CUBE behind firewall

[abhishek.c.kum]

Hi,

My Infosec team suggested to place Firewall between ITSP and CUBE. My ITSP provided /29 IP pool to connect with their SBC to register the SIP trunk. 

Any high level or Low level reference document and best practices to implement it will be very helpful.

Hi,

It's always a good chioce to place Cube behind a firewall.

In the following doc , you can find an example of a Cube talking to MS Teams for Direct Routing solution.

As you will see, the cube is behind a Fwall and also could be natted.
