kamailio as UAC and NAPTR / sendsocket question
by Karsten Horsmann 09 Aug '19

09 Aug '19

Hi List, I try to register to Deutsche Telekom and there product Deutschland Lan siptrunk. Thats works find but i see an intressting behaviour on selecting the right outgoing interface. Kamailio is sending out with tcp the REQUEST via first private ip configured on that server (172.20.120.53). There is no listen directive for that. I forced NAPTR to use tcp or udp and i assume that kamailio got the right dns answers. On the list i read also that i can use force_send_socket to force the outgoing request. Now my idea - hey i use the $rP for the outgoing to select the right outgoing listen directive. $rP - reference to transport protocol of R-URI But to my surprise the logfile told me thats "UDP" - it sends out via TCP (thats okay). Whats an good transport selector variable from kamailio that works? event_route[tm:local-request] { if(!is_method("OPTIONS")) { xlog("L_INFO", "[tm:local-request] request [$rm] from [$fu] to [$ru] [$rP]\n"); } } INFO: <script>: [tm:local-request] request [REGISTER] from [ sip:+49XXXXXXXX@sip-trunk.telekom.de] to [sip:sip-trunk.telekom.de] [UDP] listen=tcp:2xx.xx.xx.xx:5060 listen=udp:2xx.xx.xx.xx:5060 listen=tls:2xx.xx.xx.xx:5061 advertise CFG_EXT_NAME:5061 listen=udp:172.20.120.55:5060 listen=udp:172.20.120.56:5060 listen=udp:172.20.120.57:5060 listen=udp:172.20.120.58:5060 listen=tcp:172.20.120.58:5060 use_dns_cache=on # use internal DNS cache use_dns_failover=on # depends on internal DNS cache dns_srv_loadbalancing=on dns_try_naptr=on dns_retr_time=1 # seconds before retrying a DNS request dns_retr_no=3 # number of DNS retransmissions dns_naptr_ignore_rfc=yes # ignore target NAPTR priority dns_tcp_pref=30 # TCP has second-highest priority dns_udp_pref=10 # use UDP with least priority tcp_connection_lifetime=3605 # set higher than registration expires #dont' restore modparam("uac","restore_mode","none") modparam("uac","restore_dlg",0) ## UAC REGISTER #!ifdef WITH_UAC_REGISTER modparam("uac", "reg_contact_addr", "CFG_PROD_IP") modparam("uac", "reg_timer_interval", 10) modparam("uac", "reg_retry_interval", 10) modparam("uac", "reg_db_url", DBURL) modparam("uac", "restore_mode", "none") modparam("uac", "auth_username_avp", "$avp(AVP_AUTH_USERNAME)") modparam("uac", "auth_password_avp", "$avp(AVP_AUTH_PASSWORD)") modparam("uac", "auth_realm_avp", "$avp(AVP_AUTH_REALM)") #!endif ip a l 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: ens192: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:50:56:b5:c1:48 brd ff:ff:ff:ff:ff:ff inet 172.20.120.53/24 brd 172.20.120.255 scope global ens192 valid_lft forever preferred_lft forever inet 2xx.xx.xx.xx/29 scope global ens192 valid_lft forever preferred_lft forever inet 172.20.120.56/24 scope global secondary ens192 valid_lft forever preferred_lft forever inet 172.20.120.57/24 scope global secondary ens192 valid_lft forever preferred_lft forever inet 172.20.120.58/24 scope global secondary ens192 valid_lft forever preferred_lft forever inet 172.20.120.55/24 brd 172.20.120.255 scope global secondary ens192 valid_lft forever preferred_lft forever inet6 fe80::250:56ff:feb5:c148/64 scope link valid_lft forever preferred_lft forever default via 172.20.120.253 dev ens192 172.20.120.0/24 dev ens192 proto kernel scope link src 172.20.120.53 2xx.xx.xx.xx/29 dev ens192 proto kernel scope link src 2xx.xx.xx.xx -- Kind Regards Mit freundlichen Grüßen *Karsten Horsmann*

Hello guys, I can't find any reference to a pseudovariable containing the request url, i.e.: http://myserver/XMLRPC?server=1.2.3.4 I'd like to get that server variable and manipulate the dispatcher list... the http client can't do XMLRPC or add a body, just an https request..

Breaking HTABLE changes from v5.2 to v5.3? Function renamed
by Joel Serrano 08 Aug '19

08 Aug '19

Hi all, Just noticed that when updating from 5.2 to 5.3 I saw some errors in Kam logfile regarding HTABLE module commands failing, the reason is the function 'sht_has_name' has been renamed to 'sht_match_name': https://www.kamailio.org/docs/modules/stable/modules/htable.html#htable.f.s… https://www.kamailio.org/docs/modules/devel/modules/htable.html#htable.f.sh… Not sure if updating this doc is automatic or manual but I think it's definitely worth mentioning: https://www.kamailio.org/wiki/install/upgrade/stable-to-devel Just FYI! Cheers, Joel.

Reload geoip2 database without restart
by Joel Serrano 07 Aug '19

07 Aug '19

Hi guys, Is there a way to instruct the geoip2 module to reload its database without a full restart of kamailio? Maybe some rpc command or something? I haven't found anything in the docs other than the comment about "Database is loaded at startup in cache." which makes me assume that just overwriting the db file wouldn't be enough. Any suggestions? Thanks!! Joel.

Sipt redirection number retrieves old values
by Duarte Rocha 07 Aug '19

07 Aug '19

Greetings, I'm doing VoiceMail detection using $sipt(redirection_number) from SIPT module and i've been having some false positives on the detection. I inspected further and noticed that in some cases $sipt(redirection_number) returns old values from previous messages, which makes me think that it's value is not being correctly refreshed. I'm using this variable on a on_reply_route. As far as i know, $sipt(redirection_number) is read only and can't be refreshed by me in the code. Here is an example : Aug 7 16:51:49 dev_sbc_a_vts01 /usr/local/kamailio-5.2/sbin/kamailio[4746]: ERROR: <script>: VMD2 : Reply Code : 180 ; Sipt Redir = 9610050000 and Call ID = 00158FED-98B7-E911-8B3B-4DA50AE2ED72(a)192.168.24.86 and Cseq = 83 Here is the JSON from the 180 message : https://pastebin.com/zFHKxyav As you can see, there isn't any 9610050000 in the message. What can be causing this issue ? Best Regards, Duarte Rocha

app_ruby - invalid ruby environment attributes or parameters
by Andrew White 07 Aug '19

07 Aug '19

Hey all, I’m setting up a dev-7 (bd477f) server to test as per the other thread, however I’m getting the following loading my config: ERROR: app_ruby [app_ruby_api.c:465]: sr_kemi_ruby_exec_func_ex(): invalid ruby environment attributes or parameters I’m unsure what this error means - are there expected environment variables or other values that must be set? I didn’t see this issue in dev-4. I thought it might be not able to find the library, but I ran with debug=4 and saw: DEBUG: app_ruby [app_ruby_api.c:193]: ruby_sr_init_child(): test execution without error ERROR: app_ruby [app_ruby_api.c:107]: app_ruby_print_last_exception(): exception: undefined method `>' for false:FalseClass I changed kamailio.cfg to load my generic routing script, and during the onreply_manage it runs: scode = KSR::PV.get("$rs”) This now returns false (which appears to be the second error above, I check if scode is > 599). Has anything changed in the way ruby is loaded in dev-7? I’m using the same ruby/ruby-devel library versions on the same OS. I did this deploy the same with devel-4 a few weeks ago and this didn’t happen. Thanks! Andrew

The domain module in 5.1.8 has a memory leak
by Mack Hendricks 06 Aug '19

06 Aug '19

Based on my tests, the memory leak is only exposed when you are using domain attributes, which are stored in the domain_attrs table. I wanted to see if anymore else is running into this issue. *Reproducible use case:* 1) Insert the following into the database insert into domain values (null,"aprilco.com","aprilco.com",now()); insert into domain_attrs values (null,"aprilco.com","pbx_type",0,"0",now()); insert into domain_attrs values (null,"aprilco.com","pbx_id",0,"65",now()); 2) Open a new terminal window and execute: watch "kamcmd core.shmmem" 3) Open up another terminal windows and execute: while true; do kamcmd domain.reload; done *Expected Results:* You will see the shared memory being allocated, but never freed. The more entries you have in the domain_attrs table, the faster it will run out of memory.

Error Registering the user and finding the AVP
by jespinosa 06 Aug '19

06 Aug '19

Hello, My name is Javier, I must first apologize for my little knowledge about the tool and my poor English. I am trying to connect a functional core network LTE with Kamailio and I have used the Polaris Networks Solution that brings an iso with both functionalities. The EPC is correctly configured and working because I can have data connection in my UE, I have also activated all the IMS options in the EPC: I have created the APN with ims identifier, the default carrier QCI assigned is 5 (for SIP signaling), the MME has activated the option to support IMS Voice over the PS session and the HSS and PCRF nodes are configured with the interfaces at the addresses and ports Cx-HSS 127.0.0.1:3868 and Cx-PCRF 10.11.0.35:3868 . There are several parameters that I do not know if it is necessary to activate, for example, in the PCRF the customization of the QCI for the media type, if I must include the OCS and OFCS as nodes, or if in the profile of my APN I must include authentication by PDN AAA. The configuration I use for the IMS is as follows: imsrealm = net1.test imsport = 5060 pcscfgmip = 10.77.0.35 pcscfgmipintf = eth6 pcscfrxip = 10.102.81.111 pcscfrxipintf = eth1 icscfmwip = 127.0.0.21 icscfmwipintf = lo:21 icscfcxip = 127.0.0.20 icscfcxipintf = lo:20 scscfmwip = 127.0.0.23 scscfmwipintf = lo:23 scscfcxip = 127.0.0.22 scscfcxipintf = lo:22 audiobandwidth = 64 videobandwidth = 128 epcrealm = epc.mnc001.mcc001.3gppnetwork.org pcrfhost = pcrf2.morsecore pcrfrxip = 10.11.0.35 pcrfrxport = 3868 hsshost = hss6.morsecore hsscxdxip = 127.0.0.1 hsscxdxport = 3868 Both cores are running on the same machine but I have disabled the option of PCRF Co-located with IMS to be able to edit the pcrf host name since if I enable it it does not reach the peer pcrf.localhost even if the DNS is well configured. My UE is not able to launch the REGISTER by itself when it is going to make a call, so I am using the Google IMSDroid application to be able to launch the SIP requests and check the operation of the IMS. In the application of the UE the configuration is as follows: Identity: Alice Public Identity: sip:<MSISDN>@net1.test (MSISDN=8800000451 configurado previamente en el EPC) Private Identity: sip:<IMSI>@net1.test (IMSI incluyendo MCC y MNC) Password: alice Realm: net1.test (Aunque no sé si debo poner aquí epc.mnc001.mcc001.3gppnetwork.org, pero entonces la petición da error) Network: Proxy-CSCF Host: 10.77.0.35:5060 Transport UDP and NO Proxy-CSCF discovery.

Hi Team, Facing 100% Kamilio CPU issue, here are the details, any pointers/hints would help. Thanks *Scenario:* Random Kamailio CPU shoot, restart fixes it. Happens once or twice in a day.

Re: [SR-Users] Kamailio v5.2 kamctl alias add problem
by Igor Potjevlesch 04 Aug '19

Hi kamailio Users, I meet a problem with the " kamctl alias add" command in the 5.2 version, I saw that the module used to add an alias had changed, and now the command result with an error : [kamailio]# kamctl alias add XXXX@XXXX sip:XXXXX@XXXX { "jsonrpc": "2.0", "error": { "code": 500, "message": "Not enough parameters or wrong format" }, "id": XXXXX } So in the version 5.2, the table aliasdb replace the table alias ? We are using the table alias for the incomming call, and we implemented scripts to add with the command kamctl alias add the information needed in the tavble alias to route the call. But since the version 5.2 we need to add an argument "path" in this command, and we don't know how to put it at "NULL" or how we can use this argument ? Can you help us with this?

Hi all, I've tried to create a reverse proxy to forward incoming request that came from SIP provider to Asterisk PBX and forward the requests from asterisk to kamailio then sip provider. What i get is that I see the invite, but is like no ACK. Thanks in advance.

Hey all, looking for a little help. I've been tracking an issue, where a number of SIP Messages ( typically INVITE ) are sent, but Kamailio only see one of them ( the last one). I have verified that the messages are definitely received on the host, as verified with TCPDUMP, but the INVITES never hit the request route block. ( the very first thing is to log the message ) What i've managed to find is, that if I increase worker children, the problem goes away. So I've got a problem, I think I've found the solution, but what I'm struggling with is how to monitor better, so I can be alerted to this in the future. I started by looking at "kamctl stats | grep drop" "core:drop_replies = 14", "core:drop_requests = 10577" however drop_requests seems to include explicit drops in my config. which I do for many reasons, but mainly bad UA or blocked IP's, so this dosnt seem to be what im after. I then went digging in the code ( often the best way to find things ). in receive.c receive_msg() we find some conditions, where we drop the packet ( before calling request route ). right now im looking around line 251 at LM_DBG("dropping the received message\n"); goto error00; Following error00 I see it calls STATS_RX_DROPS which increments stats->received_drops. This is where it gets fun, I cant find where received_drops is ever returned in the stats output. I can see where -SIGUSR1 will trigger this to be dumped, if Kamailio is compiled with that option ( dosnt seem the debian packages are ). however, what im seeking clarification on is, does this get reported in "kamctl stats" Am I just going crazy or is something not quite right here? TLDNR; how do I monitor for Kamailio not having enough worker threads to process incoming messages. FYI I'm seeing about 50Mbps of incoming SIP on this box, and I do perform a decent amount of work on some message types. -- Sincerely Jay

Deleting extra location attribute(location_attrs table) when contact is expired
by Pintu Lohar 31 Jul '19

31 Jul '19

Hi All, Regarding modparam("tm|usrloc", "xavp_contact", "ulattrs") #ref : https://www.kamailio.org/docs/modules/devel/modules/usrloc.html#usrloc.p.xa… . There is some requirement where we need to save some extra location attributes to location_attrs <https://kamailio.org/docs/db-tables/kamailio-db-4.3.x.html#gen-db-location-…> tables $xavp(ulattrs=>deviceIdentify)= "Some str values" and calling save(“location”) , It works well and saved location attribute table but But when contact expired callback is received, udomain_contact_expired_db() does not it delete the extra location attribute from database but deleting the record from location table only ? If not, is there any recommended approach to delete the extra location attributes from the database? or am I missing something to set? Alternate I was thinking could be running timer from Kamailio config and check last_modified time and delete those(based on our UAC expiry setting), is it the right approach. Kamailio Version: 5.2.0. Thanks for your valuable suggestion in advance. Regards Pintu Lohar
