Question about a Slow timer process.

by Володимир Іванець

Hello everyone! I'm running Kamailio 5.6.2 and having a potential problem on one of the systems. The Slow timer process slowly consumes more and more of its PKG memory. I did not allow it to use all memory by restartink Kamailio during afterhours so I'm not sure what the consequences might be. I'm suspecting that this could be caused by my configuration but not sure how exactly. Can anyone please tell me how the Slow timer process can be debugged? Is it possible to see what it is storing in the memory and what data is piling up? Thanks a lot! Regarts, Volodymyr Ivanets.

uac_replace_to() without RR params

by Duarte Rocha

Hello all, I'm currently working on a proxy where I need to change To and From headers in order to normalize the numbers to +E164. I would like to be able to restore using and $avp() or $dlg_var() and without writing parameters on the Record-Route headers. I've tried to use restore_mode in auto mode and restore_dlg parameter with value 1 but still got the parameters on the inserted Record-Route. I've tried manual mode and using the configured $avp() to restore, but the parameters still got written on the Request-URI. I thought of using restore_mode with value "none" saving original values in an $avvp() and doing the replace, however, uac_replace() on Request Route or branch routes. That way i can't replace the values of To and From in the replies. That being said, my questions are : - Is there a way to use manual or auto mode without writing info on the Record-Route and only using $avp() ? - Is there a way to make changes on the To and From header on replies? Thanks in advance, Best Regards, Duarte Rocha

Unnecessary/Invalid AVPs in CCR message over Ro Interface

by s.ghahremannejad＠gmail.com

**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

Hello, Running ”kamcmd permissions.trustedReload” it instantly returns “Reload OK” but I cannot repeat the reload for about 8 seconds. This is the same for dialplan.reload and dispatcher.reload. root@superman.local:/# kamcmd permissions.trustedReload Reload OK root@superman.local:/# kamcmd permissions.trustedReload error: 500 - ongoing reload root@superman.local:/# kamcmd permissions.trustedReload error: 500 - ongoing reload There are scenarios where I might need to reload the permission table multiple times within this 8 second window. Is this some kind of intended block or is something at fault? modparam("db_mysql", "ping_interval", 60) modparam("db_mysql", "timeout_interval", 4) modparam("db_mysql", "auto_reconnect", 1) modparam("db_mysql", "opt_ssl_mode", 0) modparam("permissions", "db_url", "mysql://kamailio:xxxxx@aws-rds-database /kamailio") version: kamailio 5.7.1 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 10.2.1 /M

by bikq＠163.com

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

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
