[Serusers] Newer VOIP devices ?

[Bill]

    Is anyone familar with the newer VOIP devices that sit outside the LAN
between the cable/DSL modem and the firewall/NAT router? I understand AT&T
is using something like this but what they use has a device like a Cisco 186
and a router built into one for under $100. Basically, it's a SIP friendly
router with POTS ports. Vonage has something like this mentioned on their
web site as well. This allows them to offer SIP/VOIP services quickly
without having to battle the NAT problems.

    Anyone using such an animal?
