tp-link AX5400 Model VX420 Voip Phone Not Working

[jeffw]

I received a new TP-LINK AX5400- VX420 modem to replace the existing Huawei modem which died last week.  The NBN service is FTTN. The new modem is powered on and connects to the internet OK but the VOIP phone is not working.  The phone LED does not light at all and if I try to make an inbound call I get a recorded message saying the number is not connected.

I have done the normal troubleshooting

1. Rebooted modem

2. Replaced cable between modem phone port and telephone handset

3. Tried another telephone handset

Any ideas?

Cheers

Hi @jeffw

Welcome to the Community!

Since this is a new replacement modem/router, it is possible that we still need to update the system that the replacement device has been installed.

We'll raise this with our Tech team and have someone to contact you today between 1PM - 2PM using the number on file to discuss the process.
