BLF state on register
by Loic Chabert 28 Aug '15

28 Aug '15

Hello everyone, I'm trying to reproduce BLF's asterisk fonctionnality with kamailio. With asterisk, on register, NOTIFY message has been sent to all suscribed users. So LED became green. How can i reproduce this function ? I have try to execute a "pua_set_publish()" on register route, but it's not work. My led stay "black", and no notify message has been sent. I have loaded presence, presence_xml, presence_mwi, presence_dialoginfo, pua, pua_dialoginfo, pua_usrloc. Any other module needed ? Thanks, Regards.

In that test rtp was going through the rtpproxy server, Then I configured jssip to test webrtc in this setup, call is connected I can communicate through the extensions both video and voice only in LAN. IN different networks call is connected but, voice is not hear (rtp not working). Kindly help me to configure this web rtc with kamailio. -- Best Regards.. Achintha

multiple proxies
by Bruce Lefko 27 Aug '15

27 Aug '15

If I want to have multiple kamailio proxies in front of multiple media servers, can I balance them using plain old DNS behind a domain name? If I wanted a specific proxy to be notified about an entire SIP dialog I could set the record route to use the public IP of the proxy that received the initial INVITE. Could I leverage something like route53 tcp healthchecks to know if I should be failing over to another proxy?

by José Seabra 27 Aug '15

27 Aug '15

Hello all, I would like to test my presence server using db_mongodb as database server instead of using mysql, but i don't find any documentation explaining how i can configure mongodb database(data structure) for presence or even for the other kamailio modules. Can someone guide me in this setup? Best Regards -- Cumprimentos José Seabra

Confusion about various TCP expiry and lifetime parameters
by M S 27 Aug '15

27 Aug '15

Hi, We have a bit of confusion regarding tcp_connecton_timeout core parameter. The documentation says, -- Lifetime in seconds for TCP sessions. TCP sessions which are inactive for longer than *tcp_connection_lifetime* will be closed by Kamailio. -- However we observe a strange behaviour. 1. The connection is NOT closed by Kamailio unless we additionally set "close_expired_tcp" parameter in usrloc module, 2. Secondly, if we set this parameter to a smaller value say 70 seconds while sip register expiry is 600 seconds (and close_expired_tcp parameter enabled in usrloc module), the connection still remains active (tested after keeping it idle for 120 seconds then sending a sip request on this connection, we expected the request to fail but it does not fails). 3. if we set this parameter to greater then sip register value, e.g. 610 seconds and set close_expired_tcp parameter in usrloc, then we observe disconnect after about 8-10 minutes. Whereas we expect it to continue since user is re-registering every 600 seconds. Can you guys explain why this is happening? What keeps a tcp connection active or makes it inactive? We are using websockets (which use TCP at lower layer) and we observe there is no websocket frame sent or received over the tcp connection, yet it remain active after tcp_connection_lifetime in case 2 above and becomes inactive in case 3. We are using Kamailio v4.3.1 SVN Rev. 4717b5 on Debian Wheezy 32bit OS. Please suggest. Thank you.

IMS Kamailio "477 Unfortunately error on sending to next hop occurred" code sent by the PCSCF
by Victor Huertas Garcia 26 Aug '15

26 Aug '15

Hello everybody, I have tried to perform a call between alice and bob (both registered in the same SCSCF and from the same PCSCF). The INVITE goes all the way as it is supposed: Alice-->PCSCF-->SBC-->SCSCF-->ICSCF-->SCSCF-->SBC-->PCSCF. But when it reaches PCSCF on Network to User direction, this SIP proxy answers with a "477 Unfortunately error on sending to next hop occurred" code just after an exchange with the RTP Proxy (Offer-Answer). At kamailio.cfg (which it is not change from the default config) this exchange is done under Route[RTPRPROXY] in the function: rtpengine_manage("trust-address replace-origin replace-session-connection ICE=remove"); Does anybody know why is complaining (see below) about the server on localhost while it is not configured so? Here you can find the logs from PCSCF: Aug 23 15:10:06 ims rtpengine[556]: [3D504184-55D9D43E00072478-7E0DE700] Received command 'offer' from 192.168.0.108:57522Aug 23 15:10:06 ims rtpengine[556]: [3D504184-55D9D43E00072478-7E0DE700] Creating new callAug 23 15:10:06 ims rtpengine[556]: [3D504184-55D9D43E00072478-7E0DE700] Replying to 'offer' from 192.168.0.108:57522Aug 23 15:10:06 ims /usr/sbin/kamailio[3313]: ERROR: *** cfgtrace:request_route=[RTPPROXY] c=[/etc/kamailio/pcscf/kamailio.cfg] l=813 a=2 n=returnAug 23 15:10:06 ims /usr/sbin/kamailio[3313]: ERROR: *** cfgtrace:request_route=[Term_Initial] c=[/etc/kamailio/pcscf/kamailio.cfg] l=1196 a=24 n=t_relayAug 23 15:10:06 ims /usr/sbin/kamailio[3313]: ERROR: <core> [udp_server.c:550]: udp_send(): sendto(sock,0x7f480e27ed70,1358,0,192.168.0.105:49284,16): Invalid argument(22)Aug 23 15:10:06 ims /usr/sbin/kamailio[3313]: CRITICAL: <core> [udp_server.c:555]: udp_send(): invalid sendtoparameters#012one possible reason is the server is bound to localhost and#012attempts to send to the net Here you can find the configuration from RTP proxy (/etc/default/ngcp-rtpengine-daemon) and you can see that I am not listening the localhost port at "INTERFACES": RUN_RTPENGINE=yes LISTEN_TCP=25060LISTEN_UDP=12222LISTEN_NG=22222LISTEN_CLI=9900INTERFACES="192.168.0.108"TIMEOUT=60SILENT_TIMEOUT=3600PIDFILE=/var/run/ngcp-rtpengine-daemon.pidFORK=yes# TOS=184TABLE=0# NO_FALLBACK=yes# PORT_MIN=30000# PORT_MAX=50000# REDIS=127.0.0.1:6379# REDIS_DB=1# B2B_URL=http://127.0.0.1:8090/# LOG_LEVEL=6# LOG_FACILITY=daemon# LOG_FACILITY_CDR=daemon# LOG_FACILITY_RTCP=daemon# NUM_THREADS=5# DELETE_DELAY=30# GRAPHITE=9006# GRAPHITE_INTERVAL=60# GRAPHITE_PREFIX=myownprefix# MAX_SESSIONS=5000 And finally the pcscf.cfg: # SIP / UDPlisten=udp:eth0:4060#listen=udp:127.0.0.1:4070listen=udp:127.0.0.1:4060# SIP / TCP (Monitoring)#listen=tcp:127.0.0.1:4060# SIP / TCP/TLS#listen=tls:109.239.57.200:5061# SIP / Websocket #!define MY_WS_PORT 80 listen=tcp:eth0:MY_WS_PORT # SIP / Websocket/TLS#!define MY_WSS_PORT 443#listen=tls:109.239.57.200:MY_WSS_PORT #alias=pcscf-1.imscore.orgalias=pcscf.home-domain.net#alias=proxy.imscore.org#alias=tls:"wss-proxy.imscore.org":443 # Port, where we listen to Traffic#!define PORT 4060 # NUEVO Workshop!#!define SBCPORT 5080#!define PCSCF_URL "sip:pcscf.home-domain.net"#!define TCP_PROCESSES 32 #!subst "/NETWORKNAME/home-domain.net/"#!subst "/HOSTNAME/pcscf.home-domain.net/"#!define HOSTNAME_IP pcscf.home-domain.net#!define HOSTNAME_ESC "pcscf\.home-domain\.net" # SIP-Address of capturing node, if not set, capturing is disabled.##!define CAPTURE_NODE "sip:10.1.8.55" # Allowed IPs for XML-RPC-Queries#!define XMLRPC_WHITELIST_1 "127.0.0.1"##!define XMLRPC_WHITELIST_2 "127.0.0.1"##!define XMLRPC_WHITELIST_3 "127.0.0.1" # Databases:#!define DB_URL "mysql://pcscf:heslo@127.0.0.1/pcscf"##!define DB_URL2 "con2=>mysql://pcscf:heslo@127.0.0.1/pcscf"##!define DB_URL "con1=>mysql://pcscf:heslo@192.168.5.1/pcscf"##!define DB_URL2 "con2=>mysql://pcscf:heslo@10.1.27.217/pcscf" #!

Kamailio dead after INVITE from SIPDROID
by Kowalski Piotr 3 - Hurt 26 Aug '15

Hello Community. We have openIMS nodes in our lab. We have Kamailio 4.0 based solution. I registered SIPDROID client (iptel) on Android and JITSI on WINDOWS. When I call from SIPDROID to JITSI following happens: SIP DROID - iptel - client - registration ok, but INVITE attempt towards JITSI (and other clients) does what's below: HSS (every 30 seconds): [root@hss1 kowalp00]# 2015-08-25 12:16:55,468 WARN de.fhg.fokus.diameter.DiameterPeer.transport.Communicator - run Read 3021 before Exception. 2015-08-25 12:16:56,980 ERROR de.fhg.fokus.diameter.DiameterPeer.peer.StateMachine - I_Snd_Conn_Req StateMachine: Peer scscf1.hss.ims.test.pl:3868 not responding to connection attempt 2015-08-25 12:17:26,985 ERROR de.fhg.fokus.diameter.DiameterPeer.peer.StateMachine - I_Snd_Conn_Req StateMachine: Peer scscf1.hss.ims.test.pl:3868 not responding to connection attempt SCSCF: Aug 25 12:24:18 scscf1 /usr/sbin/kamailio[8879]: INFO: <core> [main.c:854]: INFO: signal 15 received Aug 25 12:24:18 scscf1 /usr/sbin/kamailio[8865]: INFO: <core> [main.c:854]: INFO: signal 15 received Aug 25 12:24:18 scscf1 /usr/sbin/kamailio[8803]: INFO: snmpstats [snmpstats.c:410]: The SNMPStats module got the kill signal Aug 25 12:24:18 scscf1 /usr/sbin/kamailio[8803]: INFO: snmpstats [snmpstats.c:414]: Shutting down the AgentX Sub-Agent!
