how to disable sip authentication
by BIPIN KUMAR Das 02 May '18

02 May '18

Hi, Is there any way in Kamailio where I can suppress sip registration authentication. I want, Kamailio can send 200 OK for sip registration without going for 401 Unauthorized. Please tell me if you have such configuration in Kamailio. thanks Bipin

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

Hello The list, What do you think of the purpose of this function Nat_Uac_test('16') 16 - Test if the source port is different from the port in the "Via" header Correct me if I'm wrong but compare the source port of the message with the source port of the via is only valid on the initial invite ? All subsequent messages or replies don't list the UAC anywhere in the via. Thanks for your replies,

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!

Hello all last March 26th we experienced a crash on a 5.0.1 kamailio server and a core was generated.

it crashed. here you have the backtrace <154>Mar 26 19:54:03 mad-proxy-inout-1 /usr/local/kamailio/sbin/kamailio[24992]: : <core> [core/mem/q_malloc.c:469]: qm_free(): BUG: qm_free: bad pointer

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

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.

UAC with HA1
by Ben Hood 24 Apr '18

24 Apr '18

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
