Contacts replacing each other when registering
by Sebastian Damm 08 Nov '16

08 Nov '16

Hi, we are running a Registrar server with 4.4.3, the registrar module is configured with the following parameters: modparam("registrar", "max_contacts", 50) modparam("registrar", "use_path", 1) modparam("registrar", "path_mode", 0) modparam("registrar", "path_use_received", 1) modparam("registrar", "received_avp", "$(avp(i:801))") modparam("registrar", "default_expires", 600) modparam("registrar", "min_expires", 60) modparam("registrar", "max_expires", 600) modparam("registrar", "gruu_enabled", 0) A customer has configured 4 phones with the same username. Normally, all 4 phones would be visible in the location database, and incoming calls would fork out to all 4 phones. However, only one of the devices is always online, the others always replace each other on each registration. Client details: * All phones are snom 715 devices with the same firmware version. * All phones sit behind the same router. Registrations: client 1: * Via: SIP/2.0/UDP 192.168.208.91:35812;branch=z9hG4bK-4q0mmxgu6gm7;rport * Contact: <sip:1794388e3@192.168.208.91:35812;line=gicode6v>;reg-id=1;q=1.0;+sip.instance="<urn:uuid:0a14174a-77be-424c-864e-0004137F1C9D>" client 2: * Via: SIP/2.0/UDP 192.168.208.90:41331;branch=z9hG4bK-3cbxdvbmk0di;rport * Contact: <sip:1794388e3@192.168.208.90:41331;line=0j6veso8>;reg-id=1;q=1.0;+sip.instance="<urn:uuid:0a14174a-77be-424c-864e-0004137F1C9D>" client 3: * Via: SIP/2.0/UDP 192.168.208.92:5360;branch=z9hG4bK-4drsogakez94;rport * Contact: <sip:1794388e3@192.168.208.92:5360;line=0n7jfzih>;reg-id=1;q=1.0;+sip.instance="<urn:uuid:0a14174a-77be-424c-864e-0004137F1C9D>" client 4: * Via: SIP/2.0/UDP 192.168.208.93:5260;branch=z9hG4bK-1ci0qia3yxyl;rport * Contact: <sip:1794388e3@192.168.208.93:5260;line=mh9sgxa1>;reg-id=1;q=1.0 Only client 4 is reachable all the time. The other 3 clients replace other registrations. So after client 1 registers, the contacts returned in the 200 OK looks like this: Contact: <sip:1794388e3@192.168.208.91:35812;line=gicode6v>;q=1;expires=600;received="sip:1.2.3.4:6411";+sip.instance="<urn:uuid:0a14174a-77be-424c-864e-0004137F1C9D>";reg-id=1, <sip:1794388e3@192.168.208.93:5260;line=mh9sgxa1>;q=1;expires=303;received="sip:1.2.3.4:8923" And after client 2 registers, the contacts returned in the 200 OK looks like this: Contact: <sip:1794388e3@192.168.208.90:41331;line=0j6veso8>;q=1;expires=600;received="sip:1.2.3.4:49061";+sip.instance="<urn:uuid:0a14174a-77be-424c-864e-0004137F1C9D>";reg-id=1, <sip:1794388e3@192.168.208.93:5260;line=mh9sgxa1>;q=1;expires=301;received="sip:1.2.3.4:8923" So you see, one contact stays the same, the other one gets replaced. Does anybody know what could cause this kind of behavior? I think, it could be GRUU. I see that those three clients all send the same GRUU parameter. From my understanding, this UUID should be different from client to client. I don't know whether this is a bug in the snom firmware always sending the same GRUU UUID or whether som "intelligent" SIP aware router is putting this in the Contact header. However, since we have disabled gruu for the registrar module (see above), I think, Kamailio should ignore it. Ideas? Thanks in advance. Best Regards, Sebastian

Hi, Our Kamailio server is crashing once per week, with following error: Oct 1 06:25:06 kamailio kernel: [26982632.803789] Out of memory in UB 210: OOM killed process 12261 (kamailio) score 0 vm:1614768kB, rss:280200kB, swap:131408kB Core dump was never created, probably it is because of my environment, but I will try to get it. Server constantly eats memory, maybe some kind of memory leak? Any help is highly appreciated! Jurijs

Malformed To header, or?

Hi! Having some issues with Kamailio 4.3 reporting a malformed header, but I cannot seem to figure out what's wrong.

Is it as simple as the number +123456789 is not enclosed with ", i.e. it should be sent as "+123456789"? A similar issue seen, which for some reason doesn't create an ERROR, is when Kamailio receives a reINVITE looking like this which it's supposed to proxy: To: +123456789 <sip:123456789@127.0.0.1>;tag=SD1sf9001--45026-530b969-77c7543f-530b969. which is rewritten into: To: +123456789 <sip:123456789@127*0-)'.:/)&7'...0;user=phone>;tag=SD1sf9001--45026-530b969-77c7543f-530b969. and sent out.. Thanks for your help, /Tobias

Configuring/Integrating Kamailio Open IMS with FHoSS
by Olvera, Victor 04 Nov '16

04 Nov '16

How does one configure Kamailio Open IMS and FHoSS? In other words, how does one configure IMS and FHoSS so that when soft calls are made they must be processed by the FHoSS before they go through the Open IMS server? Great regards, Victor Olvera

Kamailio TLS client config selection
by Sergey Basov 02 Nov '16

02 Nov '16

Hi Daniel. After some try to configure kamailio 4.4.3 to act as SPI TLS client for Cisco SIP TLS gateways I have found one issue. If I do client configuration for tls [client:10.1.23.19:5061] verify_certificate = yes ca_list = /etc/kamailio/CAs/ca1.pem [client:10.1.23.29:5061] verify_certificate = yes ca_list = /etc/kamailio/CAs/ca2.pem [client:default] verify_certificate = no require_certificate = no Kamailo always do default profile selection (I do configuration without server_name or server_id, with it kamailio works fine but there are some troubles to make selection of this parameters from config script, I need additional checks and queries) after some research in tls module source code I have added some debug information in file tls_server.c: if (c->flags & F_CONN_PASSIVE) { state=S_TLS_ACCEPTING; dom = tls_lookup_cfg(cfg, TLS_DOMAIN_SRV, &c->rcv.dst_ip, c->rcv.dst_port, 0, 0); } else { state=S_TLS_CONNECTING; sname = tls_get_connect_server_name(); srvid = tls_get_connect_server_id(); // ------------------------------------------------------------- DBG("Entered client config loockup (c->rcv.dst_port %d)\n", c->rcv.dst_port); DBG("Entered client config loockup (&c->rcv.dst_ip %s)\n", ip_addr2a(&c->rcv.dst_ip)); DBG("Entered client config loockup (c->rcv.src_port %d)\n", c->rcv.src_port); DBG("Entered client config loockup (&c->rcv.src_ip %s)\n", ip_addr2a(&c->rcv.src_ip)); // ------------------------------------------------------------- dom = tls_lookup_cfg(cfg, TLS_DOMAIN_CLI, &c->rcv.dst_ip, c->rcv.dst_port, sname, srvid); } After making Oct 26 09:23:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: <core> [parser/msg_parser.c:597]: parse_msg(): method: <INVITE> Oct 26 09:23:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: <core> [parser/msg_parser.c:599]: parse_msg(): uri: <sip:9098@10.1.23.19:5061;transport=TLS> Oct 26 09:23:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: <core> [parser/msg_parser.c:601]: parse_msg(): version: <SIP/2.0> I see Oct 26 09:23:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: <core> [ip_addr.c:229]: print_ip(): tcpconn_new: new tcp connection: 10.1.23.19 Oct 26 09:23:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: <core> [tcp_main.c:985]: tcpconn_new(): on port 5061, type 3 Oct 26 09:23:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: <core> [tcp_main.c:1295]: tcpconn_add(): hashes: 1394:0:0, 1 Oct 26 09:23:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: tls [tls_server.c:197]: tls_complete_init(): completing tls connection initialization Oct 26 09:23:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: tls [tls_server.c:160]: tls_get_connect_server_name(): xavp with outbound server name not found Oct 26 09:23:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: tls [tls_server.c:140]: tls_get_connect_server_id(): xavp with outbound server id not found Oct 26 09:23:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: tls [tls_server.c:219]: tls_complete_init(): Entered client config loockup (c->rcv.dst_port 40123) Oct 26 09:23:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: tls [tls_server.c:220]: tls_complete_init(): Entered client config loockup (&c->rcv.dst_ip 10.1.23.23) Oct 26 09:23:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: tls [tls_server.c:221]: tls_complete_init(): Entered client config loockup (c->rcv.src_port 5061) Oct 26 09:23:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: tls [tls_server.c:222]: tls_complete_init(): Entered client config loockup (&c->rcv.src_ip 10.1.23.19) Where: &c->rcv.dst_ip 10.1.23.23 - it is my local kamailio tls socket ip address to make tls connect from c->rcv.dst_port 40123 - it is my local kamailio tls socket port &c->rcv.src_ip 10.1.23.19 - ip of my TLS device to make tls connection to c->rcv.src_port 5061 - port of my TLS device to make tls connection to so if I change line dom = tls_lookup_cfg(cfg, TLS_DOMAIN_CLI, &c->rcv.dst_ip, c->rcv.dst_port, sname, srvid); to dom = tls_lookup_cfg(cfg, TLS_DOMAIN_CLI, &c->rcv.src_ip, c->rcv.src_port, sname, srvid); I got correct client domain selection Oct 26 09:33:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: tls [tls_server.c:233]: tls_complete_init(): Using initial TLS domain TLSc<10.1.23.19:5061> (dom 0x7fd2eefa3d68 ctx 0x7fd2ef7e70a8 sn []) Oct 26 09:33:56 sip1 /usr/sbin/kamailio[20712]: DEBUG: tls [tls_domain.c:703]: sr_ssl_ctx_info_callback(): SSL handshake started Can you look at this code?

Terminating PCSCF unresolvable request URI (Kamailio IMS Websockets)
by Serhat Guler 01 Nov '16

01 Nov '16

Dear all, I am trying to make a call between 2 webrtc clients(sipml5) using my kamailio IMS setup. The invite request fails at the terminating PCSCF with error code "Status: 478 Unresolvable destination (478/TM)". I have traced the packages and saw that the package that arrives at the terminating PCSCF has an unresolvable request URI due to the websocket connection. The package being sent from terminating ICSCF to SCSCF has the "Request-URI: sip:bob@net1.test" The package from terminating SCSCF to terminating PCSCF has the "Request-URI: sip:bob@df7jal23ls0d.invalid;rtcweb-breaker=yes;transport=ws" I guess the terminating SCSCF replaces the request URI with the one it stored during the registration process, but the terminating PCSCF cannot resolve the host name&port number; therefore, it reports back "Unresolvable destination". Is that really the case happening in here ? How can I get over this problem ? Any ideas are welcome. Cheers, Serhat

Store and add custom variables for sip registrations
by Markus Bönke 01 Nov '16

01 Nov '16

Hallo all, we want to use kamailio as registrar server in front of freeswitch. When a user registers we need to lookup and store some user variables. To every INVITE that is received from a registered user we want to add the variables as x sip headers before we relay them to freeswitch. The question is what is the best way to implement this? We tried to store the variables in a htable on register and then lookup and attach the variables on every INVITE from there. Is this the correct approach, one issue we see is that htable is not writing new inserts directly to the database. I’ve also seen that there is a table location_atts in the kamailio db which looks like that it is intended to store custom key value pairs for registrations, but the seems to be no module which writes to that table, or is there one? Thanks for any help or suggestions Markus

Hi! I’m trying to implement scheme much like Federico Cabiddu is described here https://www.youtube.com/watch?v=4XIrR9bwUkM Done a bit modification to his script, cause it’s not fully correct on 4.4 version So, parts of config looks like …. route[REGISTRAR] { … if (!save("location")) { sl_reply_error(); } else { route(PUSHJOIN); } exit; …. } route[LOCATION] { if (!lookup("location")) { …… if (is_method("INVITE")) { send_reply("100", "Trying"); route(SUSPEND); } } else { if (is_method("INVITE")) { if (t_newtran()) { ts_store("sip:$tU@$fd"); } $sht(vtp=>stored::$rU) = 1; } } route(RELAY); } ….. route[SUSPEND] { if(!t_suspend()) { send_reply("501", "Unknown destination"); exit; } $sht(vtp=>join::$rU) = "" + $T(id_index) + ":" + $T(id_label); } # append branches or resume the transaction route[PUSHJOIN] { … #if was suspended - recover, if not - ts_append ….. ts_append(«location", "sip:$tU@$fd"); return; … t_continue("$var(id_index)", "$var(id_label)", "INVRESUME"); } # lookup and relay after resuming transaction route[INVRESUME] { lookup("location"); t_relay(); ts_store("sip:$tU@$fd"); $sht(vtp=>stored::$rU) = 1; } Branches on ts_store are saved in format (sip:username@domain) and also in this format they are added on ts_append. All regarding to routes working ok, except on ts_append I got ERROR: tm [t_append_branches.c:168]: t_append_branches(): ERROR: t_append_branch: failure to add branches (-1) Also, it’s a mixed environment, like wss + udp + tcp. Any idea why? Thanks. -- Best regards, Igor
