Doesn't play well with our auto attendant application
It's a bit premature to make closing statements about the Invoxia NVX 610. We love the idea, the audio quality is great, and the build quality of the device is clearly fantastic. However, if you're going to advertise a product as the 'Next Generation' anything, I would expect that you would include the features of the 'Previous Generation': Multi-call handling, Blind Transfer, Attended Transfer, Multiple SIP accounts, etc.
Great work phone
The form factor of these phones are both visually appealing and physically comfortable to work with on a daily basis. We are using them for a Ring Central account and the setup was a breeze - even for the non-technical people. I would make one technical recommendation to purchasers: these do not come with a power supply. If you are a medium sized or larger office (not just 1 or 2 people), then I would recommend purchasing a POE switch to power the phones instead of the $15 power brick.
Excellent audio, quality Intuitive to use
The Cisco SPA504G is a very good phone. With HD voice supported, it delivers excellent voice quality in an intuitive and well-made piece of hardware. The OnSIP team is thrilled to see another manufacturer taking steps to bring HD voice to midrange phones that won't cost customers an arm and a leg.
Cheaper than many other video conferencing hardware
The Polycom VVX 1500 is more than just a 6-line enterprise desk phone. It's a business multimedia phone, which is another way of saying that among other things, it supports video calling and business applications. Weighing in at over 5 pounds, this is easily the biggest and heaviest VoIP phone I've ever tested.
Stylish and easy to use video phone
The VVX 1500 has a great range of features and is easy to configure. Full support is currently limited under most SIP server platforms, but video call routing is easily handled via a TFTP contacts directory, so this doesn't put too much of a crimp on its usefulness. Unfortunately, at over Â£650 (exc. VAT), it's painfully expensive compared to any IP video phone on the market short of Cisco's Â£1,480 7985G.
Excellent audio performance, Very user-friendly
The IP 6000 looks almost identical to the older IP 4000 model, a phone that was released almost 10 years ago. I would have much rather preferred the redesign given to some of the other Soundstation phones - the IP 5000 and IP 7000 look sleek! The IP 6000 closely resembles a tripod, with a microphone at each of the three endpoints to ensure equal sensitivity to sound input from all directions (~4m microphone pickup range). A large speaker sits at the top for the ringer and audio output.
Works nicely for me
The review that gave this phone 1 star because of the PoE issue wasn't reasonable. To be clear - the phone does not come with a power adapter. You will need to buy one separately or use a PoE (Power over Ethernet) injector or switch to power the phone. I don't mind this at all - in some locations, it's easier to power it with PoE, and I appreciate not having to pay for an extra adapter I won't use.
This is not a consumer phone.
Item was not new as offered
The item was previously used but offered as if it were new. To set it up has been a big problem as it is password blocked so new firmware must be downloaded but the version managed by the phone is old so the one available it Cisco right now is not useful. I have not been able set the phone to use it as it should have brought at least the passwords stablished by the previous user/administrator.
Built-in volume controls and ringtones
Hawking Technology's Net-Talk is a USB "Internet phone," which is to say it's a phone for making VoIP calls with an existing Internet connection. The lightweight device is compatible with the four major instant messaging services that offer voice capability (AOL, Yahoo, MSN, and Google), but it's primarily designed to work with Skype.
Excellent build quality
In closing I'd like to return to an impression that I first had some years ago when I first started using IP phones. If you work for a small company, or in a home office, and live on the phone as much as I do, then life is just too short to get by with a marginal phone. You can't appreciate the difference between "good enough" and something that is truly exceptional to use without trying it for yourself. The difference in cost is not as much as you might expect.
Great personal and conference VoIP phone
I bought several of these phones for employees at my office last year. They've worked very well as office phones and even as conference phones with up to three people sitting around the phone. The sound quality is very clear.
There are a few caveats that apply to all VoIP phones. First, before you can use a VoIP phone you must configure the VoIP server, in our case Asterisk, to associate the phone's MAC address with its phone extension.
Excellent handset and speakerphone voice quality
The overall design successfully incorporates both sharp edges and rounded corners, and gives the phone a very sleek look. The Polycom 550 is probably one of the most visually appealing desk phone we've reviewed so far.
