Ooma Service Blocked?

Question

I have the Verizon 4G LTE Router and cannot get my Ooma to make outgoing calls (incoming calls work fine).
The Ooma diagnostics report ports 123 and 53 are blocked.
I've tried the following, to no avail:
Forwarding ports 53 and 123 to the Ooma device (after reserving its IP address to make sure it doesn't change)
Putting the Ooma device in the DMZ
This leads me to believe Verizon Wirelss is blocking my VoIP service. Their technicians, on 2 separate calls, denied this and said all ports are open.
Am I missing anything? Is it possible to get Ooma running the the VZW 4G LTE network?
Thanks!

Verizon is blocking your communication on those ports as they are not some of the few normal and well known ports used by most users.  VZW is blocking access from the network firewall level which means there is nothing you can do from your device to allow the communication.  VZW will not make an acception when it comes to thier firewall.
Here are your options:
1. Purchase a Static IP Address for $500.00.  Static IPs are outside of VZW's NAT Firewall where custom port configurations are allowed.
2. Setup a VPN to a server on a network that normally allows this communication.  VPN's can be established on a PC or at the router level if you care to purchase or configure your router to do so.
3.  Cancel your VZW service and sign up with someone else who does allow those ports.  No recomendations for you on this particular subject.  All wireless ISPs are likely to behave the same way so you would likely have to go DSL or Cable.
