NR5101 - Problem with VoLTE calls
Hello everyone, I have a router connected to a 5g SIM with a data plan and unlimited calls.
I bought a voip phone that I connected via rj11 to rj45 cable.
Unfortunately, when I receive a call, the phone does not ring but the router shows that the missed call.
I can't make phone calls either.
The router setting has already been set to VoLTE service.
Do you know how to help me?
Looking at the ports diagram in the user guide for NR5101 available at https://support.zyxel.eu/hc/en-us/articles/4403365084818-5G-Devices-Advanced-Downloads-Firmwares-and-other-resources- , the Phone port is an RJ11 socket.
So I think that you don't need an RJ11 to RJ45 adapter.
You need to plug an analog phone into the Phone port to make a VoLTE call according to section 4.12.6 of the user guide.
I hope that this is helpful.
My NR5101 router has no phone port but only two ethernet ports. For this I connected the phone with the adapter to RJ45.
How can I do?
Do you have the Nebula version of NR5101 with a QR code on the base?
- because that version does not have a grey coloured phone port.
- see the following Zyxel support video for the differences: https://youtu.be/yMQClWOAjqU
In which case, you can only do VoIP and not VoLTE.
Yes, I checked now and I have the nebula version. So there is no way to use the calls that I have included in the sim card?Not even with a computer software?In case you want to use voip calls where do you plug in the phone?1

I don't think that you can use VoLTE with the Nebula NR5101.
It is not mentioned in the Nebula NR5101 user guide available at https://www.zyxel.com/global/en/support/download linked from https://www.zyxel.com/global/en/products/mobile-broadband/nebula-5g-nr-indoor-router-nebula-nr5101
Your options then are to do VoIP with a VoIP digital phone, e.g. those made by Yealink or Cisco, or use an analogue phone with a SIP Analogue Telephone Adapter (ATA) such as a Grandstream HT812 (which I use with my Zyxel router gateway and Sipgate)
The VoIP phones or SIP ATA would need to be plugged into a RJ45 network LAN port.
I hope that this is helpful.
Kind regards Tony0
