Review: Preferred ATA w/1-VoIP; voice quality very good; my setup required a bit of networking knowledge - TL;DR: Preferred equipment with 1-VoIP service; easy to install for most situations but might require some networking knowledge if setup is a bit "non-standard"; voice quality is very good. I've had a landline from AT&T for the last 44 years (25 in the current house). Basic service w/Caller ID runs over $80/month, which is a bit outrageous considering that I'm retired now and we both have cell phones and the majority of the calls to the home line is what I consider spam. As I would still like to have a landline, with my current phone number, and at a more reasonable cost, I (re)discovered VoIP service. I decided to try it out. I selected 1-VoIP as the carrier as they have a good basic plan (Value 500; $9 plus taxes per month, with unlimited incoming calls and 500 minutes outgoing to US and Canada) and talking to their agent confirmed that I could port my current number to VoIP. Their Customer Service and Technical Support is available 24/7 and is US-based. According to the reviews I read about VoIP service providers, they are highly rated. They offer the Grandstream HT802 as the analog telephone adapter (ATA) with the plan at no cost (just a shipping charge), but as I wanted to be able to own the equipment, instead of needing to return it when I don't need the service anymore, I looked around and desertcart had it for sale. It arrived 3 days after placing the order, Feb 12 to 15 (wow! USPS delivered on a Sunday!). The ATA is very easy to connect: plug the power adapter into an outlet, plug it into the ATA, connect an ethernet cable to the adapter and the other end to your router and finally plug in your phone. Because I "brought my own" equipment, I needed to call 1-VoIP and give them the MAC address of the adapter. After a few minutes and a re-boot, everything worked. I made a couple of calls to and from my cell phone to my (temporary) VoIP phone number and the call quality was very good. I noticed no echoing or choppiness to the voice but there was a slight delay between "sending" and "receiving" (i.e., latency). I'm sure that's a given with any VoIP service. As for the quality of the audio, my internet connection has been rated at 500Mbps up and down but I think it's really more like 300+. For my installation I needed to access the configuration pages and change a few things. As shipped, the ATA uses DHCP to get an IP address from the router. Since I wanted to connect the ATA directly to my Xfinity cable modem, instead of my router/WiFi access point, this led to an issue. The Xfinity cable modem is operating under "bridge mode" (I did this in order to keep all of the port forwarding details already in my router). This means that the cable modem does not hand out an IP address. So, poking around the configuration I found where I needed to switch from a dynamic IP to a static IP address, in the range of the Xfinity cable modem (10.x.x.x). There are many, many changes one can make to the configuration of this ATA, it seems very flexible if something needs tweaking. As with any VoIP service, a couple of caveats are noted: 1) Service is unavailable when the power goes out (unless you have a UPS on your internet connection/router). This is nothing new for me as we have been using cordless phones forever and they also are kaput if we lose power. Cell phones are our backup. 2) 911 calling is supported via E(nhanced)911. You must register your physical address with your VoIP provider in order for the 911 operator to automatically get your address. It's up to you to keep your E911 information up-to-date. 3) Stable, quality phone connections are totally dependent on your internet service provider (ISP). If you have a flaky ISP, you'll have flaky VoIP service/quality. As I've only had VoIP service up and running for the last week, I don't have any long-term experience to note here. Maybe in a couple of months/year I'll get back here and update this review.
