party product (NVR500 by YAMAHA which on its LAN behaves as a MGCP+RTP server) in order to maximize the stability of the phone system. This was due to the fact that the x86-box I was using was hardware-unstable and that the HGW's behavior was something I did not like dealing with (recently solved). I've decided to make a come-back to Asterisk recently since I recently started using hylafax running on a RasPi with RS232 modem hooked up to it but with missing support for CID since the Japanese equivalent of CID (we call it Number-Display) does not follow the Bellcore standards and the modem I use only supports Bellcore standards- going VoIP again and running iaxmodem could solve this issue. -------------------------------------------- Tahiro Hashizume Department of Electrical and Electronic Engineering at Tokyo Denki University 5 Senju-Asahi-cho Adachi-ku Tokyo, JP1208551 Japan --------------------------------------------

[SIP Transaction] Handle Cancel message
by Hai Bui Duc Ha 30 Mar '17

30 Mar '17

Hi all, I have problem when use module pusher on Kazoo. The user after receive call from pusher can not receive the Cancel message if have another people pick up this phone.

log_custom module question
by Anonim Stefan 29 Mar '17

29 Mar '17

Hi, I'm trying some logging via UDP, using log_custom module. I've noticed that the logs are always sent through the first interface in the config "listen=" rows. Now, is there a way to listen on that interface, in order to log_udp() on it, without being able to send/receive any SIP on it? (i.e. disabling SIP capability and use it only for logging via UDP) Thank you, Stefan
