Lost connection to MySQL server during query
by JR Richardson 29 Mar '19

29 Mar '19

Hey Folks, Getting some annoying logs, pretty certain these are false positives. I'm running kamailio 4.4.7 using localhost mysql 5.5.60 on debian 7.11. Pretty simple setup, have acc and collecting cdrs. Relevant kamailio.cfg: loadmodule "acc.so" loadmodule "rtimer.so" loadmodule "sqlops.so" # ----- acc params ----- modparam("acc", "db_url", DBURLRW) modparam("acc", "db_flag", 1) modparam("acc", "db_missed_flag", 2) modparam("acc", "db_extra", "src_user=$fU;src_domain=$fd;src_ip=$si;" "dst_ouser=$tU;dst_user=$rU;dst_domain=$rd;" "accountcode=$avp(s:acctcode)") modparam("rtimer", "timer", "name=cdr;interval=300;mode=1;") modparam("rtimer", "exec", "timer=cdr;route=CDRS") modparam("sqlops", "sqlcon", "cb=>mysql://rwuser:rwpass@localhost/kamailio") route[CDRS] { sql_query("cb","call kamailio_cdrs()","rb"); } Logs: ERROR: db_mysql [km_dbase.c:128]: db_mysql_submit_query(): driver error on query: Lost connection to MySQL server during query (2013) ERROR: <core> [db_query.c:181]: db_do_raw_query(): error while submitting query ERROR: sqlops [sql_api.c:265]: sql_do_query(): cannot do the query [call kamailio_cdrs()] CDRs are working fine, no issues with the results, just the log messages. Errors occur every 5 minutes so this is related to the rtimer cycle, mode=1 is set for new connection so there really wouldn't be a lost connection, the old connection should have been relieved on last cycle. I've seen some other post talking about this issue but could not find any resolution or work around. Any help is appreciated. Thanks.

28 Mar '19

Hello - Is there a way I can print current timestamp in milli or microseconds in the log file? Something like: 2019-03-28 04:50:15.379 would be ideal The closest thing I could find was $TV(Sn) but it doesn't suit the purpose here since its not human readable. Thanks Pat

flags definition in kamailio.cfg + 5.2 documentation
by Joel Serrano 27 Mar '19

27 Mar '19

Hi, I saw in the Kazoo default.cfg this: ... ####### Flags ####### flags FLAG_INTERNALLY_SOURCED: 1, FLAG_ASSOCIATE_SERVER: 2, FLAG_SKIP_NAT_CORRECTION: 3, FLAG_ASSOCIATE_USER: 4, FLAG_TRUSTED_SOURCE: 5, FLAG_SESSION_PROGRESS: 6, FLAG_IS_REPLY: 7, FLAG_SIP_TRACE: 8; ... So then I went here to read about it: https://www.kamailio.org/wiki/cookbooks/5.2.x/core#flags I found out it's not documented... is this a drop-in alternative for a: #!define FLAG_NAME FLAG_BIT? Sorry, first time I see this if not I would update the docs myself... :( Thanks, Joel.

Manipulating User Agent header in dispatcher OPTIONS
by Andrew White 27 Mar '19

27 Mar '19

Hi all, I’ve set the server_header variable in my primary config, and I’ve got a catch in the default reply route to modify headers where required. I’m masking this value for security reasons, and filling it with my own value for vanity reasons :). I’ve noticed that the OPTIONS packet that is send via the dispatcher module when probing mode is on contains a User-Agent field which has the full version and OS type. Unfortunately I don’t necessarily have trust of the end destination being dispatcher to, nor the packet switchers in-between. How can I catch this OPTIONS packet to manipulate the value? It doesn’t appear to go through the REQUEST route or the ONSEND route. Thanks! ________________________________ Andrew White - Director uConnected Email: andrew(a)uconnected.com.au Web: www.uConnected.com.au

accounting and db_redis

Under https://www.kamailio.org/docs/modules/5.2.x/modules/db_redis.html#db_redis.… there is an example for using db_redis for accounting. This doesn't appear to work (5.2.2) modparam("db_redis", "keys", "acc=entry:callid,time_hires&cid:callid") results in: db_redis [redis_dbase.c:1886]: db_redis_insert(): inserting to prefix (table) 'acc' db_redis [redis_dbase.c:382]: db_redis_build_entry_keys(): build entry keys db_redis [redis_dbase.c:295]: db_redis_find_query_key(): checking for existence of ent db_redis [redis_dbase.c:306]: db_redis_find_query_key(): found key in entry key db_redis [redis_dbase.c:133]: db_redis_val2str(): converting str value '1db9c0bc57291e db_redis [redis_dbase.c:338]: db_redis_find_query_key(): entry key so far is 'acc:entr db_redis [redis_dbase.c:295]: db_redis_find_query_key(): checking for existence of entry key 'time_hires' in query db_redis [redis_dbase.c:346]: db_redis_find_query_key(): key 'time_hires' for type 'entry' not found, unable to use this type db_redis [redis_dbase.c:405]: db_redis_build_entry_keys(): Failed to create direct entry key, no matching key definition db_redis [redis_dbase.c:1892]: db_redis_insert(): failed to build entry keys db_redis [redis_dbase.c:1976]: db_redis_insert(): failed to do the insert What does work is "time" instead of "time_hires". Since I have no idea what values are available (I guess the table names?) and time only has a 1 sec resolution, what is a correct version of time_hires?

DBText does not exists!

27 Mar '19

Hi all, I’m currently playing with the UAC module to hand off remote registrations with trunks to Kamailio. I want to keep Kamailio’s external connections low, so I’m planning to use db_text to load the UAC info, and populate the flat file via other methods. When attempting to load my UAC DB via db_text however, I get the following: Mar 26 04:59:30 ip-10-0-0-2 /usr/local/sbin/kamailio[31904]: ERROR: db_text [dbt_lib.c:143]: dbt_cache_get_db(): database [/etc/kamailio/uac.db] does not exists!

Extract URI from Headers
by Duarte Rocha 27 Mar '19

27 Mar '19

Greetings, In my SBC i usually have to do operations on P-Asserted-Identity and Contact header. For those operations i usually have to get the user part, domain, etc. For that i'm using the URI Transformations provided by Kamailio. However, in order to do this i have to trim the header value by hand in order to remove brackets, display infos, etc. Does Kamailio have a method for extracting the URI from those kinds of headers? Best Regards, Duarte Rocha

Disable Dispatcher GW from DB
by Patrick Wakano 26 Mar '19

26 Mar '19

Hello list, Hope you are all doing well! I am looking for a way to disable a Dispatcher GW from the DB. I know I can disable it using the "kamcmd dispatcher.set_state d ..."command, but in case I do a reload or restart after that, the disabled GW will be back as active. Of course I could also delete the GW from DB, but for CDR purposes I want to keep the entry but mark as permanently disabled, so Kamailio won't try to use it nor ping it anymore. Does anyone how can I do that in the DB? I am looking for the exact same behavior the "kamcmd dispatcher.set_state d" does but from some change in the DB. Thanks, Kind regards, Patrick Wakano

Presence module. How to update contact DB record after re-SUBSCRIBE ?
by Denys Pozniak 26 Mar '19

Hello! We are using Presence module with MySQL with parameters below. And looks like module does not update contact DB record in case of re-SUBSCRIBE. So we have a case when NAT router periodically changes the outgoing port, but NOTIFY from Kamailio goes to port from initial SUBSCRIBE.

Adding presentity_uri prefix for multi-tenanted presence/dialoginfo configuration
by Rhys Hanrahan 26 Mar '19

26 Mar '19

Hi Everyone, I’ve recently just started working with Kamailio – thanks everyone for this amazing software. Like many people, I’m in the process of trying to put Kamailio in-front of Asterisk to allow it to scale out, and my plan is for Kamailio to take over registrations, usrloc and presence/dialoginfo, as we’ve had issues where handsets are failing to get BLF updates/notifys, so I am hoping a couple of Kamailio boxes can scale better in this regard. DMQ is particularly exciting in how it will allow me to build a truly distributed platform. But I’m struggling to get presence to work the way I need it to. Our environment is multi-tenanted, but we do not (and can’t really) use multi-domains. Instead, we prefix the SIP usernames with the “tenant name” such as tenanta101 and tenantb101. My problem is that all the BLFs are configured for 101@PBX with no tenant name in the User part of the URI so that internal dialing and call pickup will work. Because in Asterisk we use “subscribecontext” this hasn’t been a problem in the past – Asterisk knows for subscriptions coming from that handset that it belongs to that tenant’s context in the dialplan and they are “isolated”, so having handsets subscribe as 101@ in their request URI was never a problem. Of course, with Kamailio I don’t have subscribecontext, and my main issue is that the “presentity_uri” being stored is 101@ while each of the SIP accounts of the handsets are registered as tenenata101@, and as such, no NOTIFYs are sent by Kamailio because it thinks that there are no watchers for the presentity_uri. If I change the SIP account username to 101 to match the BLF key, NOTIFYs are sent as expected. But then this breaks call pickup and internal dialing using the BLF keys. I would rather handle this in Kamailio than in Asterisk and having to re-configure the BLF keys for hundreds of handsets. I need to do something like: * When a SUBSCRIBE comes in, I need to prefix presentity_uri with the tenant name so the subscription changes from 101@ to tenanta101@ in the active_watchers table. * When Kamailio generates a NOTIFY, the notify would be built based on presentity_uri and would come out as tenanta101@, but the phone’s BLFs are configured for 101@ so I would need to *remove* the tenant prefix before sending out the notify. Is there a good, or recommended way to handle this scenario? Maybe something entirely different to changing the presentity_uri? I’ve written the following config to re-write the request URI and To field in any incoming subscribe requests, and successfully got the active_watchers table to store a presentity_uri containing my tenant prefix. But the problem I am having is that I can’t figure out how to modify the NOTIFY packets before they are sent – and looking at cfgtrace, it seems I might not be able to? My “standard” presence + dialoginfo configuration was taken from here as a starting point: https://kb.asipto.com/kamailio:presence:k43-blf Here is what I have so far in terms of trying to make my modifications – any guidance would be greatly appreciated. It feels like there’s probably a better way to do this than re-writing critical headers like To and Request URI? @@ -466,6 +467,8 @@ request_route { # authentication route(AUTH); + route(REWRITE_PRESENCE); + # record routing for dialog forming requests (in case they are routed) # - remove preloaded route headers remove_hf("Route"); # Presence server processing route[PRESENCE] { if(!is_method("PUBLISH|SUBSCRIBE")) return; if(is_method("SUBSCRIBE") && $hdr(Event)=="message-summary") { # Asterisk is our voicemail route(TOASTERISK); # returns here if no voicemail server is configured sl_send_reply("404", "No voicemail service"); exit; } #!ifdef WITH_PRESENCE if (!t_newtran()) { sl_reply_error(); exit; } if(is_method("PUBLISH")) { handle_publish(); t_release(); } else if(is_method("SUBSCRIBE")) { # See REWRITE_PRESENCE - this should have been executed before we get here. handle_subscribe(); t_release(); } exit; #!endif +route[REWRITE_PRESENCE] { + if (is_method("SUBSCRIBE")) { + xlog("Re-writing subscribe to include tenant prefix\n"); + # The default presentity_uri needs to be prefixed with + # the tenant name + # So re-write the To header + route(TENANTINFO); + # Now grab the tenant name. + $var(subscribe_ru) = "sip:" + $var(tenant_name) + $rU + "@" + $rd; + xlog("Re-writing SUBSCRIBE To header as: $var(subscribe_ru)\n"); + insert_hf("To: $var(subscribe_ru)\r\n", "From"); + $ru = $var(subscribe_ru); + # Force change immediately: + # http://www.kamailio.org/wiki/tutorials/faq/main#why_changes_made_to_headers… + msg_apply_changes(); + } else if (is_method("NOTIFY")) { + xlog("Re-writing NOTIFY to remove tenant prefix\n"); # This code block does not get executed right now. + # We are storing the presentity_uri with a tenant prefix + # handsets do not expect this, only 101@, 102@ etc...

Default port interference in TLS conneciton
by Dalibor Zeman 24 Mar '19

24 Mar '19

Hello, I am running Kamailio v. 5.1.2 with typical configuration for wss connections (default config + tls, websocket, nathelper modules), quite everything is running as should, but I am quite concerned about what I got on Homer server. My Kamailio is listening on port 4443 for TLS. Opening dialog runs as should, then UPDATE and BYE messages are received on 4443, but sent out on 5060. When I don't set up default port, 403 reply comes on a call. I'd like to know whether it is something defined by standard or it has a meaning and I should leave it as it is, or I should correct it somehow and then how. Also, if it has a meaning, then what it is. Thanks for your answer, Dalibor Zeman.

KEMI Ruby - exit from within function
by Andrew White 23 Mar '19

23 Mar '19

Hi all, I know ruby is pretty new to KEMI, so I understand this might not be supported. I’ve been able to build a functional basic configuration using KEMI based app_ruby. However the function KSR::x.exit is not exposed to the interpreter. Reading up on the function (https://kamailio.org/docs/tutorials/devel/kamailio-kemi-framework/kemimods/… <https://kamailio.org/docs/tutorials/devel/kamailio-kemi-framework/kemimods/…>) I can see either a native `exit` or a return from the request_route is recommended. The latter of these works fine, however the former throws the following error when called either within the request_route function or any others: Mar 22 03:40:46 guest /usr/sbin/kamailio[17474]: ERROR: {1 19731 BYE 8u6We4ReU01GuU-zoa7VuqC.qWwwg29S} app_ruby [app_ruby_api.c:105]: app_ruby_print_last_exception(): exception: exit Mar 22 03:40:46 guest /usr/sbin/kamailio[17474]: ERROR: {1 19731 BYE 8u6We4ReU01GuU-zoa7VuqC.qWwwg29S} app_ruby [app_ruby_api.c:1078]: app_ruby_run_ex(): ruby exception (6) on callback for: ksr_request_route (res type: 17) It appears the app_ruby wrapper is seeing an exit as an exception and throwing an error. I’m unsure if this is affecting my actual flow (still building the config), but the error in the logs is certainly annoying. Returning from the request_route function works fine, however this is obviously harder to do from within a sub function. Any direction on how to correctly exit in similar ways to native or other KEMI implementations would be appreciated. By the way, thanks Daniel for writing this module! This makes Kamailio significantly more accessible for myself and others like me! ________________________________ Andrew White - Director uConnected Email: andrew(a)uconnected.com.au Web: www.uConnected.com.au

Kamailio initial log - Mysql error
by Jorge Cornejo 22 Mar '19

22 Mar '19

Hi, I am new at Kamailio, I have installed a vicidial goautodial box and having some headaches. I can see at starup logs the following message: Mar 18 02:12:34 edialer1 /usr/sbin/kamailio[4028]: ERROR: db_mysql [km_my_con.c:129]: db_mysql_new_connection(): driver error: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2 "No such file or directory") Mar 18 02:12:34 edialer1 /usr/sbin/kamailio[4028]: ERROR: <core> [db.c:318]: db_do_init2(): could not add connection to the pool Mar 18 02:12:34 edialer1 /usr/sbin/kamailio[4028]: ERROR: usrloc [dlist.c:654]: register_udomain(): failed to open database connection However if I execute the following command: [root@edialer1 kamailio]# kamctl db show subscriber database engine 'MYSQL' loaded Control engine 'RPCFIFO' loaded +----+------------+----------------------------+----------+---------------+- ---------------------------------+----------------------------------+------+ | id | username | domain | password | email_address | ha1 | ha1b | rpid | +----+------------+----------------------------+----------+---------------+- ---------------------------------+----------------------------------+------+ | 18 | 5474470533 | vaglxc01.goautodial.com | | NULL | 10685ad93a251bb460e7dd544a174288 | 1680d2aebe5f750c4eedb45ad6b5ba4f | NULL | | 20 | 5505791853 | edialer1.gevolution.com.br | | NULL | 04e377e3923716fb5038b0caa79b8ed3 | d65362c7ccd934f00efa21c45e479ec5 | NULL | | 21 | 2347600834 | edialer1.gevolution.com.br | | NULL | 065fc461faa06cec682213cf17352630 | 4d79bc7db16f74d13d1785dafb30391c | NULL | +----+------------+----------------------------+----------+---------------+- ---------------------------------+----------------------------------+------+ I get a DB response.so is Kamailio actually connected to the db or not? Also at logs I get Mar 18 02:13:35 edialer1 /usr/sbin/kamailio[4513]: DEBUG: db_mysql [km_res.c:66]: db_mysql_get_columns(): 1 columns returned from the query So I assume it read from the DB something.This is quite confusing as can't say properly if it is working or not. Why I am not sure? Because can't see any information on it sending information to asterisk listening on port 5070, logs won't show such action. As I can't find the asterisk information at the kamailio.cfg file, I assume it is stored at the DB, and if DB connection is broken, would explain why it doesn't work. Can you please help me to figure this out? Thanks in advance

How fair is the rtpengine loadbalancing?
by Daniel Tryba 22 Mar '19

22 Mar '19

I have 3 rtp backends defined with equal weights (33 each). But when I look at the number of calls being handled the spreaded load is always 5:4:3 for the machines in the orderd listed: modparam("rtpengine", "rtpengine_sock", "udp:10.235.32.60:7723=33 udp:10.235.32.59:7723=33 udp:10.235.32.58:7723=33") Looking at select_rtpp_node_new I see nothing unfair happening (with my total lack of knowledge of how the node set is populated). Anybody else noticing this?

Auth for SUBSCRIBE and others
by Kevin Olbrich 22 Mar '19

22 Mar '19

Hi! I am implementing forwarding of SUBSCRIBE (BLF) to an Asterisk behind Kamailio. This works but Kamailio is not requesting for Auth. I then added SUBSCRIBE to: https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg#L746 And it now challenges the client correctly. Why does this line only show REGISTER? Shouldn't it request a challenge for all messages? And why does it work with INVITES ootb? Thank you! Kind regards Kevin
