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

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.
