Back Grandstream HT-801 VoIP adapter

Telephone adapters plug into your internet router so that you can use your existing analogue telephone on your internet connection*

This adapter has one socket to attach one older-style analogue phone. It's pre-configured with UK ring and dial tones, our own optimum network settings and your user account details - so you should be able to just plug it into your home or office network and start making calls straight away.

Once installed, all our equipment is auto-provisioned; this means that we can remotely adjust its settings to keep it up to date or perform remote diagnosis and maintenance if required. This ensures that your hardware is running at its best all the time.

*Adapters generally only work with one phone. If you have internal wiring for extensions there are often ways of making all the older phones on it work with an adapter, but it will require some changes at the master socket. Depending how old your master socket is we may be able to advise on this, but generally a better solution is to replace existing phones with a wireless solution such as our Gigaset DECT phones.
