I was assuming an outgoing registration. If this is an incoming one, then it isn’t reaching the router and you need to debug upstream of the router.

I’m getting this
Am I missing anything in sip.conf file?
This seems not UDP trafic but TCP on port 443. Try the same by adding and udp to the tcpdump command

I think I got the real problem as you can see in log 5060/udp closed. But not getting any proper solution to open it.
Here is my port status
sudo ufw status
Status: active
To Action From
-- ------ ----
5060/udp ALLOW Anywhere
10000:20000/udp ALLOW Anywhere
5060 (v6) ALLOW Anywhere (v6)

10000:20000/udp (v6) ALLOW Anywhere (v6)
5060/tcp (v6) ALLOW Anywhere (v6)
Can anyone guide me whats going wrong.
Thank you.
Can’t understand how the UDP/5060 port is closed on your asterisk server and in the mean time your phone from local network are connected as you showed earlier with IP 192.168.0.101!
run tcpdump -ni any src or dst 87.193.70.149 and udp

Now I opened that by doing some network troubleshooting. Still not working from outside network.
is my local_net=192.168.0.94/24 is in correct formation?

Solve your network problem: you need to see UDP traffic to & from your outside provider on your asterisk box.
I changed the port to 7060 and its got connected now but after this in Zoiper I’m getting PUSH flags and in Asterisk console I’m getting these error.

Thank you
Okay this also solved restarted the Asterisk server then started working.
I learned these
When you are configuring pjsip then only you need to edit the following file pjsip.conf and extensions.conf and if 5060 port showing any kind of issues then point to other port and port must be UDP port. Also forward port in your router and try to have subneting and musking knowledge.
My Infra config is Ubuntu 22.04 and Asterisk 20.5.2
Thank you everyone.

You went through a lot there to get your system working so it’s also good that you posted your fix.
Yes it took almost 3 days but good very good Idea about initial setups. But now facing other issues like not able to hear voice from outside network but in local everything is working fine.
Voice issue I will solve tomorrow.
Did you open your ports 10000-25000 via the rtp.conf file? since you’re behind NAT I would suggest also setting up STUN Make sure your router has ports forwarded to your server as well
Yes I have forwarded these ports in firewall and also forwarded in router.
Now I solved it as it was a client side problem not server side as client was dialing via only SIP but should be SIP+RTP depending upon your client application or Hardphone.
Thank you
