VOIP Phones Reviews

VoIP Phones Reviews

I just wanted to take a minute and review my experiences with some of the SIP devices out there on the market. I hope this post will help newbies or someone considering a certain device. I would appreciate any other input on either the devices I am "reviewing" or other devices that I didn't!

These devices are deployed in our primary line and small PBX replacement service provider offering.

Alphabetized && added GXP-2000 — KES

Hard Phone: Atcom AT-530
Good: Price, excellent voice quality, better for enterprise user
Bad: bad package , same hoursing with Atcom AT-320

Price: About $60 US

this one is the latest version ip phone of Atcom, use infineon chipset instead of pa1688, and voice quality perffect,
support 2 sip server same time, support full duplext speaker phone and 3 ways confefence.

More of my findings are on the Atcom page.

Hard Phone: Atcom AT-323
Good: Price, European Dial tone in the european version, very good 2-line alphanumeric LED display
Bad: badly distorted WinWord *.doc file as documentation (no PDF!), tiny buttons, Ethernet LED blinking at the front of the phone, slow operation, very user-unfriendly web page.

Price: About $70 US

I got one of those phones for a test, I tested it in a SIP environment. The web setup of the phone was not exactly what I would say "user friendly", I was not able to get it up.

Only after I opened the phone, saw that it uses the PA168 chip, searched the web and found web site of the chip producer, The chip producer had better documentation online than the phone producer.

I have now 2 Grandstreams and one Atcom and would prefer the Grandstream over the Atcom.

More of my findings are on the Atcom page.

Hard Phone: AZTECH V500DP
Cost $99 AUD
Rating: BAD (AVOID)

Well we bought a heap of these units in the office due to claim they are dect gap complient, so they could fit into an office solution (trial)

Well when you plug them in they default to fwd.pulver.com and I do believe there are several thousand units in OZ doing this. I decided to ring AZTECH USA, AZTECH CHINA, AZTECH HONGKONG and there subsiduaries to get some help as the voip selection is missing from the menu.

In short there staff where rude, run you around in circles (I was told at one stage that I hadnt paid my account) and yet the best one was - I was told to fly to hong kong to get my configurations checked.

On one unit the DECT complient DECT GAP also was not working, when I tried a handset that was DECT GAP Complient it didnt work, and no one from AZTECH was offering any help.

I am currently looking for an upgrade firmware and procedure to make these things works, but in the meantime beware. Aztech USA has refused to help and referred me to Singapore, where they cant speak english. Been speaking to another party who bought these units, is also telling me of horror stories about how there dealings with AZTECH was similar.

Feel Sorry for Pulver.....

When I try to email them with more faults I get this reply

Hard Phone: Cisco 7960
Good: Great looks, speakerphone
Bad: Price, Cisco stupidity
Price: About $250-300 US

I still use my personal 7960 phone in Skinny mode because it refuses to load the SIP load that I had to PAY for from Cisco. Cisco's directions to load the SIP load do not work and are outdated. After tinkering with a friend for half a night I finally got it to load the SIP image from the TFTP
server... which it then promptly rejected with a "checksum failure". I can handle buggy upgrades if I can access different firmwares for free, but to pay for a firmware that won't even load? No thanks.

The speakerphone is by far the best speakerphone I have ever had on any phone, ever. I use this phone when I do training conferences and meetings that are broadcast via teleconference, and it performs like a champion. The phone has good looks and is definitely an eye catcher. I have a couple of them set up in our administrative offices as "eye-candy". The later SIP versions work well.

Interface Card: Digium TE-405P
Good: Price, Intel-based, Features
Bad: ???
Price: $1500

Not really a SIP device, but I am very pleased with the TE-405P's that we have been buying from Digium. We interface them with our PRI and CT1 circuits and they are working without any problems. The price is right, they work with Linux, and they support every form of T1/E1 out there. What more could one ask for?

Hard Phone: Grandstream Budgetone 101/102
Good: Call quality, Feature support, Ease of setup, Price, Firewall support
Bad: Buttons are crap, cheap looking, speakerphone
Price: About $60-70 US

I use this phone to do all my testing and as my personal SIP device. My biggest gripe of all is that if you attempt to "speed-dial", you will never succeed. The buttons require a firm and definite press to register. I fail 1 out of 10 calls on this device simply because one of the digits was ignored. On the plus side the call quality is very good and loud if you are on the handset. The price is right, and the phone is easy to setup. It also supports STUN, and plays nicely with NAT/firewalls, and has good codec support.

The mic is too close to the speaker on speakerphone, and there is noticeable echo if speakerphone is used. The speakerphone is also too quiet, even at maximum volume. Customers call it the "walmart phone" — it is the cheapest looking SIP device out there.

Hard Phone: Grandstream GXP-2000
Good: Appearance Sound Quality, Basic Phone Features, Price, Codecs, Web Interface
Bad: Speaker Phone, Buttons, Call Parking, LCD Control
Price: Around US $100

If you have one of these get the latest firmware.

Decent looking phone. Handset sounds good. Good Codec list: ULAW/723/729/GSM. Web interface is trivial to comprehend

Speakerphone inadequate terrible echo cancellation. Call Parking on Asterisk requires callback / awkward.

We have serveral of these in production environments. The Latest GS Firmware is a drastic improvement over 1.0.*, and even improves the speakerphone somewhat. The buttons are a bit cheesey. Newly documented TFTP setup is a good start. Latest firmware improves Web face sanity.

Hard Phone: Linksys SPA921
Link to review: http://www.voipsyndicate.com/reviews/Linksys_SPA921/index.html
Price: Around US $120

Hard Phone: Polycom SoundPoint IP 500
Good: Price, Quality, Features
Bad: Does not officially support Asterisk, No STUN support
Price: $160-$299

This is a top quality phone. It supports G.729 and G.711. Has an EXCELLENT speakerphone (You may have seen Polycom speakerphones in your board rooms at work). Support PoE, VLAN tagging, XML config files, TFTP, FTP remote config, WEB interface, straight forward UI,l arge graphical LCD, 3 line appearances. The list goes on and on. I also have a Cisco 7960, but for the money I would take the Polycom any day.

ATA: Sipura SPA-2000
Good: Configuration, Functionality, Stability
Bad: Unimpressive Codec Support, Doesn't handle firewalls well
Price: About $85-95 US

Of all the SIP devices we have in the field, we have the most in Sipura SPA-2000s. The configuration is clean and straightforward. The Sipura definitely has the functionality that we need, and all features and functions seem to work well, and properly. The units are stable and do not
need constant rebooting or maintenance. Built in echo cancelation works well.

Unfortuantely, the lack of any decent low bit-rate codec is making me look hard at the Handytone 286/486 units (they support iLBC). The code in my Sipura's does not support GSM or iLBC. They also do not handle firewalls well at all. NAT support seems to work okay with Register's set frequently, but with no Stun support (they may have added Stun support in later firmware
releases), "real" firewalls can interfere with the device receiving incoming calls.

Soft Phone: SJ Phone by SJ Labs
Good: Interface
Bad: Configuration, No Echo Cancelation
Price: Free to Try

I've installed and quickly uninstalled many soft phones, but the SJ Phone stays on my test machine. The interface is clean and works well.

Unfortunately, the SJ phone is not very straightforward to configure the service provider information with its nested profile setup. There is also no echo cancelation code. I can't blame the SJ Phone for the echo, it's caused by a cheap sound card interface in my laptop, but it would sure be nice to find a soft phone that would help me attempt to cancel it out. The sound controls on the SJ phone are also poor, which exacerbates the echo problem.

Hard Phone: Tornado M5 IP Phone
Good:Unique Features, Interoperability, Interface
Bad:SIP based

Coming soon: Review of Cisco ATA-186 (if I can ever get it to work correctly) and the Grandstream Handytone 486 (have some on the way).

Hard Phone: Welltech 302 Lanphone
Good: Large Buttons, Price, Easy configuration
Bad: No LCD backlight, No STUN support
Price AU$150
