What is the Mfr and model# of the ISP modem the NG router is connected too?

Try putting the SPA112 devices IP address it gets from the Orbi router into the routers DMZ. Setup a IP address for this devices ON the router as well. Apply and save changes. Do a full reboot of the Orbi router and the SPA device.

The issue is that when the inernet drops for whaetever reason the VoIP service cannot reconnect once the internet is back online and the only way to reconnect it is to cycle the Orbi on and off.

Cycling on and off the HFC modem or SPA112 on their own does not reconnect the VoIP service.

I have disabled SIP ALG on the Orbi and I have set NAT "Keep Alive" on the SPA112.

The cable modem is an Arris CM8200.

  Let us know if the DMZ helps on the Orbi any for the SPA device.
  You should be good at the modem. This is a modem only with no built in router.
