I am wondering if there is still a plan to update the firmware for the CM2050V modem problem or is this something that is no longer in the works? I purchased this modem months ago specifically for the voice feature and have yet to connect my phone because I am waiting to see if this is going to be fixed or if I should move on to a different modem. Thanks.

Believe what OP is referring to is the Comcast/XFINITY issue regarding compatibility with ISP's "enhanced speed" plans (mid-split setup). You may recall that the CM2050V was on ISP list as a compatible, and recommended, cable/voice modem option suitable for higher upstream speeds in areas "upgraded" by Comcast/XFINITY. However the firmware update pushed out which allowed access to higher upstream speeds (V09.01.01) created significant stability issues for many other owners. The FW for Comcast/XFINITY was then rolled back to older version V02.01.03 which removed the "access" to the higher upstream speeds. In my limited contacts with each company, both Netgear and Comcast have pointed fingers at each other and though an earlier response to someone else on the topic made it sound like a FW update was being worked on by Netgear "with highest priority", the topic has gone completely silent on both Netgear and Comcast ends, leaving many owners $300 out of pocket for a modem that likely provides no discernible benefit over previous cable/voice modem. So...voice works and the cable modem works, but only to access standard speeds and not to access the "enhanced speeds". Neither Netgear nor Comcast are providing any updates and most threads seem to be closed down, and Comcast continues to push customers to "rent an Xfinity gateway" which most purchasers do not wish to do in the first place.

It's up to the ISP and chipset Mfr at this point.

Would be something to contact the ISP about. Voice has been supported on this model modem since it first came out. If there is a problem, the ISP would be to send out a tech and have them help you with getting that working.

Thank you for your response. I have not attempted to connect a phone yet to this modem as I am waiting for them to fix the other problems with it so I don't know if voice works or not. If Netgear doesn't plan on putting out new firmware then I am going to need to get a new modem and there isn't really anything else to choose from that is acceptable to my ISP and I don't plan on renting equipment from them so I will need to find another phone service. Right now my phone is with another service that I may not have for much longer and I don't want to port it to my ISP until things are corrected

    Who is the ISP your with?
    
    The CM series should work for your phone needs. It may not be a FW issue in your case. The ISP needs to check all the lines and signal up to the modem and also check the phone line connections from the modem to your phone devices. There could be cabling or phone line (RJ11) box interconnect issues that a phone line tech should take a look at.
    
    Can post the following captures for review to see if there are any signal line issues up to the modem if you want:

The CM2050V voice feature works fine on Comcast. Who is your ISP?
