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).
==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 needs to use an IPv6 syslog server, but it just works.
==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 whitelist and blacklist for web, telnet, and ssh access to the ATA. Unfortunately it only accepts IPv4 address ranges (I have a support ticket open with Grandstream about this). ''Basic Settings'', ''Web/SSH Access'', ''White List for WAN Side'', similar for blacklist.
