Kamailio isn’t working on my Azure VM, even though it’s set up to use port 5060. The network rules on Azure have both inbound and outbound traffic open for all protocols. I also tried using advertised_address, but that didn’t help either. It looks like no traffic is even hitting Kamailio — none of the routing blocks are triggered.

I’d suggest you increase logging as well as make sure that the system is even seeing the traffic. Something like sngrep will let you see that the NIC is seeing it.
You will then need to confirm nothing is blocking kamailio (ufw,iptables,etc) from seeing the packets. And then, if Kamailio is seeing it, advise of the error and or message.

can you stop IPTables (just in case...) and redo a test call?
And what about SELinux settings? had some issues with it on RH9+ lately....

install sngrep and run it, even if kamailio doesn't receive the packet, if it gets to the vm, you'll see it. If you don't, something before it reaches the vm is blocking it. also set listen to 0.0.0.0:5060 just in case Regards,

The sip message reaches inside the vm, I can see it U 2025/06/04 16:40:24.026418 192.76.120.10:5060 -> 10.0.0.4:5060 #8 INVITE sip:+351200600020@<PUBLIC-IP>:5060 SIP/2.0, the strange thing is that kamailio is working(can send pings to asterisk), it just doesn't want to enter any type of route, I think maybe because advertise doesn't work or any other config is also not working
When you start kamailio it shows the message with aliases and domains associated with it via configuration file. If you see advertise address there - it works.

Can you confirm that Kamailio is listening on the port 5060 udp/tcp ?
something list using NetCat:
nc -v -u -z -w 3 host.ip.address 5060-5070
This will check if anything is listening to the port range from 5060 to 5070 on UDP (default transport for SIP).

The Problem was IPTables all along, when I reboot the rules get cleaned, and I need to add the first two. sudo iptables -L -n -v | grep 5060 4 208 ACCEPT 6 -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:5060 13 13715 ACCEPT 17 -- * * 0.0.0.0/0 0.0.0.0/0 udp dpt:5060 0 0 ACCEPT 6 -- !br-aeab3c66b5ee br-aeab3c66b5ee 0.0.0.0/0 172.19.0.6 tcp dpt:5060 0 0 ACCEPT 17 -- !br-aeab3c66b5ee br-aeab3c66b5ee 0.0.0.0/0 172.19.0.6 udp dpt:5060
Sorry, the problem was iptables, I didn't check kamailio logs when I added the first 2 rules, and after reboot the machine cleans the rules.
Hello,
use some tools like ngrep, sgrep etc.. to see if the traffic is actually reaching the server. Maybe its not Kamailio fault.
Cheers,
Henning

If you run Kamailio via command line with -E option (ex.: kamailio -E -f kamailio.cfg) and set debug level to 3, what is the output? Do you see anything going on when an INVITE comes through?
