Via header force change protocol to TLS?
by Anthony Alba 30 May '24

30 May '24

I have kamailio behind a TLS termination proxy so the sockets are correctly deduced to be TCP. However the clients only talk TLS to the proxy and are confused when the top Via header added by Kamailio is TCP. Is there a way for Kamailio to forcibly pretend its protocol is TLS? Like advertised_address but "advertised_protocol" instead. (With pjsip testing: it has a flag use_tls which ignores TCP from Kamailio and continues to use the persistent TLS transport to proxy. Linphone fails because it tries to honor TCP in Via and is unable to establish TCP transport). BTW I am using t_relay_to_tcp so Kamailio will return traffic to the proxy as TCP even though the contact addresses specify transport=TLS.

Hi, We’re still using kamailio 4.4 but we’ll be migrating to 5.0 soon. Cool so it will be fixed when we migrate !

need help with RTPProxy in bridged mode
by Grant Bagdasarian 04 Apr '20

04 Apr '20

Hello, I'm using RTPproxy for the first time in bridged mode and I can't get kamailio/rtpproxy to rewrite the c parameter to the correct public ip address of kamailio. The setup is as following: Carrier ------[fiber]------ Kamailio ---------[lan]--------- Freeswitch Kamailio is listening on two interfaces: 1) Private: 172.0.0.1 2) Public: 192.168.0.1 (since we have a dedicated fiber with our carrier, this is its public address) Freeswitch is listening on: 1) 172.0.0.2 Carrier is on: 1) 10.0.0.1 I've started an rtpproxy instance on the Kamailio box using: rtpproxy -s udp:127.0.0.1:7721 -u rtpproxy rtpproxy -p /var/run/rtpproxy/rtpproxy.pid -l 192.168.0.1 172.0.0.1 I've played around with rtpproxy_manage() and the various flags (ie, ei), but I can't get kamailio to set the correct public IP when the 200 OK has to be sent back to the carrier. It always sets it to its private address, instead of its public address. I'm using Kamailio 4.2 with sippy/rtpproxy 2.0. Could someone please point me into the right direction? Thanks! Grant

rtpproxy does not response, disable it
by Zodiac 03 Jan '20

03 Jan '20

Dear friends, I am working on a program on Kamailio and rtpengine proxy. I am wondering whether can I set Kamailio and rtpengine daemon on different physical machines. For example, I set Kamailio on a machine with IP address:10.109.247.80, and launch rtpengine daemon on another machine with interface parameter as 10.109.247.90 and ng port 7723. I set parameter in Kamailio.cfg with modparam(“rtpengine”, “rtpengine_sock”, “udp:10.109.247.90:7723”). Unfortunately I got debug message like this: ERROR: rtpengine [rtpengine.c:1710]: send_rtpp_command(): can't send command to a RTP proxy ERROR: rtpengine [rtpengine.c:1746]: send_rtpp_command(): proxy <udp:10.109.247.90:7723> does not respond, disable it ERROR: rtpengine [rtpengine.c:1616]: rtpp_test(): proxy did not respond to ping And, I also tried to set Kamailio and rtpengine daemon in a same machine,and use modparam(“rtpengine”, “rtpengine_sock”, “udp:localhost:7723”). And Kamailio can work functionally under this situation. rtpengine daemon can receive ping message from Kamailio and rtpengine daemon can work as suspected. So for the later case, is it supposed that Kamailio be in the same machine with same localhost address? Otherwise, what’s the reason for my ERROR? ------------------------------------ 北京邮电大学网络技术研究院网络与交换技术国家重点实验室田军 +86 18810315790 mozillafire(a)bupt.edu.cn ------------------------------------

Kamctl Stats Update
by Noah Mehl 07 Aug '18

07 Aug '18

Hey all, I was wondering if the kamctl stats output could be updated to provide a bit more parseable JSON? For instance: # kamctl stats shmem | jq . { "jsonrpc": "2.0", "result": [ "shmem:fragments = 18", "shmem:free_size = 467187808", "shmem:max_used_size = 69694104", "shmem:real_used_size = 69683104", "shmem:total_size = 536870912", "shmem:used_size = 41048984" ], "id": 4300 } I would hope would be more like this: { "jsonrpc":"2.0", "result":[ { "shmem":[ { "fragments":18, "free_size":467187808, "max_used_size":69694104, "real_used_size":69683104, "total_size":536870912, "used_size":41048984 } ] } ], "id":4300 } I apologize in advanced because I don’t have the skillset to contribute such a feature. Thanks! ~Noah

No cdr after Kamailio 5.0.4 and 5.2 dev restart
by Kordován Szabolcs 27 Jul '18

27 Jul '18

Hi All, In March there was a discus about this issue. We tested the new 5.2 dev and 5.0.4 version of Kamailio and we experience that If we restart Kamailio during the call the cdr won't be stored in table acc_cdrs but the data will be inserted to table acc and data will be deleted from table dialog and dialog_vars. Did I omit the fix for it? Thanks for your help. Best regards, Szabolcs

Kamailio Behind TCP Load Balancer
by Colin Morelli 04 Jun '18

04 Jun '18

Hey all, I'm looking to put Kamailio behind a TCP load balancer that is SIP-unaware. My application is deployed in AWS and I'm tying to place Kamailio behind an ELB. For the most part, everything is fine. For my specific implementation I'm disabling UDP as a signaling transport and using only TLS. This enables me to not have to worry about a SIP-aware LB at the edge because replies to an incoming request will be sent over the existing established TCP socket (avoiding any crazy routing requirements). However - this poses an issue with source addresses. Does Kamailio support anything like the proxy protocol ( http://www.haproxy.org/download/1.5/doc/proxy-protocol.txt) for getting TCP stream information from a load balancer? Do I need to go back to exposing it directly to the world so that I can get source addresses? Thanks, Colin

Kamailio Websocket Questions

17 Apr '18

Hi List, two questions regarding Kamailio Websockets: 1. How do I send INVITE request TO the listening Websocket? I usually used for UDP/TCP/TLS these format, but somehow this is not working for Websocket because it gets in an endless loop: if ($rU=~"^(\+|00|0)?[1-9][0-9]{4,20}$") { $ru = "sip:" + $rU + "@" + $sel(cfg_get.pstn.gw_ip) + ";user=phone;transport=udp"; force_send_socket(udp:MY_EXTERN_IP:MY_EXTERN_PORT); rtpengine_offer("internal trust-address RTP AVP"); route(RELAY); exit; } 2. Why do I get these errors every time my Websocket Client is registering, but it still works and DB is inserted with registered location: ERROR: <core> [parser/parse_fline.c:257]: parse_first_line(): parse_first_line: bad message (offset: 22) ERROR: <core> [parser/msg_parser.c:690]: parse_msg(): ERROR: parse_msg: message=<HTTP/1.1 101 Switching Protocols#015#012Sia: SIP/2.0/TCP 10.250.5.17:51283#015#012Sec-WebSocket-Protocol: sip#015#012Upgrade: websocket#015#012Connection: upgrade#015#012Sec-WebSocket-Accept: 6uLXlD/aBrzu/j3PYP3DWO7rvLE=#015#012Server: kamailio (4.3.5 (x86_64/linux))#015#012Content-Length: 0#015#012#015#012> I am using Kamailio 4.3.5 + CentOS 7.2.

Hi, Quick (and simple) question: Can someone provide a working RTPengine request, to enable Transcoding? I know, this is possible, but I thought before looking into deep, how this should be configured for the rtpengine_offer() command, could someone provide an example? Thanks, Carsten

But when I use the following DBURL in kamailio.cfg, kamailio fails to even login to mongo: #!define DBURL "mongodb://kam:kam@localhost/kamailio" If I disable mongodb authentication, kamailio starts up just fine again.

Dimensioning ds_hash_size value for dispatcher module

Hi, In the documentation of the dispatcher module it is said that in order to use the algorithm 10 (load balancing) the parameter ds_hash_size must be set, in the definition it is said that the value is in powers of 2, that is to say if it is set to 8, this is equal to 2 ^ 8 = 256 slots, but still I do not understand how to dimension this value for my needs. I do not know whether to put 8, 4, 9, etc. Saludos, ALVARO ARAOS MÉNDEZ Director de Tecnología en FONOIP +56 2 2947 9000 alvaro(a)fonoip.com | www.fonoip.com [1] Moisés Chacón 46, El Monte, RM Links: ------ [1] http://www.fonoip.com

When I try to start kamailio, I get the following error: 0(22216) DEBUG: <core> [db.c:314]: db_do_init2(): connection 0x7f735b5c4100 not found in pool 0(22216) DEBUG: db_mongodb [mongodb_connection.c:55]: db_mongodb_new_connection(): connection open to: mongodb://10.0.12.149 ,10.0.12.150, 10.0.12.151/kamailio?replicaSet=sre_location&slaveOk=true&readPreference=primaryPreferred 0(22216) DEBUG: db_mongodb [mongodb_dbase.c:864]: db_mongodb_query(): query to collection [version] 0(22216) DEBUG: db_mongodb [mongodb_dbase.c:898]: db_mongodb_query(): query filter: { "table_name" : "location" } 0(22216) DEBUG: db_mongodb [mongodb_dbase.c:917]: db_mongodb_query(): columns filter: { "table_version" : 1 } 0(22216) DEBUG: <core> [db_res.c:120]: db_new_result(): allocate 56 bytes for result set at 0x7f735b5c4450 0(22216) DEBUG: db_mongodb [mongodb_dbase.c:746]: db_mongodb_store_result(): no result from mongodb 0(22216) DEBUG: <core> [db.c:404]: db_table_version(): no row for table location found 0(22216) ERROR: <core> [db.c:450]: db_check_table_version(): invalid version 0 for table location found, expected 9 (check table structure and table "version") 0(22216) ERROR: usrloc [dlist.c:659]: register_udomain(): error during table version check. 0(22216) DEBUG: <core> [db_pool.c:100]: pool_remove(): removing connection from the pool 0(22216) ERROR: registrar [registrar.c:651]: domain_fixup(): failed to register domain 0(22216) ERROR: <core> [core/route.c:1154]: fix_actions(): fixing failed (code=-1) at cfg:/usr/local/kamailio-5.1/etc/kamailio/kamailio.cfg:660 0(22216) ERROR: <core> [core/rvalue.c:3860]: fix_rval_expr(): failure in cfg at line: 660 col: 22 0(22216) ERROR: <core> [core/rvalue.c:3860]: fix_rval_expr(): failure in cfg at line: 660 col: 22 0(22216) ERROR: <core> [core/route.c:1154]: fix_actions(): fixing failed (code=-1) at cfg:/usr/local/kamailio-5.1/etc/kamailio/kamailio.cfg:663 ERROR: error -1 while trying to fix configuration 0(22216) DEBUG: tm [t_funcs.c:85]: tm_shutdown(): start 0(22216) DEBUG: tm [t_funcs.c:88]: tm_shutdown(): emptying hash table 0(22216) DEBUG: tm [t_funcs.c:90]: tm_shutdown(): removing semaphores 0(22216) DEBUG: tm [t_funcs.c:92]: tm_shutdown(): destroying tmcb lists 0(22216) DEBUG: tm [t_funcs.c:95]: tm_shutdown(): done 0(22216) INFO: <core> [core/sctp_core.c:53]: sctp_core_destroy(): SCTP API not initialized 0(22216) DEBUG: <core> [core/mem/shm.c:261]: shm_destroy_manager(): destroying memory manager: q_malloc 0(22216) DEBUG: <core> [core/mem/q_malloc.c:1165]: qm_shm_lock_destroy(): destroying the shared memory lock 0(22216) DEBUG: <core> [core/mem/pkg.c:91]: pkg_destroy_manager(): destroying memory manager: q_malloc In mongoDB, I have the collection "version" in the db kamailio, and the entries needed for usrloc (location and location_attrs): sre_location:PRIMARY> use kamailio switched to db kamailio sre_location:PRIMARY> db.getCollection("version").find() { "_id" : ObjectId("5a8ec43c601b262bef82a595"), "table_name" : "location", "table_version" : 9 } { "_id" : ObjectId("5a8edb72a3ec40427577b8d0"), "table_name" : "location_attrs", "table_version" : 1 } And logs in mongo show the following info when kamailio starts: 2018-02-22T17:13:02.604+0100 I NETWORK [conn90] received client metadata from 10.0.12.180:56320 conn: { driver: { name: "mongoc", version: "1.9.2" }, os: { type: "Linux", name: "CentOS", version: "6.9 (Final)", architecture: "x86_64" }, platform: "cfg=0x1563000 posix=200809 CC=GCC 4.4.7 20120313 (Red Hat 4.4.7-18) CFLAGS="" LDFLAGS=""" } 2018-02-22T17:13:02.604+0100 I COMMAND [conn90] command admin.$cmd command: isMaster { isMaster: 1, client: { driver: { name: "mongoc", version: "1.9.2" }, os: { type: "Linux", name: "CentOS", version: "6.9 (Final)", architecture: "x86_64" }, platform: "cfg=0x1563000 posix=200809 CC=GCC 4.4.7 20120313 (Red Hat 4.4.7-18) CFLAGS="" LDFLAGS=""" }, compression: [], $readPreference: { mode: "secondaryPreferred" }, $db: "admin" } numYields:0 reslen:716 locks:{} protocol:op_query 0ms 2018-02-22T17:13:02.604+0100 I COMMAND [conn90] command kamailio.$cmd command: find { find: "version", filter: { table_name: "location" }, table_version: 1, $db: "kamailio", $readPreference: { mode: "primaryPreferred" }, $clusterTime: { clusterTime: Timestamp(1519315979, 1), signature: { hash: BinData(0, 0000000000000000000000000000000000000000), keyId: 0 } } } numYields:0 reslen:531 locks:{} protocol:op_msg 0ms 2018-02-22T17:13:02.605+0100 I NETWORK [conn90] end connection 10.0.12.180:56320 (9 connections now open) I probably miss something: it is not clear to me why kamailio is not able to retrieve the value of table_version for the table_name location. Any idea would be very welcome ! I use mongo-c-driver 1.9.2 and mongodb 3.6 Thank you. Stephane

ways to track all messages of a dialog
by Fabian Borot 09 Mar '18

09 Mar '18

I need to track all messages (SIP Requests, SIP Responses) for some SIP dialogs. Let's say I need to log something specific on each state for calls initiated from a certain IP (initial request, temporary replies, rejection with a negative response, call was accepted with 200, termination with BYE, termination with CANCEL etc. ). I am thinking on using flags but I am not sure after reading the tutorial on flags (http://www.kamailio.org/dokuwiki/doku.php/tutorials:openser-flag-operations) if that is going to work properly. The doc says: "They provide a very easy and fast way of keeping states during processing a request or during a transaction". I am afraid that the ACK if the call is accepted and the BYE won't be tracked properly because they are not part of the initial transaction. Also the doc does not mention if the flag is preserved among branches spawned during the processing of the call. The idea is for example: request_route { if (is_method("INVITE")){ if ($si == "192.168.168.100"){ #condition that would set the flag, INVITE came from "my_IP" #flag/mark dialog setflag(1); #log call from "my_IP" was received } route("INCOMING); } If(loose_route() ){ if (is_method("ACK")){ if(isflagset(1)){ #log ACK related to "my_IP" was received } } if (is_method("CANCEL")){ if(isflagset(1)){ #log CANCEL related to "my_IP" was received } } if (is_method("BYE")){ if(isflagset(1)){ #log BYE related to "my_IP" was received } } } } Then : route["INCOMING"] { # do some processing # do some processing t_onreply("INCOMING"); t_on_failure("INCOMING"); t_relay(); } onreply_route[INCOMING] { #do some processing if(isflagset(1)){ #log a reply related to "my_IP" was received } } failure_route[INCOMING] { #do some processing if(isflagset(1)){ #log a negative reply related to "my_IP" was received } } Will the flags work on this case ? My 2nd approach is to use a htable and use the call_id for my calls as the key. The on each route section (reply, failure_reply, ACK processing etc.) find the $ci on the htable and if it is there do the appropriate action. But I need to delete the key:value once the call ends or leave it autoexpire with a expire value bigger than the max_call_duration_time that we have in our system.

Kamailio Memory Settings
by Duarte Rocha 08 Mar '18

08 Mar '18

Hey. I have some questions about memory settings. I can see the default values with "kamailio -I" and change the current values with "kamailio -M 12 -m 128". How do i see the active settings and how do i change the default value? I want to setup a proxy capable to handle 150CPS, 6k active calls, with Dispatcher, Database, Number Normalizations and other operations. What are good settings for CPU, RAM Memory, PKG_SIZE and SHM_SIZE? Thanks for the help, Best Regards, Duarte Rocha

Strongswan on same Server in EC2 as kamailio 4.4
by Jonathan Hunter 08 Mar '18

08 Mar '18

Hi Guys, I have an issue with sending a BYE message back down a strongswan VPN tunnel on a server in the Amazon EC2 environment. To get the configuration working correctly I have the Public IP address bound to a loopback virtual interface, and I also have kamailio listening to it. Calls establish without issue, but when the called party send a BYE, I cant seem to force the SIP message down the correct interface. Due to client confidentiality I need to be careful what information I send but does anyone have a similar configuration set up, and working, I am just looking for reasons as to why force_socket and mhomed=1 doesnt appear to force the BYE message via the Public Interface but the private IP address on the server as its a NAT'd environment. So essentially call establishes; CLIENT---------(VIA IPSEC)-INVITE----->(UDP)KAMAILIO PUBLIC IP-------->(UDP)KAMAILIO PRIVATE IP(TCP)------------------------->CLIENT B | | | | |<---------(VIA IPSEC)-100 TRYING----|<----------100 TRYING---------------|<----------100 TRYING----------------------------| | | | | |<---------(VIA IPSEC)-180 RINGING---|<----------180 RINGING--------------|<----------180 RINGING---------------------------| | | | | |<---------(VIA IPSEC)-200OK --------|<----------200OK -------------------|<----------200OK --------------------------------| | | | | |----------(VIA IPSEC)-ACk---------> |-----------ACk--------------------->|-----------ACk---------------------------------->| How can I ensure the BYE is forced out via the PUBLIC IP? So I do this; CLIENT---------(VIA IPSEC)-INVITE----->(UDP)KAMAILIO PUBLIC IP-------->(UDP)KAMAILIO PRIVATE IP(TCP)------------------------->CLIENT B |<---------BYE (VIA IPSEC)----------------------|<----------BYE ----------------------------|<----------BYE -------------------| As it appears to be going from Private IP and not being pushed down the IPSEC tunnel CLIENT---------(VIA IPSEC)-INVITE----->KAMAILIO PUBLIC IP-------->KAMAILIO PRIVATE IP------------------------->CLIENT B |<---------BYE ----------------------<----------BYE ----------------------------|<----------BYE -------------------| on the BYE I have tried; force_send_socket(KAMAILIO PUBLIC IP); However doesnt appear to work, is this an issue for ip routing on the server to push the BYE correctly down the IPSEC tunnel? or is it configuration related? Any comments welcome if people have had this issue before. Many thanks Jon
