Step 2: Set up the Provider Host in IPX-1980-B
Set up the service provider and calling rule in IPX-1980-B to make it register to IPX-1980-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 IPX-1980-B
Use the same method as Step 1 to do port forwarding in router-B for IPX-1980-B as above.
Setp4: Combine two IPX-1980 and make calls
Accordingly, set the 601 users in IPX-1980-A and 801 users in IPX-1980-B, and build the
correct dial rules as above, you can make calls between two the IPX-1980 IP PBX.
1. You can also apply a DDNS to get one fixed domain for both IPX-1980 IP
PBX and connect to each other rather than using the Port Forwarding in the
router.
