Did you already configure the NAT settings under the SIP Settings?

Where do you have installed your PBX?

Did you already check that the ports 10000 to 20000 be allowed in any additional router or firewall?

The nat is use when you connect with other ip that isn’t the IP address the remote sip server, are you doing that? I think that the problem is firewall.. can you to use tcpdump??

The first thing is to verify if your extension and vitalpbx are exchanging audio correctly. could you dial * 98 to see if you have audio ..? the extension that you are using is a softphone or physical phone, remember that many times in the user’s device you must enable the nat also ..

Does your vps have anextra firewall?

Does your vps have two IP Address? For example, Amazon vps has one private IP and a public one.

You may check first local audio, dialing a feature call or calls between extensions.

I have this questions:

What vps provider are u using?

Does your vps have an extra firewall?

Does your vps have two IP Address? For example, Amazon vps has one private IP and a public one.
