This is not true as I don't use the hyperhub and have my telephone service up and running. My Netgear router is connected directly to the Hyperoptic socket via ethernet. I have a gigaset Go 100 box plugged into an ethernet socket on the netgear hub (Actually its via a switch). I then asked Hyperoptic for the SIP settings and entered these in the Gigaset Go 100 box and everything works fine - has done for several years.

In reply to a post by Hyperoptic_CS:

Hi there,

We'd like to assist you with this.

It�s important to note that our phone service will only work through our Hyberhub router. This means that, if you choose to use a third party router instead of our Hyperhub router, you will lose the ability to use your phone.

In order to use our phone service with a third-party router, the Hyperoptic hub and your router will need to be connected in a bridge mode, but in a way that Hyperhub is directly connected to the wall socket.

In order to set up the bridge mode, please follow the steps below:
-Connect your third-party router�s LAN port to the LAN port of our Hyperhub router
-Disable DHCP service on your third-party router
-Disable the Wireless signal on our Hyperhub router (or call us and we can disable it for you, if you only want the third party router broadcasting a wireless signal).

If there's anything else we can assist you with, please let us know.

Thank you.

In case anyone is interested, I've just replaced my Hyperoptic router with an Asus RT-AC86U.

I bought a Gigaset Sculpture CL750a GO phone, and configured it with the SIP username, password and server given to me by Hyperoptic, and all working as expected.
