Set up the service provider and calling rule in ZX100-B to make it register to ZX100-A.
This method is almost the same as above, EXCEPT you need to use the 210.11.25.127
as the service provider instead of 192.168.1.21.
Step 3: Set port forwarding in the router for ZX100-B
Use the same method as Step 1 do port forwarding in router-B for ZX100-B as above.

Accordingly, set the 601 users in ZX100-A and 801 users in ZX100-B, and build the
correct dial rules as above, you can make calls between two the ZX100 IP PBX.
Noted:
You can also apply a DDNS to get one fixed domain for both ZX100 IP PBX and
connect to each other rather than use the Port Forwarding in the router.
