D-Link V-Click Dual Mode Phone

D-Link V-Click GSM/WiFI Mobile Phone

D-Link V-ClickThe D-Link V-CLICK allows users to switch between cellular and Wi-Fi networks with the click of a button. With a simple press of the V-CLICK button, the phone activates or deactivates the Wi-Fi connection that allows users to access websites or an Internet phone service, enjoying the convenience of reduced communication costs, faster transfer speeds, and increased productivity resulting from dual-mode phone access.

D-Link V-Click Design

D-Link V-CLICK phones boast a sleek, polished black compact form factor (h 4.17″, w 1.73″, d .75″), with additional colors planned to fit any lifestyle. The V-CLICK phones support Opera MobileTM, a mobile browser for logging into Wi-Fi hot spots, web surfing and email functionality on the V-CLICK’s two-inch (176×220 pixels) bright color screen.

D-Link V-Click Features and Functionality

For regular cell phone coverage, the D-Link V-CLICK phones will be “unlocked” allowing users to use their existing SIMs and pre-paid SIMs from traditional GSM cellular service providers anywhere in the world. By pressing the V-CLICK button, users activate a configurable wireless and SIP profile. Multiple profiles are available that make usage between home and office automatic.

  • Tri-Band GSM (900/1800/1900 Mhz) and 802.11 Wi-Fi (2.4Ghz) Access
  • Wi-Fi Profile Roaming for Uninterrupted Service between Wireless Zones
  • Opera Mobile Browser for Hot Spot Log-in and Web Surfing
  • Large Color Screen Display with 176 by 220 Pixels

D-Link V-Click First Impressions

Although dual mode technology is not yet offically supported by any stateside cellular provider, the D-Link V-Click is really a cell phone with VoIP as a feature – essentially you are purchasing a cell phone that supports WiFi with the ability to configure SIP settings. The real gem of dual mode technology is seamless mobility, the ability to move from one network to the other “seamlessly”, and that is something that is still a ways off. With a price tag of $599.99, the D-Link V-Click is on par in terms of pricing when it comes to cell phones, but for a WiFi phone, it is uber-pricey. In general, this is an exciting step in the right direction, and if you are in the market for a cell phone that looks to make VoWiFi is easy, this is the device.

The Linksys VoiceSystem 9000

We’ve all read the statistics on the increased use of VoIP in 2006 and how 2007 will be a break out year. This week I will introduce the Linksys Voice System as a way to cut the expense of traditional telephone service for the average Joe, the small business. Why Linksys? Linksys is a lot more than just a great name in the industry. The value of this system is due to the system flexibility and quick convergence it offers customers.

With the Linksys LVS-9000, you can make your small business look big, with an increased ability for customer communication and efficiency for your business.

But Art, why can’t I find “LVS-9000”, “SPA-9000” or even the search term “9000” on the Linksys web site? It’s true, those are all nomenclatures associated with the Linksys voice system, and no you’re not doing anything wrong. Linksys has made the LVS-9000 product suite available to small businesses, pre-provisioned for VoIP calling service by Linksys authorized partners who have demonstrated comprehensive product knowledge and are positioned to support small businesses during the installation process . There are a variety of VoIP service options to choose from, with leading providers participating, including Inphonex.

The Linksys LVS-9000 is designed as a “hybrid” solution. You may integrate up to (4) traditional analog (POTS) lines via the Linksys SPA-400 FXO gateway. Small business users may also incorporate VoIP calling services from affiliated network service providers, with a range of available options including:

• Outbound Call Termination Services
• Local, Long Distance, and International Calling
• Inbound Call Origination Service
• DID – Direct Inward Dialing
• Toll Free Services
• Voicemail
• Provisioning Server and Firmware Upgrades
• Tier II Technical Support

The Linksys Voice System 9000 presents the small business with a wide range of telephony features once only available to big business users.

My Experience with the Linksys Voice System 9000

Since this system is a few quarters old, I am probably not reporting anything new to some of you. Allow me to relay a customer experience I had this past week, to illustrate some of the key features of this diminutive, yet powerful IP PBX, and how it can assist you in meeting your business needs. I’ll also offer some insight into where and why I decided to fit the LVS-9000 into my customers business, as opposed to some of the other IP PBX’s out on the market.

Last week I was on a call with Acme Technology (name withheld for customer privacy), a small business with a total of six employees. The company was looking to replace their current centrex service with a simple IP PBX solution, and to leverage inexpensive VoIP service options to reduce their growing monthly Long Distance bills. After discussing the features they were looking for (Auto Attendant, Dial by Name Directory, Voicemail and Extension Call Forwarding), I suggested the Linksys Voice System 9000, as there was a fair chance their current headcount of six employees would grow to ten within the year (the SPA9000 is expandable to 16 users). Since Acme Tech. only had one IT person in-house, with no VoIP experience, the LVS-9000 was a good fit, offering simplified administration features like automated configuration of Linksys SPA-9XX series IP Phones. Acme Tech’s primary interest in VoIP was to realize cost savings, but they soon discovered that the Linksys LVS-9000 offered them a more efficient, feature-rich communications system and the additional business benefits of increased employee productivity.

I recommended the Linksys SPA-942 which would allow Acme to leverage their existing CAT5 LAN cabling. Because the SPA-942 offers dual RJ45 ethernet ports with an integrated switch, there was no need for additional network cabling to support the addition of IP phones. For faxing, Acme utilized one of the two available FXS ports on the SPA-9000 to support their analog fax machine (fax over ip). I also recommended keeping a couple analog (POTS) lines for local outbound calls and redundancy. The SPA9000 has no onboard FXO ports, therefore to support the POTS lines we added the Linksys SPA-400 4FXO gateway. The SPA-9000 dialplan was configured to route local calls to their analog lines, and long distance calls via their VoIP service provider. The Linksys SPA-400 gateway also includes a voicemail server with USB storage media port, which allowed Acme to host their own voicemail.

Illustrating the SPA-9000

View Acme’s network diagram below, illustrating the SPA9000 implementation. (eat your heart out Monet):

Linksys LVS-9000 Solution Cost:

(6) SPA-942 IP Phones = $900
(1) SPA-9000 IP PBX = $400
(1) SPA-400 Gateway = $300
(1) Talking with Art on the phone = Priceless (Yes, corny I know – but Miller Light just stopped doing their “Man Law” commercials with Burt Reynolds. If someone knows of any good commercials currently airing out there please let me know)

Acme’s total hardware cost was $1,300.00, or $216.00 per employee. Acme expects positive ROI within 1 year of installation, due to a dramatic decrease in their monthly long distance calling charges since moving to a VoIP service provider.

Additional Comments

As VoIP technology and related services like SIP Trunking continue to evolve, I believe that the need for analog (POTS) lines will steadily decrease.

This is another example of a customer’s reaction to the Linksys 9000 Voice System.

Jason’s blog above and the customer I was assisting this week both capture very realizable and positive results when implementing this system.

Governmental VoIP Adoption Missing the Mark

January 23, 2007 by Garrett Smith

arlyn piferFinally, here it is my first “official” blog entry. For those who are more experienced than I in this medium, feel free to critique, comment, criticize and add to the conversation. We are entering this with eyes wide open.

The focus of this blog will be centered around Voice over Internet Protocol, but with an emphasis on Government, (domestic and international) and Educational, (also worldwide), installs, intentions, forecasts and opportunities and I’ll spice it up with some plain old Arlyn based thoughts and comments.

Look, my real job, (you know – the one that semi pays the bills), is to sell VoIP systems and solutions to those two market segments. I’ll try my best to keep the postings unbiased and non sales focused, but if I slip from time to time, don’t forgive me, call me on it! Let’s discuss the contrasting opinions.

Well now that we know who is in the Super Bowl and in two short weeks we get to see those multi-million dollar commercials, let’s turn our thoughts to cost savings – and I’m talking about cost savings in the millions, in the multi millions, heck even billions of dollars. Two and one-half years ago, Kenneth Brown, from the Alexis de Tocqueville Institution, published a study and estimated that savings from, “federal, state, and local savings from VoIP deployment would equal $4.5 billion annually.” He adds “This is a conservative estimate.”

Conservative!? (a nice oxymoron for the current political climate in the US).

Two years later, ITAA published a listing that’s reads. “Savings could eventually reach $3-10 billion a year, according to Kohlenberger. “The federal government is the largest telecom user in the world, it stands to gain the most significant benefits in the world.” In addition to the savings, government customers will gain power and speed in telecom administration.” http://www.itaa.org/isec/headline.cfm?ID=2277

Now, it’s 2007, average inflation rate for 2006 was 3.24%, adding in some additional “fudge” factors and Arlyn’s estimate is that the US federal Government, State and Local Agencies could save a combined $ 12 Billion Dollars a year from VoIP acceptance and implementation. They could buy 2400 minutes of Super Bowl Ads or they could send every US Citizen a $ 40.00 refund check! (right before the next election).

Next time, we’ll discuss some of the reasons why the implementation hasn’t progressed as rapidly as it could have/should have.

Garrett Smith, approached me about creating a blog that had to deal with VOIP in the government and education sectors. I am not now, nor will I ever claim to be the expert in this particular filed, or any other field for that matter, but if you care to come along for the journey, maybe we can identify additional opportunities or learn something together. It is my intention to provide editorials and commentary and to locate and announce some useful websites. In addition, any articles or commentary of interest will be posted. I’ll also relay some of the cool implementations of voip in those sectors.

Skype Announces New Calling Plans

January 18, 2007 by Garrett Smith

Skype’s New Pricing is Anything But Disruptive

In a move to better monetize their service, Skype today announced a new connection fee for international calls, and a new plan, SkypePro, that offers a flat rate monthly fee for free nationwide monthly calling. Touting their new pricing structure as “distruptive,” for most Skype users the only thing distruptive about these new calling plans is the additional money that will need to be spent on connection fees.

While Skype is still one of the cheapest ways to make a phone call, the PR spin on charging customers more for the same service is, well, laughable. There are times for spin and there are times to tell the truth. Everyone knows Skype is a business and everyone knows they are in business to make money. Be up front about it. Don’t tout “disruptive pricing” and “Taking Internet Communications One Step Further With New Pricing Strategy”, tell us, the consumer, that the gravy train is over and we need to start to pay. Be honest and open.

Here are the facts of the new pricing structure:

New connection charge (3.9 eurocents per call)
Skype Pro calling plan for some countries (Flat Rate)
Select regions receive 1.7 eurocent per minute global calling

From the looks of this, and other moves, the “land-grab” is over. Skype is now looking to monetize of all of the subscribers that have been using the service for free, now that they are either hooked-on it or have seen the value of Skype. Great for Skype, not so great for infrequent users. It had to come sometime….

Polycom IP430 IP Phone Review

Introduction to the Polycom IP430

The Polycom IP 430 is an enterprise-grade IP phone, The SoundPoint® IP 430 is designed to meet the telephony needs of general business users – cubicle workers that conduct a low-to-medium volume of calls – by delivering a robust feature set encompassing traditional telephony features such as call, park, pick-up, hold and transfer, as well as more advanced capabilities such as shared call / bridged line appearance, multiple call appearances, and presence.

Polycom IP430 Features

The Polycom IP430 is a two-line desktop IP phone that delivers the outstanding voice quality and smoothness of natural two-way conversations with its full-duplex speakerphone featuring the Polycom Acoustic Clarity Technology.

• 2 lines
• 132 x 46 pixel graphical LCD with line LED indicators
• Full-duplex speakerphone with Acoustic Clarify Technology
• Intuitive user interface
• Robust feature set and security
• Integrated Power over Ethernet Circuitry (IEEE 802.3AF)
• Dual switched 10/100 Mbps Ethernet ports
• Built-in auto-sensing IEEE 802.3af PoE support
• SIP

Polycom IP430 Product Packaging and Documentation

The Polycom IP430 was packaged well and came with all accessories. Documentation consisted of PDF files I downloaded from Polycom’s website.

One thing I noticed about the IP 430 itself is that there is no special notched Ethernet jack like Polycom phones of the past. This type of jack could only be used with their special included notched Ethernet cable. This special cable would be used for Power over Ethernet or as a point where a wall power supply would plug into. The Ethernet jacks on the phone are ordinary, which means that readily available ordinary Ethernet cables are used.

Polycom IP430 Administration, Configuration, and Use

I used the voice over ip phone’s internal web pages to initially configure the phone to get it up and running quickly. The five sections of this page are titled Home, General, Network, SIP, and Lines. The settings on these pages are enough to register the phone and make calls, but more settings can be changed by using configuration files with an FTP server instead. The phone can also be configured through its LCD screen.

Polycom IP430 Asterisk Integration

The version of Asterisk used for this review is 1.4 beta 3. I used vsftpd as an FTP server for configuring the phone via FTP. The phone came with SIP firmware version 1.6.7 and bootrom version 3.2.1.0012. I found out that Polycom allows for the downloading of older versions of SIP firmware from its web site. The most current versions of SIP firmware and bootrom files are only available to Polycom channel partners.

I downloaded a zip file for SIP firmware version 1.6.7. This zip file contains sample configuration files, the SIP firmware, and locale specific files. The home directory I used on my FTP server is /home/PlcmSpIp. I edited the configuration files as needed by referring to a SIP admin guide downloadable from the Polycom web site. After rebooting the phone, the new settings in the configuration files were not being used on the phone. I found out after some more reading that any settings entered via the phone’s internal web pages would override the FTP configuration files. I found a way of erasing these internal phone settings through a menu entry. After rebooting the phone again, the phone took the settings from the FTP configuration files.

The FTP configuration files have many changeable settings. Changes I made included SNTP time sync, turning an audio MWI off, assigning an extension for retrieving voicemail, and making both of the two line appearances active on the assigned extension.General features such as call transfer, call forwarding, conference, and do not disturb all worked fine.

Polycom IP430 VoIP Service Provider Integration

I don’t use VoIP service providers myself. I had no problems getting the phone to be used as an extension on my Asterisk PBX and dialing calls via Ma Bell.

Polycom IP430: The Good

The best thing about the Polycom IP 430 is it’s mass deployment and configuration functions. These features are found on other phones too now.

Polycom IP430: The Bad

Dialing a SIP URL is possible only by using the twelve key number pad. Many key presses are needed to get an output of one letter, which is inconvenient. Entering a SIP URL would be better accomplished by using an internal web page instead.

One of the phone’s PDF files I was reading said the phone has instant message functions. Composing or replying to an incoming instant message is possible only by using the twelve key number pad. This text entry method has the same problem that entering a SIP URL does as a result.

Overall Impressions

The phone sounds as good as other similar IP phones I have used. I recommend this product.

Linksys WIP300 Wi-Fi IP Phone Review

January 17, 2007 by Garrett Smith

Introduction to the Linksys WIP 300

The Linksys WIP 300-NA Wi-Fi IP Phone enables high-quality voice over IP (VoIP) service through a Wireless-G network and high-speed Internet connection. Connect at home, your office, or at a public hotspot, and make low-cost phone calls through your Internet Telephony Service Provider.

Linksys WIP 300 Features

The WIP300 Wireless VoIP Phone operates in the 2.4GHz band, supports 802.11g and the latest VoIP SIP protocols. The large, full-color high resolution display features an intuitive user interface enabling users to easily and quickly configure the handset using Secure Easy Setup (SES).

• Pixel-based display—Provides intuitive access to calling features
• Nine speed dials configurable in the set
• Comfort noise generation (CNG), voice activity detection (VAD), adaptive jitter buffer, and echo cancellation
• RF and battery level indication
• Local phone book
• Embedded 2.4GHz antenna
• ABS+PC plastic housing
• 1.8” COLOR TFT LCD with backlight
• Simple keypad with backlight
• Remote Firmware upgrading via Wi-Fi
• SIP v2 signaling protocol, RFC-3261
• POP3/SMTP E-mail access (optional)
• SMS (optional, by system default)
• USB charger interface

Linksys WIP300 Product Packaging and Documentation

The Linksys WIP 300 is packaged well in a small box, with plastic packaging to prevent the phone and battery from moving around. Documentation consisted of a quick start guide on paper and a full user guide in the form of a PDF file on a CD. I didn’t read either one since the onscreen menus were intuitive enough to get the phone up and running. An electrical charger is included too.

Linksys WIP 300 Administration, Configuration, and Use

The administrative/configuration interface for the WIP 300 is similar to that of a typical cell phone, in that every menu function is squeezed into the small space of two soft keys, directional keys, a small LCD screen, etc.

You have to get used to the menu structure of the phone and how the buttons operate. There is an easier to use internal web page too that can be used to view or change settings.

Linksys WIP300 Asterisk Integration

I was able to connect the Linksys WIP 300 to my wireless equipment with no problems. For the review, I have a Buffalo WBR-G54 802.11g wireless access point/router. Since my WBR-G54 is not my primary firewall, I had to set it up as a quasi access point to ensure that the WIP 300 and my Asterisk server were on the same subnet. I setup the WIP 300 with manual IP address settings since my own network is generally an exception to the rule. Most often, a wireless VoIP phone would get its IP address from an up-steam DHCP server. This would be the case if a wireless access only product with a separate DHCP server is in use or a wireless access point/router that has its own built in DHCP server is used instead.

Wireless settings were programmed as 802.11g only, a hard to guess preshared key and SSID, WPA encryption, TKIP, and no SSID broadcast. These settings were programmed into one of the default profiles on the WIP300.

Settings for SIP registration were programmed into MySQL for realtime integration. I programmed additional statements in extensions.conf related to other phones I have.

For the review, I programmed my primary desktop IP phone to always forward incoming calls to the Linksys WIP 300. I was able to receive calls with no problems during this test.

Linksys WIP300 VoIP Service Provider Integration

I don’t personally use a VoIP service provider myself for any long distance calls. I have a traditional Ma Bell phone line instead for any local or long distance phone calls. The phone had no problem acting as an extension on my Asterisk server, so I was able to make local and long distance calls as I normally would on a desktop IP phone.

Linksys WIP 300: The Good

The phone is small, lightweight, and would function well as a secondary IP phone. Sound quality was good on the call flow tests I made. A test of sending and receiving email messages via POP3 and SMTP worked well.

Linksys WIP 300: The Bad

The battery cover easily slid off when I handled the phone in my hand.
The cover reminded me of one found on a TV remote control. The latching mechanism needs to be improved.

A blind transfer function test didn’t work properly with Asterisk. I made a call from the WIP 300 to one of my two desktop IP phones. I put the call on hold from the WIP 300 and dialed the other desk phone, then pressed the transfer soft key. I answered the second desk phone. Audio only went only one way between the two desk phones. A similar blind call transfer initiated from the desk phones went fine. There may be a problem in the SIP or RTP implementation of the WIP300. An upgrade of the firmware (1.00.07) and bootloader (1.00.02) didn’t solve this problem. The version of Asterisk for this review is 1.4beta2.

The Linksys WIP 300 does numerical dialing only. This will probably be the case for most if not all wireless IP phones of this type. I tried to dial a SIP URL from the keypad or the speed dial list, but was unable to.

I am not sure how well the battery will perform over time, so further tests of this type would need to be done. I was unable to perform a wireless roaming test since I only own one wireless access point/router.

Overall Impressions

The phone functioned well overall and I recommend it.
