This hard
phone is another ATA (analog telephone adaptor). It enables
you to connect your POTS (plain old telephone system) phones
to the Internet. Think of it as a phone jack for VoIP. It
has one ethernet port and two RJ11 phone jacks. This is one
of the most feature rich and easy to use ATA that we have
tested. Out of the box, it is configured for DHCP. This means
that it gets its IP address from your DHCP server automatically.
Full documentation can be found at Sipura's site.
NOTE: We have seen instances
where installing the SPA-2000 behind a firewall which blocks
ICMP packets causes problems with registration. Try turning
off any ICMP blocking on your firewall.
