Excellent call quality, Great Phone application interface
The KX-UT670 is the executive Android ( 2.2 ) IP phone in Panasonic's line of KX-UTXXX models for the hosted/open source market. This phone has no hard keys. Like some of the other Android based VoIP desk phones we've seen - the Grandstream GXV3175 and the CloudTC Glass 1000 come to mind - the KX-UT670 relies solely on its touch screen for user input.
Impressive and cool looking 7 inch touchscreen phone
The Panasonic KX-UT670 demonstrates how using an open platform like Android enables useful third party apps like TouchDown and LightTouch Reception. Besides the ability to customize and develop apps for the KX-UT670, the ability to control up to 16 PTZ cameras certainly gives this phone some niche applications such as a security desk or even an executive's home-based IP phone used when working from home.
Works great, but took some effort to get it to link to a remote TFTP server
The phone works exactly as advertised. I needed to set this phone up to work as a VOIP extension at a remote office. I needed it to connect to a Talkswitch 848VS (talkswitch is now owned by Fortinet). When all the settings are correct this device works great.
The reason I am not giving this device 5 stars is because the directions that came with the phone did not explain how to set up the phone in the manner that I needed.
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.
I purchased these items for both our US and European Operations so I could video conference with my other traders. Upon receipt of this device and upgrading the firmware to the latest it just got stuck. You wait three days to get customer support. End result they say send it back.
If you want to spend more time trying to get a device to work than actually making money using it, then get this phone. Going with Siemens. At least when you have a problem the turn around time is ONE HOUR !
Touch interface needs improvements
Whether you're on board with combining Flickr and desk phone or not, the GXV 3175 is an exciting product. The Internet browser application is the best one we've tried on a desk phone to date. GXV 3175 to GXV 3175 video calling worked seamlessly (no surprise), and there is evidence that video will play nice with others as well. The phone offers so many features that I'm sure we left a lot of stones unturned. Is it perfect?
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.
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.
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.
