Best ip phone for the price Excellent device, it does what it is supposed to do.
We bought 10 pieces 4 years ago or more and they are working fine since then.

Good phone for small offices or tight budgets Deployed about 70 of these a couple years ago.
* Can't beat the price
* Good call quality
* It isn't butt ugly
* Easy to provision
* Speakerphone unusable in environments with alot of background noise, or if you are a meter or more away from the phone
* Power supply fails after a year or so, espescially if backlight is provisioned to remain on

Decent features, Horrible lifetime We bought about 25 of these as our first step into a VOIP system (Asterisk/Elastix). They worked fine for about 9 months, and then they started to fail. Phones would boot, but they were unable to detect the network connection. I have replaced about 10 total so far. Outside of the reliability, they do have decent features, and the call quality is pretty good.

Stay away We bought 25 of these Grandstream GXP-2000 phones. We have had them a little under a year, and so far 5 are completely defective, and possibly a sixth (which is what prompted me to write this review). When they work, they are decent. But they are only sold with a 90 day warranty, and with the money you will lose replacing the phones, spend the extra and get a better phone.
-When most of them have broke, they either do nothing at all, or flash the lights rapidly like a strobe light, like the phone is having a seizure.
-Two of them, the BLF (busy lamp fields) no longer light up when an extension is on a call, they just stay green.
-The phone claims it can handle four accounts, I have not yet been able to do it. I can get two, and once a third is added, it boots off the first account.
Besides these problems, they are fine for a cheap phone. The call quality is not awful. Half of these are used with the handset that comes with the phone, and half are used with headsets connected to the 2.5mm jack. Both sound equally as well.
We have had these phones on Asterisk, Trixbox, Fonality, and 3CX, all systems seem to be fine with these phones. All our phones have been hooked up through POE (POE switch, not injected), and work fine.
Bottom line, when they work, they are fine for a cheap phone. However, the failure rate is worth looking at a better phone.

Save Your Money Bought one and it worked fine so a few months later I bought another. A few months later one of them went down and refused to boot. I deployed the spare and it too went down and refused to boot. Tech support tried but was not help because they refused to acknowledge the phone would not boot. Kept sending me information on how to reset them once they booted up. The phones looked very sleek, sound quality was good and when they worked all was well. But for both of them to go down with the same problem within days of each other....I can't risk that again. Will pay extra this time to avoid GS phones all together. At the end of the day all I ended up doing was tossing $200 into the trash with these phones.

meh I've spent DAYS trying to make these phones happy. I bought 15 of them to deploy in my office since they apparently have the feature set I'm looking for. The biggest problem is BLF. They work fine if you only have a few phones using this function, but once you get any more than that it becomes sketchy at best.
Ideally, it would have been nice to have BLF monitor the execs in the company so that people answering the phone could see their line status. This just does not work. I've tried BLF, eventlist BLF, even just plain presence watcher. I did have eventlist BLF set up properly on the pbx.
The only BLF I can properly get working is monitoring with any scale is the parking lots, but even then - after about a day they also start to malfuntion. The ONLY fix is a power cycle - and no, reboot does not help.
This is a serious problem, and we lose calls, or park people indefinitely because of this.
I am not the only person encountering this, and the manufacturer doesn't seem to care.
* Blind transfers seem to drop calls more often than reasonable
* The ringtones that come with this phone's stock firmware SUCK. Seriously, they are horrible. The default one sounds like the tone you hear when calling out to somebody. It's fairly easy to replace them, with a little research - so at least there is that.
- Configuration interface is lacking.
- sip account name is plastered on the display of the phone, and there is no option to hide it or put optional text in it's place.
Some good points:
- Sound quality is great: both the handset and speakerphone are excellent. (hence the +1 on performance) Phones were used primarily with PCMU (ie G711u), but also tested with G729a.
- VLAN capability is nice (+1 usability), but no VLAN setting for the PC port (-1 usability).
- Price point is low (get what you pay for)
- Phones seem to be designed fairly well for durability.
These phones are low in value, buggy, and hardly supported or updated by their manufacturer. I will be purchasing new phones for the office, while these will get to go to field deployments where business PBX functions aren't as important. I regret having purchased them in the first place, and would trade them in for something else in a heartbeat is voipsupply.com's return policy allowed me to.
PBX: sipXecs, running on a virtual server in our vsphere cluster.
LAN: All phones on dedicated IP subnet within an isolated VLAN, 100% PoE powered.

It's the Mac of IP Phones Running a small business on a tight budget, we opted for VoIP in stead of a land line. We couldn't have hoped for a better phone for the money. The thing *just worked* (we're a Mac shop, and seriously appreciate the seriousness that accompanies that phrase). No complicated setup - as a matter of fact, I did the setup from the phone before I read the manual and found out there's a web interface - and had four phones up and running in under 20 minutes. It does what I need it to do, and I'm sure it does more, but for basic calling, transferring and conferencing - it's perfect.

Outstanding blend of function and cost effectiveness I use these phones in my home with an Asterisk server and I recommend them highly to my clients in home automation and integration installations. They work; as advertised... PERIOD! I was amazed at how simple the set-up was and how many advanced features were available from a "budget" terminal. If you want or need simply the best terminal for the money and you aren't looking for something that has every bell and wistle known to man that will work dependably, as advertised, PERIOD then this terminal is the best; and in the humble opinion of this CTO, the only viable option out there. Sure Cisco makes a great product and sure they do some kewl stuff, but if you want or need a terminal that is a rock solid performer and will not scare your employees or clients with its complexity, then not only is the GXP-2000 terminal the best choice, it is the only logical choice.

Great value We bought these for our entire organization. We're using Asterisk server. This is a great value.

VERY GOOD DEVICE It is a very good device though not very useful for hands free operation as the built in mic is not very sensitive.

Very Good Product Great product for those looking for an entry level office phone. Believe this phone will work fine in a typical office, but not suited for a warehouse or other non-climate controlled environments.

GREAT PHONE FOR THE PRICE!!!! My purchase was on time and the price was way cheaper than other places!!!!

Okay for personal use If you need a phone for testing or just to get started with VOIP it's great. I would not recommend buying these for business use. I've had every single power supply fail of about 14 phones within 20 months. Two phones died completely, 4 have broken back lights because of bad firmware design (fixed now) and 5 phones have intermittent audio problems. I've been slowly replacing all of them with aastra phones

Love my GXP I have tried a bunch of different phones that were a lot more expensive than Grandstream, and in my opinion the GXP-2000 is just about the best value going.

Best IP Phone you can buy under $100 I was looking for an inexpensive IP phone for our non-profit. I tried several models, ad the Grandstream GXP-2000 was by far the best phone I could find under $100.

Great Phone For the Price I have used this phone is several environments and find it to be a good phone for the price. It is easy to setup and has good sound quality.
