Hello,

I'd recommend contacting support@voipo.com for further troubleshooting if you're still having problems.

It appears that STUN has been enabled for the device. If you're still having problems, we can further tweak some setting to hopefully get it working properly.

Submitting an email that opens a trouble ticket is the best way for us to work on this issue so that we can exchange information that would normally be private (not suitable for a forum post).
