Push Server is Unable To Connect To Home Registrar [...] 408

Connecting to FreePBX 14 behind NAT. 

pt 5060, 10000:65535 UDP passed through and logged on firewall from and android device address

I'm seeing TCP connection attempts at the firewall from the zoiper ip range on varying high ports - what do I need to allow through the firewall and what do I need to configure on FreePBX/Asterisk for registration with the push server enabled to work correctly?

If you see incoming connections over TCP, this means that your SIP account is probably set to use TCP as transport. As I understand from your post, you have opened the UDP ports only.

In this case try changing the SIP account transport to UDP or open the TCP ports on the firewall.
