They have some shady business practices, if not outright illegal. Thank God my credit card company could see just how incompetent and deceptive they were and reversed the charges. Avoid ADR.

I see good results in the Seattle/Metro area. That’s a fair point, the quality of carrier networks do vary by region. I see good results in the Seattle/Metro area.

Although Comcast owns its network unlike Vonage, the technology of a loop based cable modem service simply doesn't guarantee you enough bandwidth. We have plenty of dental offices that signed up for the comcast / optimum phone service only to cancel a month or two later. In mostly residential area's in Norhter NJ, cable modem service for phone just isn't strong enough. Jonathan Jonathan

Most commonly we use the Netgear Prosafe FVS338 with the 3.0.4 firmware (the newest release adds a SIP ALG so we don’t use it). To work with the ALP 160 this unit requires a static LAN IP and can be setup for manual port forwarding or IPSec. For remote sites the Netgear WNR3500 with firmware version 1.0.22_6.0.22NA is your best bet for an Aastra tested uPNP router which is still in production.

We are still unable to get the remote phone working properly. My Arris modem (model TM602G/CT) from Comcast has no configurable settings; it's a black box. I can access the admin page at http://192.168.100.1/ but there is no way to change anything, no admin login of any kind (and no indication of a firewall in use). Can you tell me which router make and models you have had success with? We have DLink GL4300s, which do not have "traditional" port forwarding settings (where you map a WAN port to a LAN port) but rather allow traffic from specific IPs to specific ports/port rangers.

Log onto the gateway (default 10.1.10.1) go to firewall, then make sure "Disable Firewall for True Static IP Subnet Only" and "Disable Gateway Smart Packet Detection" are checked. Then make sure your routers are set to the static WAN IPs (you must have static IPs from your ISP). I use shieldsup to then test the ports manually: https://www.grc.com/x/ne.dll?bh0bkyd2 One problem with the Aastra is most of the certified firewalls are no longer in production! You really either need to manually port forward (which we've done many times successfully), create an IPSEC VPN between sites, or locate a compatible router (list on the release notes).
