Customer Support - no home phone dial tone

Hi,

New Gateway Modem installed - everything works but new home phone line. Verizon was going to disconnect on Oct23, but disconnected early.

Used Xfinity chat and tried all of the below without success.

1. Plugged phone cable from VoIP fully charged phone into Tel 1 on Gateway Modem- no dial tone

2. Plugged a corded phone into Tel 1 on Gateway Modem- no dial tone

3. Rebooted Gateway Modem - no dial tone.

4. Numerous chats with No Success and as a new voice line customer not happy with service paid for and not able to use.

Could the problem be Xfinity needs to verify voice activation provisioning? 

Thank you
