Hi everybody, I'm just testing Kamailio 5.4.1 with dialog replication over DMQ. This seems to work very good. Dialogs are replicated without problems. When I'm restarting one node I would have expected, that all dialogs are synced again, just like in dmq_usrloc. But this does not happen. After a restart the nodes dialog-list is empty. Did I miss somethin? Is there a special parameter that I have to set?

Is Min-SE check broken?

by harneet singh

Hi All, I am facing an issue in understanding how the min_se should be working in kamailio. As per the SST documentation, it seems like if the min_se is configured as 500, then any value of Session-Expires OR MIN-SE if lower than 500, can be responded to by a 422. However, I strangely see the reverse happening. To investigate further, I looked in to the ki_sst_check_min() code in the master, and these seems like a potential issue. Ref Code: Inside ki_sst_check_min(), there is an if condition like below: if (sst_min_se < MIN(minse, se.interval)) { However, shouldn't it be the other way around? ie if (sst_min_se > MIN(minse, se.interval)) { because we need to send 422 if the received value(in INVITE etc) is smaller than the sst configure min_se value? I also found a different documentation, at https://git.sgu.ru/oldssu/ex-opensips/blob/cb9df8d59dbb254a9d862569fd5d11f6… where the check is as below? if (sst_min_se > MIN(minse, se.interval)) { Can someone confirm if this is broken, or my understanding is incorrect?

Config works fine with mysql as topos backend. So the bug is restricted to topos-redis.

enable topology hiding on one side or dynamic ip in topoh module Contact and Via Header

by Patrick Karton

Hello , im using kamailio with two interfaces external and internal. i need a way either to : * enable topoh hiding only when outgoing interface is external ( mask contact and Via ip only when ougoing interface is external * or if it is not possible to enable it only in one direction.i want to know how to configure dynamic(for example in xavp or avp) ip to put in Contact and Via when topoh is enabled. i see that the 'mask_ip' parameter of topoh module is a string. so we can not set a dynamic value here unfortunately. Thanks

kamcmd autocompletion

by Antoine DEBARRE

Hi, I just installed kamailio v5.5 via deb.kamailio.org packages (debian 11). Seems that kamcmd autocompletion doesn't work at all. It is OK for v5.4 via official debian packages (packages.debian.org/bullseye/kamailio) Best regards, -- <https://app.livestorm.co/comdata-group/metaverse-what-will-cx-look-like-in-…>

Recommended openSSL version

by Igor Olhovskiy

Hello! Due to I still experience irregular Kamailio 5.4 crashes (like 1/month) related to SSL (using websockets and SIPS) I'm wondering, could openSSL upgrade change the situation? As of now in CentOS 7 I have 1.0.2k version. Does anyone have experience to fix crash-related to TLS problems with openSSL upgrade? Or maye some tuneup of TCP parameters can help here?My current setup is quite simple: children=4 enable_tls=yes tcp_accept_no_cl=yes tcp_connection_lifetime=600 tcp_max_connections=998976 # 1000000 - 1024, so we're leaving 1k for system reserve tls_max_connections=998976 Number of clients ~ 200 constantly connected to websocket. -- Best regards, Igor

Siremis JSONRPC problem on Bullseye

by Joseph Goettgens

I am not sure what I have to look for and I didn't change the initial config files (except for the 666 mode for kamailio_rpc.sock). As far as Kamailio is concerned the socket files files do exist: root@deb11srv1-kamailio:/var/www/siremis-5.3.x# ls -l /run/kamailio/ insgesamt 4 srw------- 1 kamailio kamailio 0 7. Jun 11:37 kamailio_ctl -rw-r--r-- 1 kamailio kamailio 5 7. Jun 11:37 kamailio.pid prw-rw---- 1 kamailio kamailio 0 7. Jun 11:37 kamailio_rpc.fifo srw-rw-rw- 1 kamailio kamailio 0 7. Jun 11:37 kamailio_rpc.sock When I look at siremis/log/ERR.log I repeatedly get: '06/07/2022','09:43:29','ERR','ErrorHandler','socket_bind(): unable to bind address [2]: No such file or directory','' This disappears when I put the local file socket in /tmp: <UnixSockLocal name="unixsocklocal" address="/tmp/siremis_rpc.sock" timeout="3.0"/> which was probably done this way in previous versions of Siremis (before systemd private tmp config). In this case I get no error messages, but still no answers (as expected). The next step seems to get UnixSockLocal right.

Kamailio behind NAT

by Алексей Якимкин

Hello, I have kamailio in local network behind NAT. Kamailio have one interface eth1 with ip 10.130.0.23 UserAgent - (internet) - (178.0.0.169)router_with_NAT - (LAN) - kamailio+rtpproxy - pbx I made two listeners: listen=udp:10.130.0.23:5070 #to pbx in lan (I don`t want to put via header with 178.0.0.169) listen=udp:10.130.0.23:5060 advertise 178.0.0.169:5060 #to internet (UserAgent need to get via header with 178.0.0.169 ) mhomed = 1 # I think It not useful for my case UserAgent send Register and Invite to 178.0.0.169:5060, Kamailio get it on udp:10.130.0.23:5060 Kamailio Relay it to udp:10.130.0.23:5070 My pbx get requests from udp:10.130.0.23:5070 with via header 10.130.0.23 Responses to UserAgent go from udp:10.130.0.23:5060 with via 178.0.0.169 In RELAY block: if ($Ru == «udp:10.130.0.23:5070») { #set_send_socket(«udp:10.130.0.23:5060»); $fs = «udp:10.130.0.23:5060»; #force_send_socket(«udp:10.130.0.23:5060»); } else { #set_send_socket(«udp:10.130.0.23:5070»); $fs = «udp:10.130.0.23:5070»; } #$fs = «udp:10.130.0.23:5070»; if (!t_relay()) { sl_reply_error(); } route[REGISTRAR] { if ($rd == "mydomain.ru" || $rd == "mydomain2.ru") { set_send_socket("udp:10.130.0.23:5070"); } } It works for requests from UserAgent to PBX. But INVITE from my pbx to UserAgent goes only through udp:10.130.0.23:5070 , Kamailio realy it to internet from udp:10.130.0.23:5070 I get error in syslog: (pv [pv_branch.c:62]: pv_get_branchx_helper(): error accessing branch [0]) I tried set_send_socket(«udp:10.130.0.23:5070»); and $fs = «udp:10.130.0.23:5070»; Why I can`t relay outgoing requests to internet through another socket? -- Best regards, Alex

ACC CDR accounting

by Oleg Podguyko

HI I’m trying to get CDR function. I would like to have one CDR for whole call at the syslog. I use: …… loadmodule "db_text.so" loadmodule "dialog.so" loadmodule "acc.so" …….. # -----Dialog module ----- modparam("dialog", "db_mode", 0) # -----ACCounting module ----- modparam("acc", "early_media", 0) modparam("acc", "report_cancels", 1) modparam("acc", "log_facility", "LOG_LOCAL1") modparam("acc", "detect_direction", 0) modparam("acc", "log_level", ACC_LOG_LEVEL) modparam("acc", "log_flag", FLAG_ACC_LOG) modparam("acc", "log_missed_flag", FLAG_ACC_LOG_MISSED) modparam("acc", "failed_transaction_flag", FLAG_ACC_LOG_FAILED) modparam("acc", "log_extra", "ip_src=$si;ip_dst=$avp(ip_dst);sip_from=$fU;sip_to=$tU;ruri_user=$rU;spx_rs=$avp(spx_http_rs)") ## TODO modparam("acc", "cdr_enable", 1) modparam("acc", "cdr_enable_log", 1) modparam("acc", "cdr_facility", "LOG_LOCAL1") request_route { if (is_method("INVITE")) { setflag(FLAG_ACC_LOG); setflag(FLAG_ACC_LOG_MISSED); setflag(FLAG_ACC_LOG_FAILED); } At the kamailio.log I see only transaction for INVITE, but I wait for some CDR for all dialog. Whats wrong in my config? -- -- Олег Подгуйко
