which is the Best IP Phone.

Use a soft phone if your agents have PC's, you will save a ton on money opposed to buying hard phones.

Hi,

We use a lot of the Aastra phones, especially the 9133i. They have good voice quality (running ulaw/alaw) and are sturdy enough for high usage.

Hi,

We installed a small call centre for a client using soft phones and USB headsets. Everything worked fine until the PCs got busy then the voice started to break up. Adding extra RAM to the machines fixed the problem but it is something to keep in mind when using soft phones.

Hi

Sorry but never heard about usb headset, can u give me some link where i can check it. or how it works?

Nischal..

Any major electronics retailer should have them. Search for USB Headset. I just checked Radio Shack and Best Buy and both list several in the $30 - 60 range. These would be fine for testing. For production use you may want to go with a GN, Jabra or Plantronics, available at places like hellodirect.com etc. Assuming you are using a Windows 2000 or XP client machine, there is usually no installation at all. You plug 'em in and they show up as a new sound device. I use one all the time on idefisk (IAX softphone) and they work well.

I refuse to use Polycom because of their support policies. Trying to get firmware is like trying to pull teeth. Tell them you are using Asterisk and they refuse to talk further to you. Basically your at the mercy of your reseller/distributor and they BETTER have a good legit relationship with Polycom.

IMHO you cannot go wrong with Aastra. They will support you directly and are VERY supportive of the Asterisk community. After using their phones in a production install I realized that good manufacturer support is almost as important as a good quality phone.

You can easily get them for $85 each including shipping, taxes. Bought eight of them with no trouble whatsoever.

4 lines, perfect quality, robust keys, very configurable, beautiful, perfect.

I wouldn't buy anything else.

The GXV-3000s on the other hand, by the same company, Grandstream, are not that hot -- the keys are flimsy and there aren't enough programmable keys, etc. I'd wait for a revision on those phones.

The newer GXP-2020s also are something I would avoid until the price comes way down.

All other phones I researched give you less for more money compared to the GXP-2000s

I believe the question was "which is the best ip phone" not "what is a cheap medicore entry-level phone".

Grandstream simply owns the market on the low-end. Their phones work and are inexpensive but can certainly not be considered equal to a Polycom and they don't position them that way. To say a GXP-2000 has "perfect sound quality" pretty much shows you have not done a side by side comparison. I am not saying to not buy Grandstream phones, but they are simpy not "the best" but in many cases they are "good enough".

Snom is the next step up the ladder and might have edged up even more except my personal experience with them actually puts them below Grandstream because of the vast number of problems I have had with them.

Linksys moves the bar up a notch. The SPA-9xx phones are rock solid, easy to configure, sound good, are priced decent. However, they are pretty basic on functions that even the cheaper Grandstream phones have. Overall though, one of my favorite phones.

Aastra phones have really grown on my lately. I had a 480i CT on my desk for a long time and have replaced it with a 57i CT. The XML services are second to none and the new phone works great and looks terrific.

Polycom phones are by far the best sounding phones available today. That is the main thing they are known for. They can be a real pain to get the setup working the way you want, but once you have it, its pretty easy to replicate. With trixbox 2.2, we will have support in the Endpoint Manager for Polycoms making them really simple to setup.

While the other points are mostly valid points about other phones, there is just no comparison to the quality and performance of a Polycom. If they are out of your budget, then you just start moving down to other vendors but you should be fully aware of what you are getting in to.

A Cisco, Polycom and Snom. All are mid-range and support the same basic functions. The Cisco has a huge screen comparatively and a nice MWI. Voice quality is damn good. Other than that is very hard to install and maintain... again comparatively.

The Snom is really very nice, a little cheap feeling, but is holding up. Very easy to set up.

The Polycom is truly sweet. A little harder to set up then the Snom and a few fewer features for the price point. As geeky as I may be, I still buy phones for one real reason... How well does the unit sound. The Polycom [in my environment] sounds the best. Provisioning is supported. For production it is what I specify for now. Subject to change of course.

Kerry,
You really should take another look at the Snom line. The first one I bought was horrible with interface problems and putting a call on hold was about like playing russian roulette. However.... With the latest firmware installed:

Kernel Version: snom320 linux 3.25
Application-Version: snom320-SIP 6.5.8
Rootfs-Version: snom320 jffs2 v3.36

My snom 320 has become my favorite phone, with some of the best audio quality I have heard to date.

The Grandstream GXP2000 on the otherhand, while MUCH improved over what it was a year ago still has audio issues. The function of the phone is great, the audio sucks. It works fine for occasional use, but would drive a call center operator nuts after a while (I am running the latest beta firmware) They are getting closer, but have not hit the mark yet.

I have installed the Polycom IP501 and the Uniden. I think the Polycom Phones sound Very Very Good. The Mic reception for speaker phone is great and the volume does not cut out during a conversation. Would recommend.

I have got my myself connected with a phone manucfacture. No i have our own phones and i am using them without any issue . also i use them at client place.
www.r-mad.com for the models

I have good quality IP phone range for 50 to 80 USD.

I think the fact that Polycom is actively involved in this forum now should raise their "value" considerably. Polycom is all that we use (15 now, 14 more in next 2 months).

AASTRA Phones work great because they have a headphone port already on the phone. I connected Plantronics Office headsets right into the RJ-11 port , worked fine

I like the Polycom 500/501 phones, personally. They look nice, have a solid feel, and are very user-friendly to the end-user. The ability to add a logo to the display is a nice touch, especially for the phones in public areas like reception and conference rooms.

Sound quality is fantastic, and I do not kid you there. When I first started exploring a softpbx solution for our office, I was very concerned with sound and call quality--I was afraid it would not be up to par and would prevent deployment, despite its flexibility. My first test phone was a used Polycom 500, connected to the PSTN with a Rhino R4FXO card. It SOUNDED BETTER than our existing, traditional Panasonic phone system. Speaker phone sound quality is also superb, again better than our existing Panasonics.

Before committing to Polycoms for our phones, I tried a Grandstream GXP-2000. The price point for that phone was attractive, but the phone wasn't. Sound quality was okay, but the look and feel of the telephone itself came across as cheap. Since we're a professional firm, I couldn't deploy a phone like that anywhere, except maybe a break room or storage room.

I will echo the sentiment that Polycom phones are a pain to provision--I spent a couple of days playing with my first one before I finally figured it all out. Needless to say, I'm thrilled to hear that Polycom is now working with the Asterisk community, and more thrilled to hear that a Polycom Endpoint Manager has been completed (now get TB2.2 out of beta!). Once you get them figured out, it's not so bad, but I still wouldn't look forward to deploying any significant number of them.

@Roadkill:
Why?
Health concerns could be a legitimate reason...
DECT is famous for its strong microwave radiation!

I have tried Polycom phones (hands down best, in my opinion, but very expensive) and several Grandstream phones, and the Grandstream phones were just adequate until the GXP-2020 was released. It has very good sound quality and features, is much heavier and more professional looking than the GXP-2000. Firmware updates are plentiful and it is the easiest phone to integrate with open source trixbox/asterisk/freepbx. However, if you need more line appearances, Grandstream has yet to release an expansion module for the 2020, and the 2000 expansion module will not work with the 2000.

I have 12 phones and one expansion module on an open source (FreePBX) system. All except 4 of the phones are GXP-2000; the four are GXP-2020. I paid a mere 124 (free shipping, no tax) for the GXP-2020 phones. They accomodate standard 2.5mm jacked headsets.

I have also experimented with softphones (I even paid for a pro version!), and have to agree with the previous posts re: voice quality on a USB headset.

I have used Linksys, Aastra, Cisco and Grandstream.

I let my clients try them out and they usually choose Aastra.

Cisco: Too expensive and difficult to setup for SIP
Grandstream: Too cheap and with that goes the quality (For personal home use or really small business with budget issue may get by with them)

Then both Linksys and Aastra attracts most of the people due to their price range and quality. Linksys phones are actually made by Sipura and if you have used Sipura ATA devices you'll know. On the other hand, Aastra used to supply Nortel with phones which were then branded by Nortel.

Sound quality: both of them are great but for feature sets for the same price range Aastra 9133i usually wins over SPA942.

I am installing one cllient with 60 Aastra phones, 1 with 19 and another one with 5 - All Aastra phones. Over $3000 in savings just not going for Polycom.

I've never tried Polycom's IP phones as well as SNOM. I can see a lot of good remarks on Polycom but when I give the clients options to choose, they all go for Aastra for the price-quality ratio and I agree that for the money they save, maybe not having the 'Polycom' audio quality, is still worth the investment. I do usually tell all clients that Cisco is the leader in the IP world and in the $400 range, Polycom is the leader for teleconference sets and best audio quality in $200 range and Aastra or Linksys in sub $150 range.

I can only see Polycom getting into lot of these small/medium business only if they bring their price down to close to Aastra or Linksys. I am sure for a few bucks more most people would then turn to Polycom. Until then I think Aastra will continue to win business based on perceived 'voice quality/price = value' ratio

Just my 2 cents.

i use and recommend snom, absolutley easy to set up , and packed with features

I have Trixbox 2.4.2 running on a mini-ITX fanless computer behind a Linksys wireless router (DD-WRT Linux O.S.) and that's behind a Comcast cable modem (Surfboard 5120). I have two ITSP accounts. One is with Callcentric.com and the other is with Broadvoice.com. The Three IP phones on my network are the Grandstream GXP-2000, Aastra 480i CT and the Polycom 650 IP. I first bought and used the GXP-2000 about a year ago and thought "Wow, this thing is great and has tons of features and lines". I was satisfied but it would lock up every now and again and I had to pull power to get it to right itself. It was a little light and cheap feeling too. Then, I wanted another IP phone but with cordless capability so I opted to get an Aastra 480i CT and I was blown away by the improvement. I was impressed with the quality, dense feeling of the handset and loved the way it would answer a call as soon as you grabbed it out of the cradle without having to hit the talk button. The base unit is equally nice with a great look and sound quality and the XML is impressive. You can hit the buttons you have programmed to get area code information, stock quotes, "This Day" information, ESPN or CNN news headlines and the list goes on and on. It sounds great too and I was glad I got an upgrade instead of another GXP product. To round out the low to high end examples of phones for my customer demonstration system I have for prospective IP PBX users/customers, I found a great buy on a week old Polycom 650 IP from Craig's List and jumped on it for $200. I always used to roll my eyes when I'd read how great they sounded. But when I got it on my system and started making and receiving calls, I was and still am blown away at how awesome it sounds, feels and looks and hence all this writing. I've demo'd my "setup" to two clients so far and they all want the 650 or the 550. The setup isn't as easy as the others but it's not hard at all. Oh, the Polycom admin login is "Polycom" and password is "456" by the way for you serchers. The ring tones are super smooth and "professional" sounding. The HD codec, which I think is just G.722 sounds WAY better than the same codec on my Grandstream so Polycom must be doing something different. When I demonstrate the above equipment at a customer site, they'll make calls on the two ITSPs using the GXP 2000, then on the Aastra 480i CT and finally on the Polycom 650 IP and after they hear the quality of the 650 they always get this big smile on their faces and always vote this phone as the best. Polycom is the best and the 650 is their top of the line product at this time. Thanks for reading. Matt, mattcero@gmail.com

Grandstream GXP2000, running 25 or so for a year now. I also purchased some snom 320's at the same time, The snom phones definetly takes the prize and user preference in our office environment, they are worth the extra $$. However for home only use the the Grandstream would be adequate. (they just doesnt stand up to heavy use) I havent had any experience with the other models suggested above. Grandstream failure rate 1 in 10 units, I havent had any failures with the snom phones.
