ContributionsMost RecentMost LikesSolutionsTimeline (2nd Post) for Docsis 3.1 eMTA modem? (Repeated Question - Coxapparently doesn't want to say it's a marketing scheme dreamed up by the execs.) I currently receive phone service through an eMTA modem. I have recently decided to upgrade my modem to a docsis 3.1 modem. However, there are not any docsis 3.1 eMTA modems on the Cox approved modems list for lower tiers. Is there a timeline to the availability of a docsis 3.1 eMTA modem, specifically the ARRIS Touchstone TM3402 eMTA, to the Cox approved modems list FOR LOWER PRICE TIERS THAN GIGABLAST? Re: Timeline for Docsis 3.1 eMTA approved modem? A secondary question: If Cox forces you to rent eMTA approved modems to use the Cox VOIP service, are there alternatives to renting from Cox for phone service? Specifically, using a new Cox approved docsis 3.1 modem, and a VOIP adapter, such as the Cisco SPA122 ATA? Or is this a marketing and billing scheme to force renting the device from Cox?
