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

0 votes

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.

I subscribed for PUSH Proxy and then enabled it on ZoiPer running on my iOS Phone and I get the register error: Push Server is Unable to Connect to Home Registrar Server...

In this case I have full control over the Home Registrar Server and I don't see any SIP register requests coming on to the Registrar Server.

I tried many other configuration changes like use TCP for transport etc., but nothing seems to help. As soon as disable PUSH Proxy then everything works....

My questions are:

1. Does the SIP Provider needs to do any changes to make ZoiPer Push Proxy work with it? If yes, what are these updates?

2. Does the ZoiPer Push proxy "server" registers the SIP Account at the SIP Provider registrar server instead of the ZoiPer soft-phone on the mobile registering directly?

Any help to gets this Push Poxy working is highly appreciated.
