Problem connecting to Redis DB using DB_REDIS module with a Password
by Nick Digalakis 08 Aug '23

08 Aug '23

Hello everyone! I had a Kamailio 5.6.4 server using the DB_REDIS module for quite some time without a password on the Redis DB working just fine. A few days ago I decided to add a password to Redis and modify the Kamailio config file with the following line per the documentation to be able to authenticate: modparam("db_redis", "db_pass", "r3d1sPass") Since that moment, I see the following errors in the Kamailio logs: ...... kamailio: ERROR: <core> [core/modparam.c:175]: set_mod_param_regex(): parameter <db_pass> of type <1:string> not found in module <db_redis> kamailio: CRITICAL: <core> [core/cfg.y:3790]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 556, column 49: Can't set module parameter ...... The documentation I am reading is here: https://www.kamailio.org/docs/modules/devel/modules/db_redis.html#db_redis.… Could someone help me figure out what I am doing wrong? Many thanks, Nick

Hello, On 5.6.4, i’m trying to perform mwi pua_json, but cannot get it working. I have a doubt about my json and spent some time to make variations on json without success. Does one of you played with it and can tell me if something is wrong about this json ? { "Event-Package":"message-summary", "Event-Name":"update" "expires":3600, "From":sip:ccoca@dff.com, "To":sip:ccoca@dff.com, "Message-Account":sip:ccoca@dff.com, "Messages-Waiting":"yes", "MWI-Voice-Message":"2/8 (0/0)", "Messages-New":"2", "Messages-Saved":"8", "Messages-Urgent":"0", "Messages-Urgent-Saved":"0", "From-Realm":"dff.com", "From-User":"ccoca", "Call-ID":0_845806535@10.22.22.22<mailto:0_845806535@10.22.22.22>, } Regards, David

Subscribers and peers handling
by Kiss Zoltán 08 Aug '23

08 Aug '23

Hello, We are trying to build a lightweight SBC solution for some external peers, but currently there is a mixed environment which is handled by Asterisk. We have some "peers" with IP based auth, and also some "subscribers" with register. We have succeded with the subscribers, because we can handle the numbers for those type of users with aliases in Kamailio. So basically we have a subscriber, lets call it "test", and we can add aliases for the subscriber like "3612345678@localhost", then if we are calling the number the routing goes to the contact of "test" subscriber. Currently the problem is that we dont have any idea about the IP based peers, because those peers not registering, so we cannot create aliases for them as far as i know. How do you solve this type of problem? Maybe im overcomplicating the situation, but i havent got any solutions in my mind currently. Thanks for your help and ideas. With kind regards, Zoltan

Connection to AWS services (e.g DynamoDB)
by Lewis Hutchinson 07 Aug '23

07 Aug '23

Hi Jakub Although no direct experience with this exactly as you have described I have used HTTP API out of Kamailio quite a bit and into other services. Which yes some ultimatly end in AWS> Having done our's in KEMI there is some difference however from our experience we did notice some of this didn't fair well under a loads test scenario. We tested Kafka vs Kamailio HTTP API Modules vs Aiohttp (Python in Kemi) and Kafka significantly out perfomed in terms of the load test. We then had to rejig things to account for this instead of HTTP API. If this is ever going to be under intense load. Maybe make sure you do the load testing early on before you ratify your design. Also make sure all your error habndling is in place and working to prevent issues in Kamailio if something API side goes wrong. Mission Labs Limited is registered in England, company number 10040088.

Setting up rtpengine to relay RTP
by Alvaro Escobar 05 Aug '23

Hello I have debian 11 with kamailio 5.6.4 (x86_64/linux). The kamailio is working fine. Now I need to setup rtprngine to relay RTP. I have installed the rtpengine using this guide: https://dfx.at/rtpengine/ Version: 10.5.4.3-1+b1 When I run: systemctl status rtpengine-daemon I got: ● rtpengine-daemon.service - RTP/media Proxy Daemon Loaded: loaded (/lib/systemd/system/rtpengine-daemon.service; enabled; vendor preset: enabled) Active: active (running) since Tue 2023-08-01 20:58:23 -05; 51min ago Docs: man:rtpengine(8) Process: 468 ExecStartPre=/usr/sbin/rtpengine-iptables-setup start (code=exited, status=0/SUCCESS) Main PID: 535 (rtpengine) Tasks: 22 (limit: 2323) Memory: 42.1M CPU: 720ms CGroup: /system.slice/rtpengine-daemon.service └─535 /usr/bin/rtpengine -f -E --no-log-timestamps --pidfile /run/rtpengine/rtpengine-daemon.pid --config-file /etc/rtpengine/rtpengine.conf Aug 01 20:58:22 debian systemd[1]: Starting RTP/media Proxy Daemon...

There is another way to check if the rtpengine module is running ? Regards

Connection to AWS services (e.g DynamoDB)
by jakub.smadis＠cloudtalk.io 04 Aug '23

Hello, I am researching how I could communicate from Kamailio (which runs on an AWS EC2 instance) with AWS services (e.g. DynamoDB) using HTTP API. My Kamailio logic is written in Kamailio configuration files. I would like to ask you if anyone has some experience with such a setup and if so how did you manage to connect it? My current options are: * HTTP connection to DynamoDB API with HTTP module I would create a Python script that would generate signature headers for the [AWS API request](https://docs.aws.amazon.com/IAM/latest/UserGuide/create-signed-req…. Then I would use the headers in the HTTP request. (I am using the Kamailio module to keep the connection open to DynamoDB). * Middleman service Small service that provides HTTP API to Kamailio and manages the communication with DynamoDB. Easiest solution but it's harder to maintain it in high availability mode. * API gateway with VPC endpoint attached to the EC2 API gateway would be a proxy to DynamoDB and we would call the VPC endpoint from the Kamailio. We would use resource policies to allow requests without auth through the VPC endpoint. Any help or feedback would be valuable to me. Thank you very much! Regards, Jakub

Hello guys, I have kamailio behind a TLS->TCP Load Balancer. I'm having problems because the outgoing packets have a record has the correct advertise BUT kamailio is assuming that because the outgoing socket is TCP, it adds ";transport=tcp"... is it possible to set that parameter to tls? Thanks! David Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Hello all, I want to save some credentials for different users I have that are being used in a digest authorization (INVITE), with different realms (I don't want the credentials to be hardcoded). I tried to look at how can I read into my kamalio.cfg from yaml/txt file, but haven't found the right module for this. Thanks in advance, Max
