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'.
* 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).
You can set up distinctive ring tones based on the calling number, and it even allows matching on part of a number. I use '020836xxxxx' to match calls from a number of exchanges on the northern edge of London (which is where your author lives). You can't match a E.164 number (+442036xxxxx) directly but under ''FXS Port'' is an option ''Replace Beginning '+' with 00 in Caller ID'' which changes +4420... into 004420... which can be matched.
==IPv6 Only==
I finally bit the bullet and configured the unit for IPv6 only. It needs to know about IPv6 DNS and NTP servers, and would need to use an IPv6 syslog server if that service is required, but it just works. Note that the options for getting its IPv6 address are DHCPv6 or static config - it doesn't seem able to use SLAAC.
==Firewall & Security==
*You will also want to set up firewall rules, as per the [[VoIP Firewall]] page.
*Also see the [[VoIP Security]] page for information about securing your VoIP service.
*You can have an IP address
