Install Orbi RBR40 with TWC Sagecom Fast 5260 router and Arris TM1602 modem

Question

I have TWC/Spectrum telephone landline and internet using TWC’s Sagecom router and Arris modem. &nbsp;I connected my new Orbi RBR 40 (router and 2 satellites) to the single Arris ethernet port, but had to disconnect the Sagecom router from the Arris modem in order to do so. &nbsp;I now have internet, but no TWC telephone service. &nbsp;How can I recover my telephone service and keep Orbi’s working? &nbsp;Am I configured correctly?
