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. Thanks, Kiran

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
