The WP810 is a portable Wi-Fi IP phone designed to suit a variety of enterprises and vertical market applications, including retail, logistics, medical and security. This basic cordless Wi-Fi phone comes equipped with integrated dual-band 802.11a/b/g/n/ac Wi-Fi, an advanced antenna design and roaming support. By adding 6-hour talk time and HD voice with dual-MICs, the WP810 offers an affordable option and comes equipped with a combination of features, mobility and durability to suit all portable telephony needs.
Don’t do it to yourself, get a DECT phone if you can.My office started working from home at the beginning of the pandemic, and eventually our lease ran out and didn’t get renewed. For the longest time our Asterisk system was forwarding calls to peoples’ cell phones when their extensions were dialed, which was a good interim solution (back in March 2020, we were supposed to be out of the office for “2 weeks” and then it was all supposed to blow over).Annywho, eventually came the edict to supply “work” phones to everyone, and so the Granstream WP810 came into my life.I liked this phone as a theoretical option, because it’s a one-device solution. End users don’t have to run cables to a desk-style phone, and they don’t have to connect and wire up a base station. To make it as easy as possible for our end users (if you’re in I.T., you know the tone of voice I’m using when I say “end users”) I collected the SSIDs and PWs from my test group of a couple of users, and set up the phones for their wifi in advance (and server/user settings, of course).WiFi entry is not fun, incidentally, if you have a long password (as I do). It’s basically late-90s-style text messaging entry. Not horrible, but if you have to set up let’s say 20 of these handsets you’re going to pull your hair out by the end. If you have hair. No judgement either way.I ordered a few of these WP810 handsets as a test run, and… just no.At home I have very good WiFi. As in I’ve never seen my cell phone or laptop just “drop off” the network for no obvious reason, and if I leave a ping open on my laptop to my gateway it drops 0 packets over the course of days.That being said, these phones would, while in their charging base, periodically make “bleep bloop” noises indicating that they disconnected and reconnected to the network. Occasionally I’d catch this visually, and that’s indeed what was happening. And it wasn’t my SIP server (at first I briefly panicked that it was), but I have a hard-wired desk phone that stayed faithfully connected.The call quality was also garbage. Don’t get me wrong, the mic and speaker are quite good. My codec is good. The phone’s ability to send out and process RTP packets in a timely fashion is the garbage part. Most of my devices at home are hard wired, so my access points don’t work very hard. This RTP issue would occur even when the APs’ stats showed no other devices utilizing bandwidth.Experimentally, I was able to place/receive/maintain solid call quality on my desk phone whilst the WP810s butchered the RTP stream. On a few occasions I took our morning team videoconference on my laptop (via wifi) while simultaneously calling in from the hardwired desk phone, the WP810, and even a GP720. The audio (and video for the laptop) was solid for all EXCEPT the WP810 which would consistently garble voices or occasionally drop calls entirely. Believe me, I wanted to know as much as you do that it wasn’t a) my wifi being of poor quality, b) my SIP server/datacenter’s network, or c) a specific faulty WP810 handset itself.The WP810 is simply not a good choice.To be fair, I don’t know if I can blame the phone completely. Wifi was NOT designed for VoIP. I mean, I guess ethernet wasn’t either, but it’s a heck of a lot more stable than a wireless connection (or should be… to each their own I guesss). And forget about it if one of your end users’ kids decides to torrent the latest and greatest of HBOMAX or whatever.My opinion is don’t get a Wifi phone unless your use case absolutely demands it.That being said, the WP810 is also feature-poor (yes, even with the latest firmware).Later I also tried out — and stuck with — the Grandstream DP720 DECT handset with the DP750 base.Holding both phones in my hands, the DP720 has a better feel first off. Its screen looks nicer (though the layout and information is much the same). When going into the menus of both phones, the WP810 disappoints. It easily has half the options of the DP720, and that’s ignoring anything Wifi- or DECT-specific respectively.More importantly, DECT is designed for voice (and some other stuff). It doesn’t share bands with your Wifi, so it doesn’t matter if you’re streaming 4K Netflix (oops, I mean Amazon Prime Video) on your tablet and downloading the latest patch from Blizzard on your laptop. As long as your actual internet bandwidth is higher than your (real-world usable) Wifi bandwidth, you won’t have any issues with voice quality.Battery life is also significantly worse on the WP810 than on any of the DECT phones I tried (including a couple of Yealinks). Not sure if that’s the phone itself, or (more likely) one of the differences between DECT and whatever Wifi protocol you happen to use. The phone constantly checking in with the SIP server isn’t that power-efficient, let alone when on a call.The nail in the coffin for me was that there is NO [practical] WAY to remotely administer the WP810. If you’re in my situation, you’d have to remote into a computer on the end user’s site, then use a browser on their computer to access the WP810’s configuration. (I mean, I suppose you COULD talk the user through opening up a port on their router to the HTTP(S) web interface of the phone, and if you’re lucky talk them through firewalling it so only your own network has access to that port, and then have them install some kind of dynamic DNS software….. just no.The Grandstream DP750 base (as well as the Yealink W60B, which I also tested) supports OpenVPN. I now have all my users connected to our internal VoIP network via VPN, meaning I can access each and every base station from the comfort of my couch without having to worry about the user’s network.In summary, if you need a cordless VoIP phone for yourself or your organization, do NOT buy this phone (or any Wifi phone) unless for some reason you absolutely cannot use a DECT base/handset combo.In its defense, the WP810 does in fact support QoS and has separate settings for SIP and RTP. That’s nice, but unless you know your Wifi network (and/or the rest of your network) will pay any attention to the QoS flags, it’s neither here nor there. That probably still won’t help if your access point gets saturated and its poor little ARM processor can’t keep up with all the traffic. My point being there’s too many variables in a Wifi connection.So far most of our users are happy with their DP750/720. I set them up in advance to be 100% plug and play, and did not have to intervene with a single person to help them set up their phone. So it matched up to the theoretical benefit of ease-of-installation that the WP810 provides.We have one user that is still using a WP810 (their landlord provides them with Wifi and no access to a hardline), and they hate it. I’m looking at other options for them.
It was greatLove it 😀
Works very wellDoes exactly what you’d expect it to do: it’s a wireless SIP phone that connects to a PBX using your WIFI. I don’t know what the complaints are about. I initially used the keypad to setup the WIFI and SIP connection, but it’s too cumbersome in the end. Best to use the integrated web server, which is very snappy BTW.
not reliable for me so far. but I love grandstream stuff usually.unreliable wifi connection I think since the audio keeps cutting in and out.

Works very well!I am very pleased with the Grandstream WP810! I have been using them for years. I have it configured with Callcentric and this new phone works well anywhere on our 1/2 acre property! Also will use it traveling! Never miss a call!

not good speaker when in handfreeThe speaker is not clean and clear when handfree mode.setup wifi at begining step is really challenge

Working as expected (Connected to provider through Mi-Fi) No lagging and good call quality, so farWorking as expected (Connected to provider through Mi-Fi) No lagging and good call quality, so far.Testing each phone component and feature. Inbound External call and also Outbound.
Horrible ProductYou can’t enter a “0” as part of the wifi network password and they provide ZERO tech support to individuals. Do not buy!

Achtung!! Funktioniert mit neuer Firmware nicht mehr vollständig hinter einer FritzBoxIm ersten Moment scheint alles gut, Top Telefon, super Sprachqualität, sogar in WLAN-Netzten funktioniert das Roaming. Solange bis der Akku leer ist und das Gerät vom Strom war bzw. aus- und wieder angeschaltet wurde. Dann kommen nämlich keine Anrufe mehr an. Man muss dan auf Werkseinstellungen zurücksetzen und dann geht es wieder bis zum stromlos. Nur mit neuer Firmware!,eine älter 1.07.85 funktioniert. Die wird aber nicht mehr herausgegeben. Der Hersteller weigert sich die Firmware zu korrigieren, FritzBox sei ja nur ein ThirdParty Produkt, hieß es

ExcellentVery solid product. Excellent voice quality and stability.Would advise everyone to use the Web interface for configuration as doing it through the handset is a pain.
