disallow=all
alwaysauthreject = yes
deny=0.0.0.0/0.0.0.0
permit=88.99.xxx.xxx/255.255.255.0
externip=88.99.xxx.xxx [Asterik server IP running on cloud]
localnet=192.168.1.5/255.255.255.0 [My Computer Local Ip address]


[Pokhraj]
;type=friend
type=peer

allow=ulaw,alaw
secret=xxxx
host=dynamic

Your NAT setting is incorrect, so it’s not being applied. You want:

nat=force_rport,comedia

Hello jcolp,
Awesome. Its working as expected. But one more confusion. :frowning_face:
As per the above configuration, I am able to call and the receiving party is able to hear my voice.
Now when the receiving party is saying something, I am not able to hear anything. Please note his system (Laptop) is also behind NAT, as he is also using router at his point for internet.

Is there is any more configuration I need to perform from my side or his side?

Please advice.

No, but you need to isolate the problem further. For example “rtp set debug on” will show you media flowing through Asterisk. You should also check port forwarding to ensure that the RTP range is forwarded to Asterisk if it is behind a router or something.

Are you talking about the remote receiver RTP range? Is my understanding correct?
Also could you please put some light about the default RTP range for Asterisk.

Thanks

No, I was referring to if Asterisk is behind a router. You did not specify the network layout - so I can only guess.

The default port range for Asterisk RTP is 10000 - 20000 and is configured in rtp.conf

Maybe it is a stupid question. Why do you need NAT routing on the Hetzner box? Wouldn’t a normal firewall do the same thing in your case?

If so, why don’t you run something like pfSense and let Asterisk also run under this system?

If you have several SIP devices within your LAN, I think it makes sense to consider running a SIP proxy on the home router, but that depends on which router you are using (Lancom has an additional module, but with a Fritzbox you are out of luck, I think).

Hello,
The below is my current configuration…

  1. I have a private IP which provided by my ISP. [192.168.10.24]
  2. I am using router for internet.
  3. My asterisk is running on cloud server which have a ip as [88.29.xx.xxxx].
  4. I have port forward at my router the default port for asterisk [5060] for outgoing.

So, Do I need GLOBAL_IP for connecting x-lite from my desktop ?
Also Do I need port forward [10000-20000] for incoming call?

Please explain this as ISPs generally provide only public IPs and it is the local router that doe any NATting to private ones.

(I’m also curious as to why so many people insist on putting low processing high traffic volume servers on remote (cloud) sites, but that is more an audio quality issue, although in this case it is adding complications, by by exacerbating the NAT complexity. I’d seriously consider running NAT from your private network to the cloud server, for security as well as to simplify the IP address hackery.)

Sadly with the exhaustion of IPv4 address space this is no longer true in many markets.

‘Carrier Grade’ NAT is popping up everywhere.
