Review: great VoIp phone, good solid feel, high quality - The wife lost her mobile phone, and we had no house phone, then I researched options and stumbled on this VoIp solution and I love it. (great audio and Voip service is a fraction of the regular cost) I had this phone for a while now, and it's been on standby in the living room for months, staying connected to the wifi service, very reliable. The feels is great in the hand, seems solid and the audio is good, better than what I expected. (my other VoiP phone was a Skype phone decades ago and I remember it had poor audio and felt very low quality and plasticky, but not this one) Set up wasn't that bad, the meanu features are what you expect, contact list, etc.. I like it a lot, was going to give it 4 stars because it is a bit smaller than what I expected, but that's a preference I guess.
Review: Great phone. You have to have a VOIP service for the phone to work - Great phone. Well built. Sound quality is excellent. Everyone should know you have to have a phone provider. I use voip.ms The basic plan is $0.85/month and $0.009 per minute. So less than a penny a minute. Or $4.95 per month for 3500 minutes. What I like is I can use the phone on any WiFi network and the phone remembers the network. Setting up the voip.ms account can be a little intimidating but chatgpt can be of great assistance. Let me see if I can explain the basics. Create your voip.ms account. Note residential you can purchase up to 5 numbers. After your account is created and funded. Purchase a DID. This is going to be your phone number. It's organized by State and City. Next create a sub account. This screen has a lot of options. The only thing you are going to fill out is the user name and a password. user name starts with 6 numbers and _ So something like 123456_House Phone. Next create a password. Write down the user name (example 123456_House Phone) and password. You are going to use this to enter into the phone. In the CallerID Number box Use one of my DID's should be selected and your number should be in the field. Leave everything else on the screen as is and click create account on the bottom. Next from the above menu click on DID numbers and manage DID's. Click on the DID then click the orange box with a pencil. (edit DID). Another intimating screen. Don't worry you are only going to change a couple things. First field SIP/IAX select the sub account you created. example (123456_House Phone). Leave everything else as is. Next all the servers select one nearest you. Whichever one you select I suggest taking a picture of it. You are going to enter this into the phone. Once the server is selected go to the bottom of the screen and click the "click here to apply changes" button. Congrats you now have a working phone number. Next we are going to set up the phone. You need to boot the phone and connect to your wifi network. Once connected to wifi scroll through the menu on the phone and find the phones IP address. Using a laptop or desktop type the IP address of the phone in a browser window. User is admin. You will get a code on the screen of the computer. Enter this code on the phone. Then you will be promoted to change the password. Now that you are logged into the phone on you computer we are going to set up account 1. Click the edit there are multiple menu's. Don't worry we are only going to be interested in a few. General settings. Account name-Anything entered here will show up on the display of the phone. Maybe something like House Phone or you can leave it blank. Next field SIP Server. Enter the server you selected and took a picture of. Example atlanta1.voip.ms This has to match exactly what you selected in voip.ms. Next skip 3 fields and goto SIP User ID. The is the sub account from voip.ms example 123456_House Phone Enter your info exactly as it is in voip.ms The next field is SIP Authentication ID. Enter you info again example 123456_House Phone Next field is SIP Authentication Password This is the password you used when you created the sub account in voip.ms Enter you password here. Then at the bottom of the screen click save and apply. At this point your phone should work. Some other resources if you run into issues. Chatgpt. Also you can email support and ask for the video from the recent workshop. It goes over all the features of voip.ms Good luck and I hope I helped someone with their phone!

### ⭐⭐⭐⭐ Grandstream WP826: The Cordless SIP Phone That Loves Good Wi-Fi and Judges Bad Wi-Fi
*by D***Q on November 26, 2025*

The Grandstream WP826 is one of those cordless Wi-Fi SIP phones that immediately impresses you with how capable it is… right up until the moment you walk ten feet too far and it suddenly remembers it’s not a DECT handset. In normal use, though, it’s a genuinely solid device: lightweight, comfortable, well-built, and packed with features that make it feel far more premium than its price suggests. The interface is clean, the audio quality is crisp (especially on decent SIP backends), and the battery life lands firmly in the “reliable workday companion” category. For offices, warehouses, and anyone tired of being tethered to a desk phone, it’s a surprisingly easy product to like. Where the WP826 shines is everything but the Wi-Fi sensitivity. Once it’s in good RF, the handset behaves flawlessly—calls stay stable, roaming is smooth enough, and the hardware seems perfectly tuned for daily work. It feels like the kind of device you can hand to a staff member and trust that they won’t immediately break it. The buttons are responsive, the speakerphone is better than expected, and the whole device has that “we designed this for real people, not lab benches” vibe. Grandstream’s SIP stack is strong, provisioning is painless, and the phone integrates cleanly with most modern PBXs without a fuss. But yes… the radio. It’s not bad, but it’s undeniably pickier than it should be. In environments with strong, consistent Wi-Fi coverage, the WP826 behaves beautifully. In areas with marginal signal, noisy 2.4 GHz, or imperfect AP placement, it can get a little diva-like—hesitant to roam, slightly clingy to weak signals, and occasionally stubborn about re-establishing full strength. It never becomes unusable, but you absolutely notice the sensitivity curve. If your Wi-Fi is dialed in, it’s invisible. If your Wi-Fi is “good enough,” the handset will remind you that no, actually, it isn’t. Despite that quirk, it’s still a genuinely recommendable device. The build quality, SIP reliability, and day-to-day usability easily outweigh the Wi-Fi finickiness. For businesses with solid Wi-Fi design—or anyone willing to tune their coverage even a little—the WP826 lands as a dependable, flexible cordless handset that feels like a modern alternative to aging DECT systems. The one caveat is simply knowing your RF environment; treat it right, and it’ll reward you with stable calls and excellent ergonomics. ⸻ Pros • Comfortable, lightweight, and durable build • Strong SIP implementation with easy provisioning • Good audio quality and solid speakerphone • Great battery life for all-day use • Excellent day-to-day usability in well-designed Wi-Fi environments Cons • Wi-Fi sensitivity is noticeably pickier than it should be • Roaming can hesitate in marginal RF • Requires decent AP density and tuning for best results • Not suitable for environments with weak or inconsistent coverage
