Incomming Call Rejected

[wlt7913c]

I just downloaded and installed the Free version of the PBX and I am testing it using the 3CX softphones. I have one internal to my network and one external to the network; 100 is within the network, and 101 is outside the network (external). I can call 101 from 100 it rings connects etc. no problem. However I cannot do the reverse. When I try to call from 101 to 100 the call fails. on the 3CX Debug screen it simply says "Forbidden" on the server...

Can someone tell me why this happened and perhaps how to fix it?

What I would suspect is that you don't have STUN enabled on the remote extension. When it registers 3CX should see the port number to be something like 5060, not 65385

According to the advanced settings in the softphone STUN is enabled and using the 3x site.

I'm seeing IP addresses that don't seem right. 97.67.154.83 looks like the remote extensions public IP, which is fine. You should not be seeing other IP's that begin with 209.168 and some with 192.168. I'm going to assume that the IP's with 192.168.XX.XX are on your local LAN. Where are the 209.168.XX.XX coming from? Is that the internal LAN range from the remote site?

When Ext 101 registers it does so with the public IP and a port (65385) but the Source shows a private IP and port 5060.
