no dial tone

On Tuesday  I went to the local Xfinity store to remove the cable TV part of my Xfinity package, leaving just internet and voice/phone.   As part of this I received and installed a new modem/router.   The internet is working fine but there is no dial tone on the phones.   Following the troubleshooting instructions, I plugged one of the phones directly into phone port 1.  Still nothing.
