tls.cfg and configuration
by Aymeric Moizard 17 Jan '24

17 Jan '24

Hi all, I'm using a central file to define my kamailio cfg configuration. First question: In my main kamailio.cfg, I use: include_file "kamailio-config.cfg" which contains: #!substdef "!MY_DOMAIN!kamailio.example.com!g" I would like to use the same in tls.cfg which is defined this way: modparam("tls", "config", "/etc/kamailio/tls.cfg") but I get: sr_cfg_parse(): tls.cfg:17:1: Unsupported option 'include_file' Would you advise some way to achieve my goal: ie, I would like only one file to edit my configuration options which would have an effect on both kamailio.cfg and tls.cfg Second question: Can someone confirm that #!substdef will also not have any effect when used in tls.cfg Thanks Aymeric -- Antisip - http://www.antisip.com

Not checking SRV records
by Jon Bonilla (Manwe) 13 Jan '24

13 Jan '24

Hi This may be a stupid question but after a couple of hours and some headache I can't see where the problem is. I'm trying to use SRV records to relay to different servers as I've done many many times before. But in this case I'm getting a 478 from kamailio and I see that it's not trying to resolve SRV. From the log: [core/dns_cache.c:527]: _dns_hash_find(): (fs.mydomain.dev(16), 1), h=632 [core/resolve.c:784]: get_record(): lookup(fs.mydomain.dev, 1) failed [core/dns_cache.c:761]: dns_cache_mk_bad_entry(): (fs.mydomain.dev, 1, 60, 1) [core/dns_cache.c:701]: dns_cache_add(): adding fs.mydomain.dev(16) 1 (flags=1) at 632 [core/dns_cache.c:2807]: dns_a_resolve(): (fs.mydomain.dev, 0) returning -7 [core/dns_cache.c:3176]: dns_srv_sip_resolve(): (fs.mydomain.dev, 0, 0), ip, ret=-7 uri2dst2(): failed to resolve "fs.mydomain.dev" :unresolvable A or AAAA request (-7) When doing tcpdump port 53 I see A record query but no SRV SRV records of course exist although they are not being checked. dns params in kamailio: dns_try_ipv6=no dns_retr_time=1 dns_retr_no=1 dns_use_search_list=no use_dns_cache=on use_dns_failover=on dns_srv_lb=on dns_try_naptr=no dns_sctp_pref=1 dns_tcp_pref=1 dns_tls_pref=1 dns_udp_pref=1 Same exact config in another server is working.

Internal DNS resolver
by Igor Potjevlesch 12 Jan '24

12 Jan '24

Hello! I have a quick question about the internal DNS resolver and cache embedded in Kamailio. Is the ability to add an entry with dns.add_a bypass the "real" DNS lookup? So, let's say that sip.example.com is publicly resolve alternatively with 1.2.3.4 & 5.6.7.8.9, if I do a dns.add_a to add my own sip.example.com with, alternatively, 127.0.0.1 and 127.0.0.2, will it work? Thanks for your highlight! Regards, Igor. -- Cet e-mail a été vérifié par le logiciel antivirus d'Avast. www.avast.com

Hey!

Clarification on usrloc timer_interval param and contact-expires event route.
by James Lipski 12 Jan '24

12 Jan '24

Hello, Just need a bit of clarification on the usrloc parameter "timer_interval". Let's say this is configured with a value of 60 seconds; every 60 seconds, will this delete all expired contacts in the location table between runs -- as in between runs it will queue up a list of expired contacts, remove them all after the 60 seconds has elapsed, then execute the event route "event_route[usrloc:contact-expired]"? Or does the event route execute as soon as the contact expires, independent from "timer_interval" timer? Thank you.

Good evening everyone, I'm trying to configure my Kamailio to use another DB in case the one it commonly uses fails. Does Kamailio has any built in function to do this?

Timeout on forwarding REGISTRATION
by dries＠degendt.com 10 Jan '24

10 Jan '24

Hi all, My Kamailio server has been throwing a lot of errors during the manipulation and forwarding of registrations to my Asterisk server (192.168.96.97) using uac_req_send(); and t_relay() [core/tcp_main.c:1402]: tcp_do_connect(): connect 192.168.96.97:5060: (99) Cannot assign requested address [core/tcp_main.c:1399]: tcp_do_connect(): connect 192.168.96.97:5060 failed Cannot assign requested address When looking deeper into the code it appears that the errors are thrown when "tcp_async" is enabled. I've enabled this option a few weeks ago to make sure clients can REGISTER quickly. The parameter "tcp_reuse_port" is also set to yes. I'm suspecting that on busy moments, the destination can't be reached because no TCP connections are available. Is there any of the following parameters that I can adjust to prevent this issue? tcp_children = 25 disable_tcp = no tcp_max_connections = 63536 tcp_connection_lifetime = 3605 tcp_accept_aliases = no tcp_async = yes tcp_connect_timeout = 10 tcp_conn_wq_max = 65536 tcp_crlf_ping = yes tcp_delayed_ack = yes tcp_fd_cache = yes tcp_keepalive = yes tcp_keepcnt = 3 tcp_keepidle = 30 tcp_keepintvl = 10 tcp_linger2 = 30 tcp_rd_buf_size = 80000 tcp_send_timeout = 10 tcp_wq_blk_size = 2100 tcp_wq_max = 10485760 tcp_reuse_port=yes /* tcp_connection_match=1 */ open_files_limit=63536 A quick tcpdump doesn't show outgoing packet during the error events.

Re: uac_req_send + evroute + crash

Hello, Any idea about the crash below? I found a ticket regarding to this, I made some comments and backtraces there also: https://github.com/kamailio/kamailio/issues/3635 Now this crash is very frequently, 3-4 times every day. There is a timer mechnism, where kamailio refreshes registrations towards asterisk automically to ensure continuous availability for mobile users. The crash exists 3-5 secs after this refresh process, but not always. Sometimes this process runs fine only CRITICAL logs appears (mentioned below) after it, but sometimes kamailio crashes during writing these CRITICAL logs.

Hello, When using http_async_query function, provided by module http_async_client: https://www.kamailio.org/docs/modules/devel/modules/http_async_client.html#… If module "tm.so" is not loaded, then immediately upon calling function http_async_query, Kamailio crashes: 9(3807541) CRITICAL: <core> [core/pass_fd.c:281]: receive_fd(): EOF on 8 0(3807527) ALERT: <core> [main.c:791]: handle_sigs(): child process 3807533 exited by a signal 11 0(3807527) ALERT: <core> [main.c:795]: handle_sigs(): core was generated 0(3807527) INFO: <core> [main.c:818]: handle_sigs(): terminating due to SIGCHLD Of course, I now know that I must load the module "tm.so".

DB invalid connection parameter

Hi, Facing the following error after bumping Kam from 5.3 => 5.4 => 5.5 => 5.6, following instructions on each step about DB structure and module changes. These errors show up since.

webRTC Test Client?
by Andy Newlands 03 Jan '24

03 Jan '24

Hi, I have a Freeswitch installation, fronted by a Kamailio proxy I would like to configure Kamailio to bridge SIP between webRTC clients and Freeswitch. The first issue I hit is how to set up a test webRTC client to make calls into Kamailio/FS. Can anyone point me to a simple webRTC client I can use to make test webRTC/SIP calls into my setup? Thanks BTW: I'm not JS experienced (I work with Python, C#, C/C++). Kind regards, Andy

Info: Next Kamailio World Conference - April 18-19, 2024, Berlin, Germany
by Daniel-Constantin Mierla 18 Dec '23

18 Dec '23

Hello, a short announcement to inform that the dates for next Kamailio World Conference have been set to April 18-19, 2024, the event to take place again in Berlin, Germany. It will be a different venue than the past editions, that one not being available. A pre-conference day is considered on April 17, 2024, but it is not yet known in what form and where. The conference is scheduled a bit earlier than the usual in the year because Germany hosts the Euro 2024 football championship during June-July 2024, making May very busy and harder to find adequate conferencing space in Berlin. The website and more details will be published soon.

Regretfully we were unable to process the URI
by Gavin Baumanis 18 Dec '23

18 Dec '23

Hi Everyone, Very new to SIP And to Kamailio Configuration / administration. I have a working AWS instance with Kamailio installed on it - and it works fine. We are creating a whole new environment and I have cloned the existing AWS EC2 instances. I have edited all the configs to ensure that they are using the correct DNS names and / or IP addresses. Otherwise the "configs" are identical. While attempting to call a SIP number, I get the following message, returned to the soft phone I am using (microSIP) *Regretfully we were unable to process the URI (479/SL)* I can also see the same error message in the console of the Kamailio server. I am hoping that this might mean something to someone enough - to suggest some troubleshooting steps, please. Thanks;

Proxy Inactivity and Kamailio Log Disruption Issue.
by satyaprakash ch 12 Dec '23

12 Dec '23

HI, Scenario: We possess 2 proxies and 2 registrar servers equipped with dmq functionality. Unexpectedly, one of the Proxy IP addresses was marked as inactive (FLAG: IP) in the dispatcher list, causing the proxy to cease responding. Simultaneously, Kamailio logs stopped recording any activity. Upon restarting the Kamailio service, the problem was resolved, and the proxy resumed normal operation, with the Flag changing back to AP (ACTIVE). The sudden occurrence of this issue is not clear, and due to the cessation of logs during the incident, we lack information for the investigation. Any suggestions on how to address this issue would be appreciated. And is this scenario happened to any one in your experience?

usrloc ka_mode - Flooding OPTIONS at same time?
by Benoit Panizzon 12 Dec '23

12 Dec '23

Hi We have reached 20000 registered CPE and start facing issues. Am I observing correctly that when ka_mode 4 is enabled, OPTIONS are send simultaneously to all registered CPE and not spread over the interval? They could be the cause very high pps peaks on network equipment? If so, is there a way to spread the ka options over time so they don't cause such high peaks? Or even better, is there a way to enable them for only some customers via a variable?

is_method_f(): cannot parse cseq header in xhttp:request event route?
by Benoît Panizzon 12 Dec '23

12 Dec '23

Hi all I use event_route[xhttp:request] on Kamailio 5.5 Every time a xhttp request is processed I get this log entry: ERROR: textops [textops.c:3541]: is_method_f(): cannot parse cseq header Almost identical config on Kamailio 5.6 does not show this error. Is that something that got fixed in 5.6? I see a change in the documentation, While 5.5 does not state $rm can be accessed, 5.6 states $rm contains the HTTP method. Or do I somehow leak the http request to somewhere I call is_method() on it after terminating the event route? How should the event_route[xhttp:request] properly be terminated? With 'return' or with 'exit'? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Upgrade Minor versions
by Gavin Baumanis 11 Dec '23

11 Dec '23

Hi there, I have taken over a project that uses Kamailio. I am aware of what we use it for - I am just not sure on the how... apart from what I have read in the docs. We're currently running 5.4.2 and I'd like to upgrade to (at least) the latest 5.4 offering - as that seems as if it would be the easiest and safest option. So I am hoping I might get some direction, please - on the way forward for an upgrade. The documentation seems OK if you're upgrading minor versions... but I couldn;t find anything about upgrading patch versions. Thanks!

Hello, we should consider an online devel meeting sometime soon to summarize what was done at (and still needs to be done after) devel meeting in Dusseldorf and plan a bit the targets for next major release (5.8 or 6.0)?

Topics to be discussed can be added at: - https://github.com/kamailio/kamailio-wiki/blob/main/docs/devel/irc-meetings… Pull requests can be made by users without git access. Cheers, Daniel PS: Previous announcement indicated the start time 14:30 UTC, this message changes it to 15:00 UTC - 30min later due to a constraint in availability of one of the Kamailio developers. -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda

Setting up Kamailio as SIP Proxy
by Saul Ibarra 04 Dec '23

04 Dec '23

Hi, I am needing some help setting up kamailio as a sip proxy between a provider(trunk) and a test pbx The trunk requires username&password and i would like to add that information to the request within the Kamailio proxy, so that the PBX can authenticate directly by IP (without username&password) through the Kamailio proxy. As a programmer with a limited background in SIP (currently learning), I am keen on understanding the intricacies of this setup at the SIP level. Could you please direct me to resources or documentation that covers scenarios similar to mine? Any help or guidance you could provide would be greatly appreciated. Thanks

tsilo dependency on usrloc
by Alex Balashov 03 Dec '23

03 Dec '23

Hi, I wanted to revisit the topic of tsilo dependence on the location service. All three ts_append*() functions have the following quality: - ts_append(): "performing a contact lookup on the table specified by the domain parameter." - ts_append_by_contact(): "the contact lookup is performed" - ts_append_to(): "performing a contacts lookup on the table specified by the domain parameter" Why is this extensive coupling to usrloc necessary? This makes it impossible to use `tsilo` in case of providing a push-notification add-on that front-ends an upstream registrar, requiring a kind of local shadow registrar or mid-registrar. What would make more sense is a generic mechanism that allows one to "drip" new contacts into an existing transaction, whether suspended or active. Kamailio has a mechanism to add more branches to an existing transaction, but the scope of that mechanism is only from *inside* the vantage point of the transaction in question. The key parlour trick of `tsilo` is that it permits dripping new branches into a *different* transaction. ts_append_to() almost does the trick, providing a target index and label, but it just insists on doing a registrar lookup to source the contacts. What is really wanted and needed for the downstream PN gateway use-case is a means of extracting contacts from incoming registrations (or other sources, potentially) without storing them in any fashion locally, without using or even loading usrloc, and just throwing them over the fence into a different transaction. Is this somehow possible by means other than tsilo? Am I overlooking something?

Unable to use db_alias_lookup to call multiple extensions
by Merul Patel, PhD 01 Dec '23

01 Dec '23

Hi, Kamailio newby here. Having some trouble with using alias_db to forward an incoming call to two extensions. Thanks in advance for any help. I've tried using the Ubuntu Jammy ARM64 packages, as well as compiling the source for version 5.7.3. In both cases, I've added three extensions, and calls directly between them work fine with the vanilla kamailio.cfg. However, I then wanted to add an alias so that when called it would dial two extensions, but only the first extension is ever called. My kamailio.cfg only differs in a few places: $ diff kamailio.cfg kamailio.cfg.original 3,6d2 < #!define WITH_AUTH 1 < #!define WITH_DEBUG 1 < #!define WITH_ALIASDB 1 < # 268,270d263 < loadmodule "db_sqlite.so" < #!define DBURL "sqlite:///usr/local/kamailio-devel/etc/kamailio/kamailio.sqlite" < 367c360 < modparam("tm", "failure_reply_mode", 0) --- > modparam("tm", "failure_reply_mode", 3) 450d442 < modparam("alias_db", "append_branches", 1) I can see from the log that when dialling the desired alias (5000) an alias_db query is performed: Dec 01 20:00:23 merrivale /usr/local/kamailio-devel/sbin/kamailio[3264]: DEBUG: {1 2 INVITE 651794328853009-230332414159388(a)192.168.17.145} alias_db [alookup.c:169]: alias_db_query(): new URI [0] is [sip:6002@merrivale.localdomain] Dec 01 20:00:23 merrivale /usr/local/kamailio-devel/sbin/kamailio[3264]: DEBUG: {1 2 INVITE 651794328853009-230332414159388(a)192.168.17.145} alias_db [alookup.c:169]: alias_db_query(): new URI [1] is [sip:6001@merrivale.localdomain] But only the first result is called. I've changed the order of the aliases in the sqlite db and just the first result is called. What am I missing? Merul

How to use: kamcmd ul.db_users?

Hi List I want to find a way to check how many users are regsitered. https://www.kamailio.org/docs/modules/devel/modules/usrloc.html#usrloc.r.db… But no matter how I try, I get a 500 error... # kamcmd ul.db_users location And yes, the table is called 'location'. I did try to find out how kamctl ul show --brief pulls that information, but did not succeed. Also that command takes way too long how that we have several thousand registered users.

Hi, I have a timer which is called each 5 seconds: modparam("timer", "declare_timer", "REFRESH_CALLSTATE_TIMER=REFRESH_CALLSTATE_TIMER,5000,slow"); I'm enabling setting the variable "testvar" and enabling the timer when an INVITE is received: if (is_method("INVITE|ACK|UPDATE|CANCEL|BYE")) { $var(testvar) = "blablabla"; timer_enable("REFRESH_CALLSTATE_TIMER", "1"); ... route[REFRESH_CALLSTATE_TIMER] { xlog("L_INFO", "Testvariable: $var(test)\n"); } However, the variable is always 0: INFO: <script>: Testvariable: 0 I've also tried printing pseudovariables like $ci, $du but nothinh seems accessible. Is there a workaround for this? Best regards, Dries

Evapi Async - suspend transaction for a limited time
by Ilie Soltanici 29 Nov '23

29 Nov '23

Hello, I'm trying to use the evapi_async_relay function from the evapi module, however,I don't want the transaction to be suspended for more than 1 second. For instance, if there's no response from the external application within this time frame, I want the script to continue and remove that transaction from memory. One potential approach I am considering is to add suspended transactions to a hash table with a timestamp value. Then, using rtimer module, I could periodically parse this table every second and process the results, but I'm not sure how efficient is that. Maybe you know other alternative, more efficient solutions (from a performance point of view) that could achieve the same goal? Any insights or recommendations would be greatly appreciated. Thank you.

5.6.4 debian htable dbmode=1 not writing at shutdown
by Bernd Krueger-Knauber 29 Nov '23

29 Nov '23

Hi, I have still the problem that my htables are not written into a sqlite db when I shutdown kamailio. Manual writing via: kamcmd htable.store ... is working. As I can see in the logs with highest loglevel, the function destroy() is never called. ht_db_url.len is > 0 ht_db_init_con() should work, else nothing would work with the db. But I can not see the debug messages from ht_db_open_con() Any ideas? Best regards, Bernd

Incompatibility of the DMQ htable protocol with older Kamailio versions
by Denys Pozniak 29 Nov '23

29 Nov '23

Hello! I noticed that there are differences in the DMQ htable replication protocol for the old version of Kamailio 5.2 and the new 5.7. For example, the new version uses action 2 when updating values and action 4 to remove. The old Kamailio version uses the values 1 and 3 respectively. Well, as a result, the htable data is not shared between such nodes, plus there are errors in the syslog of the old version: ERROR: htable [ht_dmq.c:328]: ht_dmq_handle_msg(): failed to replay action It would probably be worth introducing some kind of DMQ htable protocol versioning to maintain compatibility? And is there any option to make them work together (I wouldn’t really want to change the action number in sip/sdp/json on the fly)? Kamialio 5.2 {"action":1,"htname":"shared","cname":"user","type":2,"strval":"uri","mode":1} {"action":3,"htname":"shared","cname":"user","mode":0} Kamailio 5.7 {"action":2,"htname":"shared","cname":"user","type":2,"strval":"uri","mode":1} {"action":4,"htname":"shared","cname":"user","mode":0} -- BR, Denys Pozniak

tps_storage_fill_contact(): no r-uri user
by Denys Pozniak 28 Nov '23

28 Nov '23

Hello! My topology is like this: PBX -> Kamailio Topos -> User When calling the user, PBX does not add the user part in the Contact URI, something like: Contact: <sip:10.10.10.10:5080;transport=udp> When the customer sends a reinvite, the topos turns off for this transaction and the sip partially breaks down with error: topos [tps_storage.c:319]: tps_storage_fill_contact(): no r-uri user topos [tps_storage.c:615]: tps_storage_record(): failed to store As far as I understand, the RFC allows the absence of the user part in the URI and this occurs quite often. I can provide the pcap file and debug log in a private message if this helps identify the essence of the problem. # kamailio -v version: kamailio 5.7.1 (x86_64/linux) 1cf389-dirty -- BR, Denys Pozniak
