MSILO: Message limit on SIP stored offline MESSAGE delivery
by Abdul Basit 04 May '18

04 May '18

Hi Team, I have setup IM server with kamailio using MSILO module. Its working fine now. I have a scenario where lot of offline messages are being stored in mysql database for a user B. As soon as destination (B) REGISTER with kamailio, these messages will deliver to him. Now, kamailio will deliver all of these messages that will cause user (B) device (softphone on mobile) stuck or freezs for the moment messages are being delivered like bombardment from kamailio. Is there any way, where I can define batch size of messages to be delivered after provided interval? like batch_size=10 messages and batch_interval= 5sec, etc. I want to avoid applying static limit to mysql query in module source code. Please advise. -- regards, abdul basit | p: +92 32 1416 4196 | o: +92 30 0841 1445

Hi, can I with keepalive module ping with is_alive function endpoints connected to kamailio? Or this module can use only static destionations via modparam("keepalive", "destination", "sip.provider.com")? -- Aydar A. Kamalov

Relay Latency
by Daniel Greenwald 03 May '18

03 May '18

We are using kamailio 5.0 as an inbound dispatcher. Sometimes in testing we see it take over half a second to relay a 200 OK. The logs show the new dialog being creating for the 200 OK within .0001 seconds of receiving the inbound 200 but it takes another .5 seconds for the relayed 200 to actually hit the wire. Here is a screenshot showing the timing of the packets. The box is an EC2 m3.medium under almost zero load (1-2 calls). Is this normal? What should I be looking at? Screenshot below: 10.0.23.34 is the kamailio box. Carrier IP obfuscated. You can see the carrier resends the 200 OK because of the delay.

Kamailio with dispatcher not send BYE to Asterisk.
by Jeferson Oliveira 03 May '18

03 May '18

Hello everyone, I have an error that I have not yet been able to solve and would like the help of colleagues to indicate a correct path. The problem that is occurring is that when the client disconnects the call kamailio is not sending the BYE forward until arriving at the asterisk. Both in the test scenario and in the production scenario the problem is the same and the message I see in the capture is 404 Not here, msg this coming from kamailio. Production scenario. PSTN <----------> Dialer --------->kamailio -----------> asterisk1 -----------> asterisk2 Test scenario. sipp generated calls ------> kamailio -------> asterisk1 -------> asterisk2 When this occurs, the calls that are disconnected by the client are in a "zombie" state in asterisk, and end up being terminated by timeout with the following message in the asterisk CLI: /[Apr 25 17:49:59] WARNING[2121]: chan_sip.c:4072 retrans_pkt: Retransmission timeout reached on transmission 22-6073(a)10.110.7.242 for seqno 1 (Critical Response) -- See https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions// //Packet timed out after 31999ms with no response/ In the sipp panel I see in the Retransmission column several incrementing counters, as per the attachment. If I take the kamailio from the move and point the sipp to only one of the asterisk, the retransmissions do not happen and BYE follows normally. My kamailio.cfg configuration file can be downloaded from this url: https://drive.google.com/file/d/1bBj4GEZSPrp1iJXSLWQ4Z6g59tEFjnNT/view?usp=… Thank you very much. --

Record-Route and received/rport parameters
by Asgaroth 03 May '18

03 May '18

Hi All, I've come accros a scenario where a proxy is sitting on a private address range and inserts a record-route specifying the the private address. This causes issues whereby the BYE to an INVITE attempts to relay to the private address defined in record-route. I was wondering, if we were inject a received and rport parameter into the record-route header of the original invite, whould kamailio relay the response (BYE) to the receive/rport destination instead of the uri defined in the record-route header. As an example, initial invite comes in with a record-route as follows: Record-Route: <sip:172.17.0.2:5062;lr;ftag=b4551d29> If we injected received and rport as follows: Record-Route: <sip:172.17.0.2:5062;lr;ftag=b4551d29;rport=33429;received=212.172.2.212> and relayed the message to the B2B. Then, I assume, when the B2B creates its BYE message, the Route header should look like this: Route: <sip:172.17.0.2:5062;lr;ftag=b4551d29;rport=33429;received=212.172.2.212> Once this hits the kamailio instance to relay to the last route header as mentioned above, would it set $du to received:rport like it does with Via headers? Thanks

DMQ and/or Database for dialogs, registrations, etc..
by Joel Serrano 03 May '18

03 May '18

Hi all, Just wanted to know what your opinions were on using DMQ modules over database for things like dialog replication, registrations, etc... Is DMQ the "new way to go"? I know that there lots of ways of doing things with each having pros/cons... But I was wondering... What does the community think on this topic? Are you guys taking advantage of the DMQ modules or are you still relying on database as much as possible? Maybe a combination of both? Cheers, Joel.

Kamailio config file String Concatenation
by George Diamantopoulos 02 May '18

02 May '18

Hello, I'm a a bit confused as to when string concatenation will work in kamailio config file. So far I have identified the following cases: Working: As part of the right hand side of an assignment: $var(x) = "string1" + "string2"; String argument of some functions: xlog("L_ERR", "string1" + "string2" + DEFINED_STRING + '\n'); Conditional Statements: if ( ru =~ "$" + "sip:" + $var(user) ) { Not Working: In string transformations (the fact that quotes is not part of the argument should give a hint though: $var(x) = $(var(y){s.replace,match,"repl1" + "repl2"}); String argument of some other functions: append_hf_value("P-Asserted-Identity", "<" + "$var(new_pai)" + ">"); lookup("location", "sip:$var(username)@" + SIP_REALM_DEFINITION)); In module parameter definitions: modparam("nathelper", "sipping_from", "sip:keepalive@" + SIP_REALM_DEFINITION) So far, I have found this to be fairly consistent, except for use within functions. For example, string concatenation works for the second argument of xlog, but not for the string arguments of append_hf_value() or lookup(). Is there anyway to know this for each function beforehand, or is my only choice to go through trial and error here? Thanks! BR, George

Routing 10 Digit Inbound call to Registered User or VM server
by KamDev Essa 02 May '18

02 May '18

I have Kamailio 5.1 installed and running with 2 extensions, 201 and 202 registered. Both extensions can call each other perfectly. Next I am workin on inbound calls. I have an inbound call from a carrier that arrives perfectly but ends up in this area of the cfg case -3: send_reply("404", "Not Found"); exit; and sends a 404 not found. How do I : - Associate the 10 digit DID to the 201 or 202? Custom table I make or is there something native to Kamailio. - Relay the call to the 201 or 202. Thank in advance KamDev

Auto 100 Reply
by Duarte Rocha 02 May '18

02 May '18

Greetings, I have set the auto_inv_100() parameter from the TM module so i can get automatic "100" replies to the INVITE. However, in some cases i want to reply to the INVITE with provisional responses (181 for example) and i would like that "100" could be sent before the "181". In order to achieve this, on transactions that are going to be replied with 181 i'm turning off the parameter with t_set_auto_inv(0) and the sl_send_reply("100","Trying"). Is this the best way to do this? Thanks

Send UPDATE to inform changes in SDP
by Alfonso Pinto 30 Apr '18

30 Apr '18

Hi guys, I'm trying to setup a Call Forward No Reply with Kamailio and I've run into this problem (that was expected): When A INVITEs B, B replies with 183 and some SDP. B doesn't answer so Kamailio triggers the timeout and sends the INVITE TO C. C replies with 200 OK and some SDP, but A side drops the call as the media session doesn't match with the expected one. To solve it, I'm trying to send to A an UPDATE before relaying the 200 OK from C. I tried to use UAC module (uac_req_send + $uac_req) but I don't see how I can UPDATE the existing dialog. uac_req_send seems to try to setup a new dialog always. Is there a way to indicate to uac_req_send that I wan't to use the existing dialog? Or maybe there is another mechanism I can use to send the UPDATE inside the dialog? Regards, Alfonso.

nathelper issues
by Konstantin Polyakov 29 Apr '18

29 Apr '18

Hello All, Unfortunately we found two more bugs in the nathelper module in my favorite Kamailio! Oh my god! 1. nathelper doesn't send pings when db_mode=3 and db is mongodb. I will provide fix soon. The root cause is incorrect date format in get_all_db_ucontacts function in usrloc. We need to use datatime type instead string. 2. nathelper doesn't send pings if ping_nated_only=0 (default value). It looks like incorrect condition in nh_timer in nathelper. Definitely lack of testing. It is interesting how testing is organized in the Kamailio community? Best regards. Konstantin ping_nated_only

User agent is registered but location table doesn't contain its contact.
by Konstantin Polyakov 28 Apr '18

28 Apr '18

Hello All, Hello Daniel! We have met a new issue. We use db_mode=1 ( Write-Through scheme. All changes to usrloc are immediately reflected in database too ). timer_interval has default value 60 seconds. Problem description. Some user agent is registered successfully in Kamailio registrar. Its contact exists inside internal cache (ul.lookup command shows it). But location table doesn't contain this contact. After several minutes (5-6 min) it becomes available in the location table too. The issue is reproduced periodically. Most of the time everything is ok. Is that expected behavior when internal cache is used? Did somebody else observed such situation? Is there some workaround? Best regards Konstantin

Sending Notify With Custom Event Header
by strain17 27 Apr '18

27 Apr '18

Hi All, I'm trying to send a custom NOTIFY message to a list of users that are registered with Kamailio. The procedure would be invoked via HTTP (jsonrpc/xmlrpc over HTTP). 1. Should I be looking at the t_uac_start/t_uac_dlg MI commands to accomplish this? Is this the best way to do it if the NOTIFY sent to the phones are unsolicited? 2. I tried to use the xhttp_rpc module for testing out tm.t_uac_start but kept running into 400 invalid headers. I'm not sure if there is a syntax issue. The NOTIFY example is NOTIFY sip:123@192.168.5.5 . . From:333@1.1..1\r\nTo:test@2.2.2.2 - Request URL: http://x.x.x.x/http_rpc/tm/tm.t_uac_start?arg=NOTIFY+sip%3A123%40192.168.5.… - Request Method: GET - Status Code: 400 Invalid headers Thanks for any feedback!

Possibility of kemi lua to keep lua global vars
by Yuriy Gorlichenko 26 Apr '18

26 Apr '18

Hi For now as I see: every request that calls lua script reevables my global lua variables For example I trying to connect to DB via luasql driver and checking if connection already existis to avoid new connection I have function init() that calls in ksr_request_route() Inside i have ome check: if not CON then CON = assert(MYSQL:connect(DBdata.dbname,DBdata.username,DBdata.password,DBdata.host,DBdata.port)) if not CON then KSR.log("info","|init|log| DB NOT connected\n") KSR.sl.sl_send_reply(503,"Internal server error") KSR.x.exit() else KSR.log("info","|init|log| DB connected\n") end end So in this case if CON was already created it should not try to connect But for now it tries for every request. So means kemi not stores global lua variables between sessions (in one kamailio process) Also as I know INIT routes initiates before lua machine will be started so it not allowed to init some lua global variables in the init routes So my question is there is a way to keep global vars per kamailio process instead per kamailio request?

Sha2 self-signed certs config in Kamilio
by Kiran Gaddam 25 Apr '18

25 Apr '18

Hello All, I want to enable certificate validation on the server. I am only using self-signed certs. I have the same cert/key in the client and server and want to only allow connection from clients with this cert/key. I have turned on the following in tls.cfg and done all the steps required in kamailio.cfg file. But it's failed to verify certs and allowing the clients which doesn't have same certs. Please help to configure the cert/key in right way. [server:default] method = TLSv1 verify_certificate = yes require_certificate = yes private_key = /usr/local/etc/kamailio/selfsigned.key certificate = /usr/local/etc/kamailio/selfsigned.pem ca_list = /usr/local/etc/sip-router/cacert.pem [client:default] verify_certificate = yes require_certificate = yes In advance Thank you.

TCP packet relay delayed (Kamailio 4.1.5)
by Andrew Chen 24 Apr '18

24 Apr '18

Hi Kamailio community, I need your urgent help regarding a situation where the Kamailio TCP packet delayed in relaying SIP packets. They delay between the time Kamailio logs the relay to the time it left the system was ~20 seconds difference, which is huge in SIP world. Any ideas, thoughts or suggestions on how I can narrow down to the problem? We have about 30 cases of this today Thanks in advance. -- Andy Chen Sr. Telephony Lead Engineer achen@ <achen(a)thinkingphones.com>fuze.com -- *Confidentiality Notice: The information contained in this e-mail and any attachments may be confidential.

Diversion Headers
by Duarte Rocha 24 Apr '18

24 Apr '18

Greetings, Does the function "add_diversion() present in the "Diversion" module allows me to introduce other parameters (privacy, counter, etc) or is it only for the "diversion-reason"? If it doesn't let me do that, how can I add the Diversion with insert_hf() and make sure the headers are added in the right order? Cheers

Any ideas on how to implement prepaid calling function which is persistent after restart
by Kit Lim 24 Apr '18

24 Apr '18

Hi Everyone, My project involves keeping track of the allowable duration for the caller to talk, and keeping track of the status of the call with the back end database. Currently i have implemented using the following modules (aside from the default modules in the sample config script). * http_async_client.so - to communicate with the backend DB * dialog.so - mainly use to detect the 200 ok answer in relation to invite, and the end of the call * cnxcc.so - to release the call when the allowable talk time is reached The flow is as below:- Invite -- > http to backend DB to ask for talk time <-- DB returns value 200 ok (answer) ---> http backend DB to update that the call has answered <-- DB returns ok dialog end or Cnxcc terminate --> http backend DB to update that the call has hangup My problem is that if there is a need to restart the kamailio config there is no 'graceful' way to hangup all the calls and inform the backend, or deny any new calls from coming in. If kamailio is restarted then cnxcc would have forgotten that there is a maximum talk time allowed to be called or recover from the restart. How to I make the system resilience to failures/restarts. Appreciate any good suggestions. regards CK

Re: [SR-Users] Kamailio doesn't start with db_mongodb and usrloc.
by Konstantin Polyakov 24 Apr '18

24 Apr '18

Dear All, It looks like there is a serious error inside db_mongodb module in the latest versions of Kamailio 4.4.7 and 5.1.2. During query operations string fields inside result structure db1_res_t could be corrupted because of incorrect usage of bson memory. The issue is located in the function db_mongodb_convert_bson() around line 614. This issue is reproduced when we need to read more than 150 documents from the database. So that is why this issue still exists. Firstly bson_iter_utf8 function returns pointer to memory which is allocated inside bson memory and which is used multiple times. So the data must be copied into Kamailio memory instead storing that pointer. The pointer becomes invalid after some time. Secondly, this pointer must not be freed by the caller of bson_iter_utf8 . At the current version bson allocated pointer is freed by Kamailio function pkg_free like it is was allocated by pkg_malloc . So I am going to create ticket in the github and propose the fix. It looks like nobody uses mongodb with Kamailio in db_mode=1 :) Best regards Konstantin >---------------------------------------------------------------------- > >Message: 1 >Date: Sat, 21 Apr 2018 23:37:26 +0300 >From: Konstantin Polyakov < piligrim_pk(a)mail.ru > >To: sr-users(a)lists.kamailio.org >Subject: [SR-Users] Kamailio doesn't start with db_mongodb and usrloc. >Message-ID: < 1524343046.238272820(a)f356.i.mail.ru > >Content-Type: text/plain; charset="utf-8" > > >Hello! > >Similar issue but with different symptoms. > >kamailio 4.4.7 (tried to use db_mongodb module from 5.1.2) >usrloc is configured to use db_mode=1 and db_insert_null=1. > >MongoDB 3.6.3 >mongo-c-driver was tested 1.9.2 and 1.9.4. > >location table contains 300 records. > >The issue was not reproduced since February when we started a new feature.

Hi, Does the UAC module support ha1 passwords for the remote registrar? The DDL for the uacreg table indicates the might be the case, but it’s unclear which one the UAC module would use by default. Is there a parameter to set this? Cheers, Ben

Kamailio not listening to proper ipv6 address
by selak Dev 23 Apr '18

23 Apr '18

Hi, I need to enable Kamailio to work with ipv6 also, and I enabled auto_bind_ipv6=1 and when restarted I can see that it is listening to ipv6 ip addresses also. The problem is that it stripped the ip address at the end and it is listening to the wrong one. When I try to register I get timeout, since it is not listening the correct address. ip address of the server is 2604:a880:400:d0::yyyy:xxxx and when I execute "sudo netstat -plnt" too see which app is listening to which address/port I can see: .... tcp6 0 0 2604:a880:400:d0:::5085 :::* LISTEN 17748/kamailio tcp6 0 0 2604:a880:400:d0:::5061 :::* LISTEN 17748/kamailio It somehow stripped the last part of the address (yyyy:xxxx). I dont know if it is related to :: which would be all zeros, but it doesn't work even if i explicitly specify which address to listen with listen=[2604:a880:400:d0:0000:0000:yyyy:xxxx] or listen=tcp:[2604:a880:400:d0:0000:0000:yyyy:xxxx]:5061 or listen=tcp:[2604:a880:400:d0::yyyy:xxxx]:5061 I tried all combinations and the results are always the same... Have anybody had this problem before? Do you know how to fix this? Best regards, Marko Selakovic

select outgoing interface
by Laurent Schweizer 23 Apr '18

23 Apr '18

Dear all, I have a config with multiple interface( multiple IP in same subnet) and want to know how I can select the interface used to send a request (UDP). The best is the possibility to choose for each request the outgoing interface but if it's not possible I think I can also work with a solution where the outgoing interface is defined globally ? I need this because one provider request one IP for inbound call and one IP for outbound call . Thanks Laurent

Kamailio relays ACK itself
by Volkan Oransoy 22 Apr '18

22 Apr '18

Hi all, I have a Kamailio box which I use as a uac_client. We register a bunch of accounts to remote providers. The box relays incoming calls to a FreeSwitch box. We encountered a strange problem on one account. Kamailio relays the call to my FreeSwitch box successfully but routes the ACK itself which is the reply of 200Ok. I believe this is a provider related issue but I need a technical explanation. Does anyone have any idea? Here is the packet capture: https://pastebin.com/PA8StiWY Thanks, -- Volkan Oransoy

Kamailio doesn't start with db_mongodb and usrloc.
by Konstantin Polyakov 21 Apr '18

21 Apr '18

Hello! Similar issue but with different symptoms. kamailio 4.4.7 (tried to use db_mongodb module from 5.1.2) usrloc is configured to use db_mode=1 and db_insert_null=1.

question on TM transaction matching
by Kelvin Chua 19 Apr '18

19 Apr '18

i am monitoring an issue with 5.1.2 where a cancel is not being propagated after a 183 is received the packet dump doesn't show anything anomalous. some notes: 1. the invite went out through t_relay(), transaction is tracked 2. cancel is handled this way if (is_method("CANCEL")) { xlog("CANCEL received"); if (t_check_trans()) { route(RELAY); } exit; } 3. if the UAC who is sending the call to kamailio is configured to send invite with RURI without a port i.e. 14087654321(a)w.x.y.z instead of 14087654321@w.x.y.z:6050, then this does not happen 4. can be argued that this is not an issue, and that the client should just be configured properly with outbound proxy and ruri without port. but i am just being difficult here and wanted to understand what is going on with the matching algo.

Info: Kamailio Unit Testing Framework using Docker
by Daniel-Constantin Mierla 19 Apr '18

19 Apr '18

Hello, a while ago, I started to put together a unit testing framework for Kamailio. It was more or less inspired from the old shell-based testing framework added by Henning Westerholt many years ago (which still resides in source tree path test/unit/), but now leveraging docker to have an isolated environment for running the tests. The new testing framework is available on github at: * https://github.com/kamailio/kamailio-tests Giacomo Vacca helped a bit so far, he is actually going to present more about it at Kamailio World 2018 (https://www.kamailioworld.com/k06/schedule/). But we want now to get more feedback from community, eventually to adjust the framework to become something easy to use and even more important, to be easy to contribute to. One of the main benefits from my point of view it would be to have the reports of the issues that can be reproduced submitted along with a unit test. It would make it easier to troubleshoot and then after fixing it, would be tested always before releases in order to avoid regressions. Right now, a good help from community would represent converting the old unit tests to the new framework, afterwards we can decommission test/unit. The conversion should be rather easy, as we still rely on shell and the sip tools like sipp/sipsak ... If you want to help here by you need clarifications or get stuck somewhere, just write to mailing list and I would be more than happy to assist. Such contributions should be submitted as pull requests in order to be easy to review: * https://github.com/kamailio/kamailio-tests/pulls Looking forward to your feedback, comments or contributions! Cheers, Daniel -- Daniel-Constantin Mierla www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio World Conference - May 14-16, 2018 - www.kamailioworld.com

Branching and rejects.
by Kjeld Flarup 18 Apr '18

Hello What is the correct way to handle, if a branched call reaches a 404 on one of the branches. Currently I discard all 404 in onreply_route, but if all branches has 404, then this is never send to the caller. -- -------------------- Med Liberalistiske Hilsner ---------------------- Civilingeniør, Kjeld Flarup - Mit sind er mere åbent end min tegnebog Sofienlundvej 6B, 7560 Hjerm, Tlf: 40 29 41 49 Den ikke akademiske hjemmeside for liberalismen - www.liberalismen.dk

Failure Route Issue
by mack＠dopensource.com 18 Apr '18

18 Apr '18

Hey All, I have a weird issue. I’m sending a SIP INVITE to a SIP Service that send’s me back a 433, which let’s me know that the number is invalid. I then send an INVITE to a media server (FreeSwitch) to play a message that the number can’t be called, which looks to be working. But, the final ACK from the SIP client is sent back to the SIP Service versus the media server. The following diagram below depicts this: https://snag.gy/qMWfvk.jpg. The code snippet in the failure_route for the the SIP Service has this: if (t_check_status("403|433")) { if ($avp(s:teleblock_media_enabled) == "1") { # make sure media server can route back to kamailio record_route(); revert_uri(); $ru = "sip:" + $T_reply_code + $rU + "@" + $sel(cfg_get.teleblock.media_ip) + ":" + $sel(cfg_get.teleblock.media_port); append_branch(); t_relay(); exit; }

Kamailio Websocket Questions
by Nagorny, Dimitry 17 Apr '18

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.
