Final reply code is wrong in case of 302 and 486 busy
by Marco Capetta 03 Aug '18

03 Aug '18

Hello, we have a problem of final reply code in case of 302 and then 486 busy. This is our scenario: A, B and C are subscribers. A ----------> Kamailio ----------> B Kamailio <---302---- B Kamailio -----------------------> C Kamailio <---486----------------- C A <---302---- Kamailio Expected behavior: Kamailio should reply to A with 486, as C was busy, and not 302. We have kamailio v5.1.4 In the call to B we set both failure and branch_failure: t_on_failure("failure_route"); t_on_branch_failure("failure_redirect"); in order to handle the 302 redirect per branch with: event_route[tm:branch-failure:failure_redirect] { if($T_reply_code == 301 || $T_reply_code == 302) { do redirect ... } } and the final failure with: failure_route[FAILURE_ROUTE_LOCAL] { do something ... } Since we have 'modparam("tm", "failure_reply_mode", 3)' my expectation is to get the winning reply from the branch of last step. Is there any configuration I'm missing? Since we manage the redirect with a branch-failure, is the winning reply calculated in a different way? Thanks Marco

Good Morning all, When I do get Kamailio to compile with MySQL 8, I encounter the following issue when running "kamdbctl create" ERROR 1449 (HY000) at line 1: The user specified as a definer ('mysql.infoschema'@'localhost') does not exist WARNING: Your current default mysql characters set cannot be used to create DB. Please choice another one from the following list: Any ideas? Thank you.

is_method not matching message type KDMQ breaking DMQ bus. (master branch)
by Asgaroth 02 Aug '18

02 Aug '18

Hi All, I've come across and oddity whereby my is_method("KDMQ") checks are not matching. I'm testing with kamailio master: version: kamailio 5.2.0-dev6 (x86_64/linux) a16272 flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144 MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: a16272 compiled on 15:27:21 Jul 31 2018 with gcc 7.3.1 Sample routing logic: request_route { route("InitialMessageChecks"); exit; } route[InitialMessageChecks] { xlog("L_INFO", "Received message type $rm from $si:$sp on $Ri:$Rp"); if ( is_method("KDMQ") ) { xlog("L_INFO", "KDMQ check passed."); } if ( is_method("OPTIONS") ) { xlog("L_INFO", "OPTIONS check passed."); } if ( is_method("SUBSCRIBE") ) { xlog("L_INFO", "SUBSCRIBE check passed."); } } In the logs I am only receiving the 1st log line in the initial message checks route for message types of KDMQ, eg: INFO: <script>: Received message KDMQ from 1.1.1.1:5060 on 1.1.1.2:5060 INFO: <script>: Received message KDMQ from 1.1.1.3:5060 on 1.1.1.2:5060 I never seem to hit the is_method check log line when the method type is KDMQ. I do see the options/subscribe logs though: INFO: <script>: OPTIONS check passed. INFO: <script>: SUBSCRIBE check passed. nothing for KDMQ. Reason for asking is: this check never matches and breaks the dmq bus: if ( is_method("KDMQ") ) { if ( dmq_is_from_node() ) { dmq_handle_message(); exit; } else { exit; } } Any thoughts, or am I going crazy :) Thanks

Re: [SR-Users] Method Destination Variable
by Duarte Rocha 02 Aug '18

Greetings, I thought about that but i wasn't sure it would be safe. But, in this case, the Request-URI domain will be the only place where Kamailio will look to find out the destination right within the dialog right? I'm going the statelless way, so that might be the correct answer. Thanks for your help

get_out_socket(): no socket found
by Ilie Soltanici 02 Aug '18

Daniel, Not, those IP are in a different subnet. There is a firewall - running on a different device. Ping and SIP Messages are going very well from 2.2.2.2 to 8.8.8.8. I was able to solve this issue by disabling mhomed and set "listen" external interface with IP address 2.2.2.2 on top in the configuration file. Now, Kamailio is starting without any errors and is registering to the upstream provider, but I just I am wondering if it's possible to specify an outgoing socket for uac module in the configuration file? Thank you.

Daniel, Yes, IP Address has been edited, 2.2.2.2 and 8.8.8.8 are not real IP Address-es, this is just to show that those IP are external IP's. Regards, Ilie

Method Destination Variable
by Duarte Rocha 01 Aug '18

01 Aug '18

Greetings, I have a Kamailio server set up without Registers. I'm using Dispatcher module for balancing and selecting the destinations. I need to do some changes in the message according to the chosen destination. If it's the first INVITE, after Dispatcher operations, i can do it using $dd or $du variables. However, in later messages, like a BYE, i can't seem to access the method's destination IP. Is there any variable that i'm missing? I've tried $route_uri but it only returns the kamailio's own IP, since it's the only IP in the "Route" header. Thanks in advance, Cheers

Hi All, I'm unable to register an extension to the Upstream Provider by using uac module. Getting the following error: *Jul 31 15:49:39 k1-core1 k1[13146]: ERROR: <core> [core/forward.c:181]: get_out_socket(): no socket found* *Jul 31 15:49:39 k1-core1 k1[13146]: ERROR: <core> [core/forward.c:183]: get_out_socket(): no corresponding socket found for(udp:8.8.8.8:5060 <http://8.8.8.8:5060>)* *Jul 31 15:49:39 k1-core1 k1[13146]: ERROR: tm [ut.h:317]: uri2dst2(): no corresponding socket found for "svr04.nuacom.net <http://svr04.nuacom.net>" af 2 (udp:8.8.8.8:5060 <http://8.8.8.8:5060>)* *Jul 31 15:49:39 k1-core1 k1[13146]: ERROR: tm [uac.c:449]: t_uac_prepare(): no socket found* *Jul 31 15:49:39 k1-core1 k1[13146]: ERROR: uac [uac_reg.c:1161]: uac_reg_update(): failed to send request for [1050]* Kamailio is listening on 2 interfaces: [root@kamailio user]# /usr/local/sbin/kamcmd core.sockets_list { socket: { proto: udp address: 10.1.1.11 ipaddress: 10.1.1.11 port: 5060 mcast: no mhomed: no } socket: { proto: udp address: 2.2.2.2 ipaddress: 2.2.2.2 port: 5060 mcast: no mhomed: no } mhomed is enabled in the configuration file: *mhomed=1* I'm not using ' force_send_socket' anywhere in the configuration file. This is the uac module configuration: modparam("uac", "reg_keep_callid", 1) modparam("uac", "reg_contact_addr", "2.2.2.2") modparam("uac", "reg_db_url","cluster://kamailio") If i'm disabling mhomed from configuration file - i don't receive any errors - but then kamailio is trying to send the message to the external server (8.8.8.8) through internal interface (10.1.1.1). Thank You.
