Cox has a limited list of certified cable modems available to purchase. They recommend an SB8200, although in the feature list, it states that digital voice is not supported.

I have a grand stream IP PBX system and wanted to see if this system will actually work with the 8200.

Do I simply setup my internal router connected to the 8200 and setup a NAT from my fixed public IP address to the IP PBX system through my router? Or does this configuration not work with the 8200?

Still trying to decide whether to purchase the 8200 for my configuration.

 

Thanks

SB8200 is just a cable modem so you can connect router to the modem to setup PBX system through the router for proper connection and internet service.
