Excellent audio quality, Responsive touchscreen display
The VVX 500 has a standard set of hard keys: a numpad with round buttons that are large and satisfying to use, buttons to control volume, activate headset, speaker, and mute, and finally, a button that takes users to the main 'Home' screen on the touchscreen display.
A full featured IP deskphone in the $40-$50 range
The GXP 1405 is lightweight and compact. Depending on what you're used to, the hardware quality may leave something to be desired. For example, the base and handset could feel a bit hollow to you if you're accustomed to the thicker plastic found in Polycoms.
Very good sound quality
Where the KX-UT113 succeeds is where it actually matters: voice quality. The speaker phone is nice and crisp. It renders both speech and IVR menus quite well. It's no Sennheiser, but it's leagues ahead of the execrable speaker that came with our pre-production UT136. The distortion control kept everything smooth sailing even when we blasted music through one phone line to try to overdrive the phone's speaker.
Changes made in web admin portal pushed to phone immediately
Speakerphone quality has also been noticeably improved. When we reviewed this phone with firmware version 00.0032, we found a distracting amount of white noise whenever we switched a call to speakerphone. We're no longer experiencing this problem with firmware version 01.133.
An excellent VoIP Phone
Well, this Cisco phone is one of the top model in Cisco business series desk phones, so its no brainier that should work just fine. I have done my homework before purchasing it and I am very pleased with the quality of the calls. The phone is very easy to configure since it has a WEB API to work with. Compare this with 7xxx series of Cisco phone where it is almost impossible to configure the phone without Cisco call manager, this is piece a cake to work with.
An Excellent SOHO Conference Phone
The following is a summary excerpt from a longer review published March 23, 2010. The complete review can be found here: [...]
There simply aren't very many comparators against which to judge Polycom's SoundStation IP5000. Most dedicated IP conference phones target larger conference situations, and cost considerably more.
There are a few small conference phones available from lesser known companies, but in this price range these tend to provide only analog or USB interfaces.
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.
Cannot recommend Grandstream
We used this and several other Grandstream voice and video phones for about a year before giving up on them. Grandstream phones are about the lowest cost IP phones available. They will work as a basic voip phone, for dialing and receiving calls. That is about all I can say that is positive about them. If you want to use ALL the latest VoIP and PBX features, Grandstream will leave you wanting. The firmware is buggy and features often don't work correctly.
Very affordable, Feature-packed
We were impressed with this phone, which is no surprise considering that we also liked the GXP 2020 when we reviewed it last year. The GXP 2100 does just about everything comparable VoIP phones from competing manufacturers can do at a fraction of the price.
