MULTIPLE IP SUBNETS Session Border Controller

[Vsammons]

I have a windows server being used as a "Session Border Controller" and the server has two NIC on two different networks. One is the internal LAN and the other as a DMZ. The DMZ is NATed out to the internert and the LAN is for the internal users to connect to the DMZ.
When I install the "Session Border Controller" software there is no area to select which IP I want to use and the Provisioning is sending the phones the DMZ IP vs the internal LAN IP. I need to set the Session Border Controller to the LAN IP. Is there a way to do this though the CONF files?

I wound up finding a solution to this issue. I put as secondary proxy IP number of the internal LAN on the Yealink T53W under REGISTER ACCOUNT.

You could also use Hyper-V and run a Linux SBC in a VM, and give it whatever IP you wish.

We do not support SBC with multiple NICs. You are also manually editing the phone settings now which is not the supported method of provisioning. It's possible it could stop working after a while with no prior warning.

Use a single NIC on a machine or VM, and put it on the same LAN as the phones.

The LAN must have internet access for:

- The SBC to connect to 3CX
- The phones to contact NTP
- The phones to contact RPS
- The phones to provision via 3CX
- The phones to upgrade via 3CX
