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 … [View More]

TCP core parameters and TLS
by Alex Balashov 22 Apr '18

22 Apr '18

Hi, Is it reasonable to assume that the various tcp_* core parameters (keepalive behaviour, connection limits, buffer sizes, etc.) also regulate the behaviour of TLS connections, since TLS is encapsulated in TCP? -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

CLID blacklist
by Nelson Migliaro 21 Apr '18

21 Apr '18

Hello, I am looking for a module to block number based on CLID. If the module allows REG expresions it would really make my day. I need to block some callers and I would like to use a module and database to avoid restarting kamailio service everytime a new number appears. Thank you Nelson.-

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. 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. Now it is reproduced constantly, but on some machines.

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 … [View More]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 … [View More]

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 … [View More]
