voip phone not working;

Using tp-link archer 1600v.

Received this modem aas a replacement and the voip phone has never worked.

I have tried two phones and two phone lines connacted to the phone 1 outlet.

No phone1 led on the modem.

Phone has dial tone but high pitched squeal after dialing out.

"Call cannot be connected at this time" voice message when dialing in.

Please advise
