Configuration script behaviour with http_async_client usage
by Kris Domagalski 29 Oct '21

29 Oct '21

Hi, I'm new in Kamailio and looking for some configuration guidance. I'm using http_async_client for API requests. It's configured to use TEST2 route, which should be executed upon reception of HTTPS response. After receiving the response I would like to go back to the request_route and perform some more actions. Currently behaviour is, in the syslog I can see only entries which I push from TEST2 route (TEST 123). Cannot see the one from request route. Current syslog output: TEST123 … [View More]

Re: [SR-Users] No "child_destroy" export - issue with module flatstore and flush=0
by Chaigneau, Nicolas 29 Oct '21

29 Oct '21

Hello Henning, Thanks for your reply ! For the record, I'm using Kamailio module "flatstore" with the flush deactivated. In this situation, when Kamailio is stopped, I'm losing the remaining data in files not yet flushed. So my idea was, when destroy is called, to iterate over the connection pools, and flush/close all the opened files properly. But I found out that it's not that simple :/ Do you think this is something that could be fixed in Kamailio ? Regards, Nicolas. De : Henning … [View More]

Does failure_route for redirection covers all error cases ?
by Liviu ANDRON 29 Oct '21

29 Oct '21

Hello, We are routing calls to FreeSWITCH servers. We have a failure routing mechanism in place, which looks pretty common from my research around: route[INVITE] { ... t_on_failure("REROUTE"); and failure_route[REROUTE] { if (t_is_canceled()) { exit; } // also 6xx ? if (t_check_status("5[0-9][0-9]") or (t_branch_timeout() and !t_branch_replied())) { // re-route to another available FreeSWITCH server } } The problem is that we don't capture all the failures … [View More]

t_relay changing source IP?
by Brooks Bridges 27 Oct '21

27 Oct '21

So we have a box that's bound to all interfaces on the server, and one specific IP address (that is an HA IP), and I've run into a bit of an odd behavior that I cannot explain. For 99.9999% of our traffic, the invites come into the HA IP, and then are forwareded out the HA IP to an SBC for further processing. In a very rare instance however, I have found that there is an invite coming in the HA IP, and for some unknown reason it gets forwarded out the *interface* ip instead of the HA IP.

Use constants in attrs column of the dispatcher module
by Markus Bönke 27 Oct '21

27 Oct '21

Hello all, I’ve a question regarding the dispatcher module. So far we use on every server a separate database table, where the attribute column is set to the local internal or external socket like "socket=udp:192.168.1.70:5060“ or socket=udp:80.239.xxx.xxx:5060. Is there a way to use constants here like socket=udp:IPADDR_INTERN:5060 or socket=udp:IPADDR_EXTERN:5060 which are replaced when the data is loaded from the DB? Thanks and regards Markus

Hi, We're currently implementing WebRTC (SIP over a websocket) on our Kamailio proxies and we're experiencing a minor issue after a restart.

Routing dialogs (INVITE) from Lua

So I've been working on this for a while, and I cannot seem to find a way around this. When using the http_async_client to request data from an external API, the returned data in the "route_name" target is being treated as a failure route, so most of the subsequent processing and messaging that I want to do is not working, either because the function can't be used in a failure route, or because I have to create a transaction prior to doing the request, which then throws an error by immediately … [View More]

Let's Encrypt DST Root CA X3 cert CA expiration 30th/Sept - Any issues?

Hello, I'm wondering if anyone had any issues yesterday with the expiration of the DST Root CA X3 cert? Out of all the servers I manage, only a couple were affected (debian 8). They were production servers so we replaced the cert with a different one to solve the issue while we find the root cause. Anyone out there had any issues yesterday because of this? I'm just curious!

rtpengine module dependencies
by Juha Heinanen 10 Oct '21

10 Oct '21

rtpengine module README tells this about module dependencies: 3.1. Kamailio Modules The following modules must be loaded before this module: tm module - (optional) if you want to have rtpengine_manage() fully functional Looks like this is not correct. If Kamailio connects to rtpengine over websocket protocol, then there is dependency on lwsc module. I haven't checked if lwsc module works without tls module when wss is used. -- Juha

update max_while_loops in config
by Juha Heinanen 08 Oct '21

It is possible to update value of max_while_loops dynamically in config file? For example, there could be a need to increase the max in some while loop, but after the loop is done, decrease it again for other loops. There exists an rpc command to do that, but I haven't found how to do it in config file. I tried @cfg_seti.core.max_while_loops = 200; but got syntax error. -- Juha

ACK not accepted

UAC is behind NAT with LAN IP 192.168.1.105 and Public 200.200.200.30 Carrier IP 50.50.50.19, Kamailio1 IP 100.100.100.243, Kamailio2 IP 100.100.100.210 The Carrier sends in a new call and the call is answered from the UAC with 200 OK SDP. Carrier sends ACK and it looks like it reaches the … [View More]UAC but, UAC still resends several times 200 OK and carrier sends server ACK that arrives or not ??? to UAC until finally UAC sends a BYE. On the SIP flow you can see that Kamailio2 sends the ACK to 192.168.1.105 and not to 200.200.200.30. Is this ok?? Another thing to mention is that Kamailio2 that has the UAC connected via TLS, can be used fine from the UAC to make an outbound call following the reverse path, but on the inbound we have the below.

Querying presence state from config file
by Igor Olhovskiy 01 Oct '21

01 Oct '21

Hello! Is there any method of querying presence (dialog) state for particular endpoint from config file other than that direct query to presence tables in database? Idea is to reflect server-side DND state as "confirmed" (talking) , so I need to skip certain PUBLISH messages not to reset this state. -- Best regards, Igor

I have an existing kamailio 4.4 - rtpproxy running and I get the config files from both and setup the new vm. Just private connection works but the idea is to have connection from outside too. I am sure there is a mismatch with public ip, natting and/or setup of the vm hosts file. - architecture: *- 1x virtualbox* + 1x vm with bridge mode for network (… [View More]get private ip address from the router).

RTPEngine + Kamailio state question
by Alex Balashov 30 Sep '21

30 Sep '21

Hi, Sorry if I missed any developments on this, but: Kamailio does keep a runtime association of Call-ID+Ftag => RTPEngine instance, which is significant if an RTPEngine set with multiple members is used, or if a non-default set is used for a given call. When Kamailio is restarted, this runtime association goes away, so any subsequent offer/answer cycles or any other commands will (maybe) go to the wrong RTPEngine and/or the wrong set. Last time I checked a few years ago, there was no … [View More]

Sipwise SEMS

Hello guys, I know SEMS can provide conference, voicemail, and other services. In theory it’s also a B2BUA. Could I use a python script to provide a simple routing service? I.e.: receive an invite and send it somewhere else based on some routing logic? Thanks all David -- Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

using LDAP as database ?
by Volker Denneberg 28 Sep '21

28 Sep '21

Hi, I am searching for a setup where phones register at a central kamailio and kamailio shares these contact infos with multiple asterisks. So they all need to share a database. For redundancy reasons, the database should work across 2 datacenters. As far as 1 understood there are some options * use mysql - good chances to find example code, Siremis API, seems to be the standard solution * use redis - more performant than mysql * use ldap - good chances to integrate with existing … [View More]

siptrace & topos modules on 5.3
by Angelo Sipper 24 Sep '21

24 Sep '21

Hi, We are using kamailio 5.3 latest version with the topos module. We have added Homer 7 latest version to consolidate traces from all kamailios and we have enabled siptrace module on kamailio to send data to homer. What we have seen up today is that traces on homer have sip headers before topos changes. So if I look at the same call on sngrep on the kamailio machine, I see the correct topos changed headers. If I check the same call on Homer I see headers without topos changes. Also we get … [View More]
