Ok here I have a theory. XPro under the covers uses a STUN server to handle NAT traversal.

I suspect the acknowledment messages from your ATA are not getting back to Betamax (hence the continuing ringing and one way Audio).

Are you able to configure a STUN server in your ATA?

If it does support STUN, try using stun.voxalot.com.au:3478

Also make sure your firewall is not blocking the outbound messages.
