CM1150V Voice Not Working

CM1150V Voice Not Working

I purchased the CM1150V from netgear to replace the Altice modem from Optimum so I could fully access my smart home systems.  The modem was provisioned by Optimum when I called and internet works just as it should. However I cannot get my phone service to work.  It was working on the Altice modem immediately before.  Optimum says it is set up on thier side.  Is there anything I need to do to get it working or could there be something wrong with my modem?  Any help appreciated.

Either ISP or a tech needs to check the phone lines in your home. You'll need to contac the ISP for help in this. If this worked on a different ISP and isn't working on the different ISP, then the newer ISP needs to look into this.

It is the same ISP (Optimum).  The only difference here is the modem.

   I know nothing, but does "optimum" offer "XFINITY(R) Voice"?  I would
think not.

 

   Perhaps a forum search for "CM1150V" would find some useful
information.  Mine found, for example:

Re: CM1150V Voice Not Working

Hi. Working with Optimum is a brutal process. Speak to 5 different people and you’ll get 5 different answers on almost any topic. Modem says it’s for Xfinity but also compatible with other service providers and optimum actually told me to buy this modem. In the end, I also had an older modem (slower speed) that I used for my phone while my internet runs through this modem.

Hey Greg, were you ever able to fix the situation? I'm having the same issue with optimum voice

Unfortunately I did not get it working.  Solution for me was two modems - one for internet and one for voice.
