Similar units are the HT802 (which has 2 FXS ports), and the HT81x series (which adds a NAT router, and is available with different
numbers of FXS ports).
If supplied without a Quick Start Guide, connect to a router which acts as a DHCP server and connect a telephone to the unit. Then dial '***' to access the internal Interactive Voice Response (IVR) system. '02' will read out the unit's IP address(es). Point a web browser at one of those addresses, and login as 'admin','admin'.
*''Basic Settings'', ''Internet Protocol'', select ''Both, prefer IPv6'' (or, if you're brave, select ''IPv6 Only'')
*See https://www.ukvoipforums.com/viewtopic.php?t=1061 for UK settings (although you might want to set the ''NTP Server'' to ''time.aa.net.uk'' as that has IPv6 addresses)
*Can support pulse dialling handsets - ''FXS Port'', ''Enable Pulse Dialing'', select ''Yes''. As a bonus, this allows a pulse dialling handset to interact with IVR systems - at least until the system asks you to press '*' or '#'.
*Can send BT CLID to handsets, see UK settings link above
A couple of personal favourite config options:
* There's a confusingly explained option under ''FXS Port'' labelled ''Use # as Dial Key'', explained as ''if set to Yes, "#" will function as the "(Re-)Dial" key''. If set to ''No'' the # key works as a normal key, if set to ''Yes'' it acts as a special key variously named ''Send'' or ''Dial'' which can be used as ''Redial last number called'' - but that'll be the last number dialled by the unit, not the last number dialled by the phone concerned. I set it to ''No'' to avoid surprises.
* Also under ''FXS Port'' are some options regarding Hook Flash. This corresponds to what the UK calls ''Timed Break Recall''. I set the option ''Enable Hook Flash'' to ''No'' - otherwise you can think you've hung up on a call by tapping the hook switch but you haven't (and your phones ring to remind you - so you pick the handset up and find the other party is confused too).
