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.
