Xfinity Voice Activation fail (but data works)

My new SBV3202 was recently activated and data works.

Voice on new modem has never worked (the Voice Line LEDs on modem do not turn on) and no dial tone from either Tel port.

I have done Modem Resets, and used the Xfinity ‘Activate Voice’ page.

My telephone works fine - same one used with previous (netgear) voice modem.

Talking with Xfinity is such a pain… thot maybe there was a modem setting I should try first?

Thanks.
