ACK not accepted

Hi, I am having a problem with some inbound calls that all have the below behavior. My setup has: Carrier(UDP) -> (UDP)Kamailio1(UDP) -> (UDP)Kamailio2(TLS) -> (TLS)UAC Kamailio1 has Topos Module. UAC is behind NAT with LAN IP 192.168.1.105 and Public 200.200.200.30 Carrier IP 50.50.50.19, Kamailio1 IP 100.100.100.243, Kamailio2 IP 100.100.100.210 The Carrier sends in a new call and the call is answered from the UAC with 200 OK SDP. Carrier sends ACK and it looks like it reaches the UAC but, UAC still resends several times 200 OK and carrier sends server ACK that arrives or not ??? to UAC until finally UAC sends a BYE. On the SIP flow you can see that Kamailio2 sends the ACK to 192.168.1.105 and not to 200.200.200.30. Is this ok?? Another thing to mention is that Kamailio2 that has the UAC connected via TLS, can be used fine from the UAC to make an outbound call following the reverse path, but on the inbound we have the below. Any help will be much appreciated, ACK from Kamailio2 100.100.100.210 to UAC Session Initiation Protocol (ACK) Request-Line: ACK sip:btpsh-f3-6153392a-5fa-5@192.168.1.105:5061;transport=TLS SIP/2.0

Querying presence state from config file
by Igor Olhovskiy 01 Oct '21

01 Oct '21

Hello! Is there any method of querying presence (dialog) state for particular endpoint from config file other than that direct query to presence tables in database? Idea is to reflect server-side DND state as "confirmed" (talking) , so I need to skip certain PUBLISH messages not to reset this state. -- Best regards, Igor

kamailio 4.4 + RTPPROXY - virtualbox - setup - callee or caller sends INVITE during the conversation and at REGISTER EXPIRES stop the connection
by Youssef Boujraf 01 Oct '21

01 Oct '21

Dear Thanks for your quick reply and sorry for spamming your mailbox. I am very confused about the setup of kamailio.cfg and rtpproxy. I have an existing kamailio 4.4 - rtpproxy running and I get the config files from both and setup the new vm. Just private connection works but the idea is to have connection from outside too. I am sure there is a mismatch with public ip, natting and/or setup of the vm hosts file. - architecture: *- 1x virtualbox* + 1x vm with bridge mode for network (get private ip address from the router). I suppose this is the PRIVATE_IP *+ 1x desktop (windows)* hosting a sipphone here Microsip ( https://www.microsip.org/) *- 1x modem/router* from the telecom provider - bbox-3V+ from PROXIMUS + forced in DMZ host the Kamailio server PRIVATE_IP [image: 211001 - kamailio architecture and settings.png] - the hosts file from Kamailio + rtpproxy is ( Maybe something is wrong or missing) /etc/hosts 127.0.0.1 localhost > 127.0.1.1 sipsecure.by-systems.be sipsecure > 192.168.1.19 sipsecure.by-systems.be sipsecure > xxx.XXX.xxx.XXX sipsecure.by-systems.be sipsecure > # The following lines are desirable for IPv6 capable hosts > ::1 localhost ip6-localhost ip6-loopback > ff02::1 ip6-allnodes > ff02::2 ip6-allrouters > */etc/kamailio/kamailio.cfg* kamailio.config > #!define PUBLIC_IP "xxx.xxx.xxx.xxx" > #!define PRIVATE_IP "192.168.1.19" > #!define PRIVATE_NET "192.168.1.0/24“ > > #!ifdef WITH_NAT > > # ----- rtpproxy params ----- > > modparam("rtpproxy", "rtpproxy_sock", "udp:PRIVATE_IP:7722") > > > # ----- nathelper params ----- > > modparam("nathelper", "natping_interval", 30) > > modparam("nathelper", "ping_nated_only", 1) > > modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) > > modparam("nathelper", "sipping_from", "sip:pinger@kamailio.org") > *Etc/default/rtpproxy* PRIVATE_IP=192.168.1.19 > > PUBLIC_IP=xxx.xxx.xxx.xxx > > rtpport_min= 10000 > > rtpport_max=20000 > > syslog=DBUG:LOG_LOCAL5 > > #Defaults for rtpproxy > #The control socket. > #CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock" > #To listen on an UDP socket, uncomment this line: > #CONTROL_SOCK=udp:127.0.0.1:7722 > #Additional options that are passed to the daemon. > EXTRA_OPTS="-l $PRIVATE_IP/$PUBLIC_IP ="-s $PRIVATE_IP:7222 -m $ > rtpport_min -M $rtpport_max -d $syslog"` > - *Misconfiguring the VM* That means do I need to use setup 1 or 2 or another 1. 2x NIC interfaces (one with private ip, second from dmz ip + NAT1:1 public ip) 2. 1x NIC interface (one private ip and natted 1:1 with public address) - *test* 1. *use case 1 : *connect two (2x) sipphone from private network (included kamailio) = OK 2. *use case 2 :* connect one (1x) codec from private ip and one (1x) codec from public network (like mobile) = = issue - disconnect after 30 s (register expires) start a conversation with audio but the caller or the callee continues to send and INVITE message. 3. *use case 3 :* connect two (2x) sipphone from public network = issue - disconnect after 30 s (register expires) start a conversation with audio but the caller or the callee continue to send an INVITE message.

RTPEngine + Kamailio state question
by Alex Balashov 30 Sep '21

30 Sep '21

Hi, Sorry if I missed any developments on this, but: Kamailio does keep a runtime association of Call-ID+Ftag => RTPEngine instance, which is significant if an RTPEngine set with multiple members is used, or if a non-default set is used for a given call. When Kamailio is restarted, this runtime association goes away, so any subsequent offer/answer cycles or any other commands will (maybe) go to the wrong RTPEngine and/or the wrong set. Last time I checked a few years ago, there was no way to persist this association across restarts. Has this changed?

Sipwise SEMS

Hello guys, I know SEMS can provide conference, voicemail, and other services. In theory it’s also a B2BUA. Could I use a python script to provide a simple routing service? I.e.: receive an invite and send it somewhere else based on some routing logic? Thanks all David -- Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

using LDAP as database ?
by Volker Denneberg 28 Sep '21

28 Sep '21

Hi, I am searching for a setup where phones register at a central kamailio and kamailio shares these contact infos with multiple asterisks. So they all need to share a database. For redundancy reasons, the database should work across 2 datacenters. As far as 1 understood there are some options * use mysql - good chances to find example code, Siremis API, seems to be the standard solution * use redis - more performant than mysql * use ldap - good chances to integrate with existing IT management but most difficult to configure Maybe I missed a better approach? Kamailio's ldap driver (http://www.kamailio.net/docs/modules/5.3.x/modules/db2_ldap.html) seems to be from 2008 - is it still recommended ? Kind regards, Volker

siptrace & topos modules on 5.3
by Angelo Sipper 24 Sep '21

24 Sep '21

Hi, We are using kamailio 5.3 latest version with the topos module. We have added Homer 7 latest version to consolidate traces from all kamailios and we have enabled siptrace module on kamailio to send data to homer. What we have seen up today is that traces on homer have sip headers before topos changes. So if I look at the same call on sngrep on the kamailio machine, I see the correct topos changed headers. If I check the same call on Homer I see headers without topos changes. Also we get duplicate headers on ACKs on homer. I was wondering what we have done wrong in the config and we have these results on homer. Any help will be much appreciated! Our config has: ===========- #!substdef "!MY_HOMER_CAPTURE!sip:MY_HOMER_IP_ADDR:MY_HOMER_PORT!g" #!substdef "!MY_LOCAL_SENDSOCK!sip:MY_KAMAILIO_IP:MY_LOCAL_SEND_PORT!g" loadmodule "topos.so" loadmodule "siptrace.so" modparam("siptrace", "force_send_sock", "MY_LOCAL_SENDSOCK") modparam("siptrace", "duplicate_uri", "MY_HOMER_CAPTURE") modparam("siptrace", "hep_mode_on", 1) modparam("siptrace", "hep_version", 3) modparam("siptrace", "trace_to_database", 0) modparam("siptrace", "trace_on", 1) modparam("siptrace", "trace_mode", 0) modparam("siptrace", "hep_capture_id", NODE_ID) modparam("topos", "db_url", DBURL) modparam("topos", "mask_callid", 0) modparam("topos", "sanity_checks", 0) modparam("topos", "branch_expire", 130) # 3 Min modparam("topos", "dialog_expire", 10800) # 3 Hours modparam("topos", "clean_interval", 60) modparam("topos", "event_mode", 3) request_route { sip_trace_mode("t"); ........ } onsend_route { if (is_method("ACK")) { sip_trace(); } } ============== Thank you!

PRACK with UDP to TCP translation send over wrong protocol
by Angelo Sipper 24 Sep '21

24 Sep '21

Hello, We have the following setup and I am having trouble passing the PRACK with correct protocol to the provider. UAC (OverTLS) ->(UDP)Kamailio1 (UDP)-> (UDP)Kamailio2 (TCP)-> (TCP)Provider UAC : 10.2.1.160 NATED to 100.100.100.61 <http://50.50.50.50:5065/> (TLS) Kamailio1 Sockets: 50.50.50.210:5061 <http://170.170.170.210:5061/> (TLS), 50.50.50.210:5060 <http://170.170.170.210:5060/> (UDP) Kamailio2 Sockets: 50.50.50.182:5060 <http://170.170.170.170:5060/> (UDP) 50.50.50.182:5080 <http://170.170.170.170:5060/> (TCP) Provider: 200.200.200.209:5060 <http://200.200.200.193:5060/> (TCP) We use dispatcher on Kamailio1 & Kamailio2 The invite goes fine from UCA up to the provider and the provider responses arrive to UAC fine. The PRACK from UAC to kamailio1 goes fine to Kamaili02 but, Kamailio2 uses the UDP socket to send to the provider so the PRACK does not arrive to the provider and the call is canceled. If the provider is on UDP everything works fine. Below I have the trace. What should I look for in the config to resolve this wrong protocol/socket on the PRACK?

Releasing Kamailio 5.3.9
by Henning Westerholt 23 Sep '21

23 Sep '21

Hello, I am planning to release in two weeks (likely on Wednesday 7th October) the next minor version out of branch 5.3, version 5.3.9. Backports of fixed issues from other stable branches will be integrated as usual. If you are aware of new issues which were not yet reported on the issue tracker or are missing back-ports, report them. Please note that this will be the last minor release created from the 5.3.x stable branch. The stable branches are usually maintained from the Kamailio development team for a period of two years. The other two stable branches of Kamailio will still be maintained (5.4.x and 5.5.x). Cheers, Henning -- Henning Westerholt - https://skalatan.de/blog/ Kamailio services - https://gilawa.com<https://gilawa.com/>
