I got 2 site and 2 pbx's on one side a s100 and the other side a s20 I cant get them to connected to each other. I have an extension set up on each one for remote register. I have the nat setup with the pubilic IP. I forwarded 5060 and 5061 to the PBX's  I have rules set up in the firewall to accept traffic from the remote sites.

The only thing I can think of is the setup for the internet is a bit ODD the public IP address is delivered to a mikrotik radio which has its own internal  ip range, there is a 1:1 nat on the MIkrotik to a Cisco router on site this cisco router is where I done my port forward to the PBX

  1. Try using a mobile phone with 3G/4G internet connection and register a softphone to the 2 PBX and make sure you can register correctly; 

  If this the softphone couldn't register correctly, it is suggested to check the port forwarding on both PBX first;

  2. Try login via SSH and see if you can get ping response from another side of PBX;
