Unnecessary/Invalid AVPs in CCR message over Ro Interface
by s.ghahremannejad＠gmail.com 06 Sep '23

06 Sep '23

**Issue Description** I'm encountering an issue with my Kamailio configuration related to the inclusion of the "Accounting-Record-Type" (480) and "Accounting-Record-Number" (485) AVPs in Credit-Control Request (CCR) messages sent from the S-CSCF to the OCS. **Issue Details** - **Problem**: The "Accounting-Record-Type" and "Accounting-Record-Number" AVPs are being added to CCR messages generated by my Kamailio instance. - **Expected Behavior**: According to modern Diameter and 3GPP standards (e.g., RFC 4006 and TS 32.299), these AVPs should not be included in CCR messages. **Configuration Details** - **Kamailio Version**: 5.3.0 - **SigScale OCS Version**: 3.2.9 Note that I have redacted some specific information for confidentiality reasons. The actual values are placed in my Kamailio main configuration file (`kamailio.cfg`) and Diameter-specific configuration files (where applicable). Kamailio.cfg: modparam("ims_charging", "db_url", DB_URL) modparam("ims_charging", "db_mode", 1) modparam("ims_charging", "origin_host", HOSTNAME); modparam("ims_charging", "origin_realm", NETWORKNAME); modparam("ims_charging", "destination_host", DESTINATION_HOST); modparam("ims_charging", "destination_realm", DESTINATION_REALM); modparam("ims_charging","service_context_id_root", RO_ROOT); modparam("ims_charging","service_context_id_ext", RO_EXT); modparam("ims_charging","service_context_id_mnc", MNC); modparam("ims_charging","service_context_id_mcc", MCC); modparam("ims_charging","interim_update_credits",30); modparam("ims_charging","timer_buffer",5); SCSCF.xml: <?xml version="1.0" encoding="UTF-8"?> <DiameterPeer FQDN="scscf.mncXXX.mccXXX.3gppnetwork.org" Realm="ims.mncXXX.mccXXX.3gppnetwork.org" Vendor_Id="10415" Product_Name="CDiameterPeer" AcceptUnknownPeers="1" DropUnknownOnDisconnect="1" Tc="30" Workers="16" QueueLength="32" TransactionTimeout="5" SessionsHashSize="128" DefaultAuthSessionTimeout="3600" MaxAuthSessionTimeout="3600" > <Peer FQDN="diameter" Realm="ims.mncXXX.mccXXX.3gppnetwork.org" port="3868"/> <Peer FQDN="192.168.2.31" Realm="ocs.ims.mncXXX.mccXXX.3gppnetwork.org" port="3868"/> <Acceptor port="3868" bind="eth0"/> <Auth id="16777216" vendor="10415"/> <Auth id="16777216" vendor="4491"/> <Auth id="16777216" vendor="13019"/> <Auth id="16777216" vendor="0"/> <Auth id="4" vendor="10415"/>  <Acct id="4" vendor="10415" />  <SupportedVendor vendor="10415" /> <Realm name="ocs.ims.mncXXX.mccXXX.3gppnetwork.org"> <Route FQDN="192.168.2.31" metric="10"/> </Realm> <DefaultRoute FQDN="diameter" metric="10"/> </DiameterPeer> I am using SigScale OCS as my Online Charging System.

Possible Configurations: Are there specific configurations or modules in Kamailio that might cause the inclusion of non-standard AVPs in CCR messages? 2. IMS Ro Interface Behavior: Does anyone have experience with IMS Ro interface behavior using Kamailio that could shed light on this? If you have any guidance, suggestions, or solutions to help me troubleshoot and resolve this problem, please share them. Thank you for your assistance.

kamcmd reload is slow or blocking additional reloads
by Martin Nyström 06 Sep '23

Hello, Running ”kamcmd permissions.trustedReload” it instantly returns “Reload OK” but I cannot repeat the reload for about 8 seconds.

目前进行一通呼叫后，在acc表中可以看到Invite、ack及bye的记录详情并带有时间，acc_cdrs表中只有start_time及end_time,是对应invite和bye的。现在我想在acc_cdrs中增加ack的时间我该如何去做呢？有没有大佬能解答一下？万分感谢！！！

Configuring package memory
by Ivan Ribakov 05 Sep '23

05 Sep '23

Is there any specific reason why shared memory can be configured via the config files ("shm_mem_size") AND CLI flags ("-m") but package memory can only be set via CLI flags ("-M")? Did no one ever came across the need to configure the package memory limit so far, or is there another way to achieve it without using the CLI flag? -- Ivan Ribakov Software Engineer www.zaleos.net

Re: Kamailio stops processing UDP on one interface

Bastian, According to mine stats all seems ok... # kamctl stats shmem { "jsonrpc": "2.0", "result": [ "shmem:fragments = 330", "shmem:free_size = 1889418024", "shmem:max_used_size = 258962624", "shmem:real_used_size = 258065624", "shmem:total_size = 2147483648", "shmem:used_size = 248809096" ], "id": 212042 } pkg.stats also not showing any signs of exhausting. For me what is working is server can send packets, but not receive em back even. And it's happening only on 1 interface.

Install Kamailio 5.3
by Daniel Oliveira Hilário 30 Aug '23

30 Aug '23

Hi people, I installed Kamailio 5.3 on Ubuntu Server 22 LTS, but I am not able to resolve several PHP errors that occur when I try to open the website http://localhost/siremis/. Which Linux distro and version is best suited for installation? Is Kamailio version 5.3 operational or is it better to use version 4.4? Att., Daniel Hilário INFRACOM/UFRGS 51 3308 4801

Kamailio stops processing UDP on one interface
by Ihor Olkhovskyi 30 Aug '23

30 Aug '23

Hello, I've faced a bit strange issue, but a bit of preface. I have Kamailio as a proxy (TLS/WS <-> UDP) and second Kamailio as a presence server. At some point presence server accepts around 5K PUBLISH within 1 minute and sending around the same amount of NOTIFY to proxy Kamailio. Proxy is "transforming" protocol to TLS, but at sime point I'm starting to get these type of errors tm [../../core/forward.h:292]: msg_send_buffer(): tcp_send failed tm [t_fwd.c:1588]: t_send_branch(): sending request on branch 0 failed <script>: [RELAY] Relay to <sip:X.X.X.X:51571;transport=tls> failed! tm [../../core/forward.h:292]: msg_send_buffer(): tcp_send failed tm [t_fwd.c:1588]: t_send_branch(): sending request on branch 0 failed Some of those messages are 100% valid as client can go away or so. Some are not, cause I'm sure client is alive and connected. But the problem comes later. At some moment proxy Kamailio just stops accept UDP traffic on this interface (where it also accepts all NOTIFY's), at the start of the "stopping accepting" Kamailio sends OPTIONS via DISPATCHER but not able to receive 200 OK. Over TLS on the same interface all is ok. On other (loopback) interface UDP is being processed fine, so I don't suspert some limit on open files here. Only restart of Kamailio proxy process helps in this case. I've tuned net.core.rmem_max and net.core.rmem_default to 25 Mb, so in theory buffer should not be the case. Is there some internal "interface buffer" in Kamailio that is not freed upon failure send or maybe I've missed somethig? Kamailio 5.6.4 fork=yes children=12 tcp_children=12 enable_tls=yes tcp_accept_no_cl=yes tcp_max_connections=63536 tls_max_connections=63536 tcp_accept_aliases=no tcp_async=yes tcp_connect_timeout=10 tcp_conn_wq_max=63536 tcp_crlf_ping=yes tcp_delayed_ack=yes tcp_fd_cache=yes tcp_keepalive=yes tcp_keepcnt=3 tcp_keepidle=30 tcp_keepintvl=10 tcp_linger2=30 tcp_rd_buf_size=80000 tcp_send_timeout=10 tcp_wq_blk_size=2100 tcp_wq_max=10485760 open_files_limit=63536 Sysctl # To increase the amount of memory available for socket input/output queues net.ipv4.tcp_rmem = 4096 25165824 25165824 net.core.rmem_max = 25165824 net.core.rmem_default = 25165824 net.ipv4.tcp_wmem = 4096 65536 25165824 net.core.wmem_max = 25165824 net.core.wmem_default = 65536 net.core.optmem_max = 25165824 # To limit the maximum number of requests queued to a listen socket net.core.somaxconn = 128 # Tells TCP to instead make decisions that would prefer lower latency. net.ipv4.tcp_low_latency=1 # Optional (it will increase performance) net.core.netdev_max_backlog = 1000 net.ipv4.tcp_max_syn_backlog = 128 # Flush the routing table to make changes happen instantly. net.ipv4.route.flush=1 -- Best regards, Ihor (Igor)

How to forward 480
by Anthony Blandin 29 Aug '23

29 Aug '23

Hello, I have a Kamailio SBC connected to another foreign SBC and to a media server. In case of non response, Kamailio SBC receives a 480 Temporarily not available from the foreign SBC and I need to forward this 480 to my media server but I don't see how to do that. The 480 arrives in the onreply_route. If I use then a failure_route, it resends the initial INVITE and not the 480. Is there a way to do that? Thanks for your help. Anthony Blandin
