Linksys SPA8000 8-port Analog Telephone Adaptor

The Linksys SPA8000 is the latest in the line of VoIP adapters from Linksys. The SPA8000 features eight RJ-11 FXS ports to connect analog telephones to IP-based data networks and includes a single multi-port RJ-21 50-pin connector offering an alternative connection choice when deploying the telephony gateway in varied environments. The device also has one 10/100Base-T RJ-45 Ethernet interface to connect to either a router or multi-layer switch.

Allthough the SPA8000 is a step-up in size for Linksys, who has until now played in the residential VoIP adapter sector, the greatest benefit of the SPA8000 is that it offers all the key features and capabilities with which service providers can provide customized services to their subscribers. The SPA8000 can be remotely provisioned and supports dynamic, in-service software upgrades. A secure profile upload saves providers the time, expense and hassle of managing and pre-configuring or re-configuring customer premise equipment (CPE) for deployment. The SPA8000 is “built” for large scale deployments needing a VoIP gateway.

Grandstream GXP-2020 First Impressions

The GXP2020 is the second phone in the GXP Enterprise SIP Phone portfolio. The GXP-2020 represents a much needed upgrade in the looks department. Grandstream, which has been criticized as a maker of low-end, low quality products, has REALLY done a great job in the past year of changing that image. While their products remain value priced, their quality and corresponding return rates, are far superior to that of many of their competitiors. With an MSRP of $169.99, this phone will probably hit the streets in the $149.99 range, and with the overwhemling amount of features, and improved design, this phone will certainly give Polycom, Linksys, and even Cisco a run for their money.

Polycom IP 550 Desktop IP Phone

In addiing the HD Voice capability, backlit display (finally!!!), and XHTMl capabilities, the Polycom IP550 is poised for the next stage of VoIP calling. With an MSRP of $369.99, the phone is certainly pricey, but will probably be found in the $339.99 range , “on the streets.” For that price and with HD Voice, not widely support, you are best to wait for other options, unless of course, you are working with an unlimited budget.

IP PBX Solutions for Your Business

March 16, 2007 by Arthur Miller


Voipsupply offers a variety of different IP PBX platforms. The platforms serve a wide array of customers and range from sophisticated enterprise solutions like Cisco CallManager Express to branded asterisk solutions for small to mid sized offices, or even small and home office do-it-yourself bundles that feature open source free pbx software like Trixbox. All platforms offered have optional provisioning and support available. Several of the platforms are also supported free of charge by the respective manufacturer.

Provisioning, “the dirty work” can be applied on a general level or detailed level depending on what features you need for your PBX. Christopher Heinrich, head of provisioning states,

“The majority of customers who wish to have their IP PBX provisioned send a document containing the desired extensions of the phones and the names associated with those extensions. We also have customers who prefer to set this up at a later date but need assistance setting up call groups prior to shipment.”

The majority of platforms available, in particular asterisk-branded solutions such as Fonality or Switchvox can be shipped at a nearly plug-and-play level, even allowing old extensions from prior phone systems to be used again for a smooth transition into your new system.

Support is also broken down into a general or granular level which usually depends on the technical level of the consumer. Support ranges from a 48 hour e-mail response time to a specific engineer dedicated to assisting you over the phone with any questions you have on usability or implementation. Pbxselect also works with local installers around the U.S. and Canada that, “connect the dots” after the systems ship for customer installation and training.

A sampling of the platforms offered:

  • Switchvox – This is a commercial IP phone system built off Asterisk, with an intuitive GUI and lots of other features built in. It comes in (2) versions, SOHO and SMB. The SMB version also has a desktop user utility, a JavaScript application, that allows users to see the presence of other extensions logged into the system, and allows you to drag and drop calls to extensions or voicemail boxes. You can also find third party applications that hook into their API. One current application uses Google maps to automatically populate an address and picture of the location calling you based on the area code and dial number of the incoming call – neat stuff!
  • Fonality – Also a commercial IP phone system built off Asterisk. It is slightly more expensive than Switchvox but the graphical user interface is a lot more depth. See below for a few links/demos:

    The HUD demo is very worth checking out, I suggest you try it!

  • Rhino Ceros / Trixbox – This is a bundled open source VoIP PBX has put together with Rhino Equipment, which runs of their server and TDM hardware, in conjunction with Trixbox. This system is by far the most flexible in our offering. It ships out of the box ready, with the Rhino PCI card and works with all SIP compliant IP Phones. If you care to spend time fine tuning the system you can get very advanced features for a very low cost.
  • Talkswitch – This is a key system replacement that includes both PSTN and VoIP capabilities. Works with analog and SIP phones, very simple to set up and administer. The best thing about Talkswitch is that you can use the system in multiple locations *without* needing to have a service provider in the mix – the PBX’s will simply connect to each other over the broadband connections at each office.
  • Cisco Callmanager Express – Pbxselect is a Cisco Authorized Premier Partner with Callmanager Express specialization. Many hundreds of successful systems have been deployed using Cisco Callmanager Express; more detail on this solution is probably not needed due to its immense popularity.

Aastra Telecom Podcast

Aastra Telecom’s New Line of IP Phones Have Been a Huge Hit!

Aastra’s latest line of IP Phones have been flying off the VoIP Supply shelf these past few weeks and this week Jon Arnold, in his Canadian IP Thought Leaders series, features Aastra Telecom’s Executive Vice President Yves Laliberte. Aastra is based in Toronto, and is one of the leading business telephone OEMs, for both legacy and IP markets. Yves addressed the current state of the market, and compared the differing paths that enterprises and SMBs are taking as they adopt IP.

He also focused on the importance of Open Source and SIP for enabling more flexible and feature rich solutions than were possible in the TDM world. Finally, Jon and Yves talked about the road ahead, and how Unified Communications and FMC will be driving the market, and how that will impact vendors like Aastra.

Marketing VoIP Services To Non-Technical Consumers

Not All Consumers Understand VoIP

But you do not HAVE to make them fully understand the technology in order to get them to interested enough to purchase your VoIP service. You do, however, have to give them enough information and understanding of Voice over IP in order for them to be confident in making a buying decision. Here are some tips you can use, as a VoIP Service Provider, to help bolster your marketing efforts in order to increase your subscriber base.

VoIP Service Provider Marketing Tips

  • Speak The Customers Language – Do not use tech speak. Keep acronyms to a minimum. If you had to tell a ten year old what it is that your company does, how would you describe it?
  • Don’t Use High Speed or Broadband Internet to Describe an Internet Connection – 90% of consumers do not know what broadband means or if their service is high speed, after all, even dial-up services promote a higher-speed product. Instead, use DSL or Cable to describe the Internet connection necessary to use the service.
  • Sell Devices That Mimic The Traditional Calling ExperienceVoIP adapters, while cheap, add a foreign device to the calling experience. Rather than wasting your time explaining what an analog telephone adaptor does, sell them and cordless IP phone. Customers are familiar with cordless phones and people like things that they are familiar with. It will save the time and headache of explain why you need and ata and how to install it. If you insist on having a VoIP adapter, make sure you offer one that has PSTN failover, like a Linksys SPA-3102 or Grandstream GS-488.
  • Explain What Happens When Their Internet Connection Goes Down – Do not just make this a bullet point in the fine print. Use it as an opportunity to differentiate yourself from your competition by explaining the issues and making sure your customers have a “back-up” plan such as a cellular phone or PSTN line for failover. Sure you might lose a customer or two, but the ones you gain will trust you. Trust build loyalty. Loyalty breeds lifetime customers.
  • Show Them More Than Price – If the sole decision was price, then they would have switched year ago. Most non-technical customers needs reasons other than price savings to go through the “hassle” of switching their phone service. Promote the convenience of voicemail to email, how they can use a second number so others can call them for free, educate them on the benefits your features provide them.
  • Do Not Make Switching a Hassle – No one wants a hassle. Make the sign-up process easy, have knowledgeable staff answering your phones, have a number porting system that constantly updates the customer on what stage of the number porting process they are currently in. Make sure devices arrive on time.
  • Make Paper Invoices an Available Option – Believe it or not, many consumers WANT paper bills. Due to their “non-technical” nature, they may not be use to or comfortable with paying bills online. Do not make them do it “your way”, allow them to do it “their way.”
  • Stop Assuming and Start Talking – Stop assuming you know what customers know about Voice over IP. I “thought” I knew what people knew about VoIP, but it wasn’t until I started selling VoIP in a brick and mortar retail environment that I started to “get it.” From there, I actually paid a friend to go out and get people to fill out surveys about their knowledge of VoIP. What I found was that most people know little, are filled with mis-conceptions, and really do not care about VoIP. But do not take my word for it, go out and talk to lots of people about Voice over IP.

While it is one thing to identify points that VoIP service providers need to market to, it is another thing to execute on them. Execution, after all, is just as important as strategy. These points are merely a starting point for enhancing the marketing of your VoIP service – do with them what you will.

Digium TC400B Transcoder Card

March 2, 2007 by Garrett Smith

Digium’s TC400B Trandscoder Card decrease CPU processing load

digium TC400BOne of the most costly uses of CPU load on a server running Asterisk centers around the transforming of the G.729a codec into other codecs for the purposes of call origination or termination, bridging disparate calls, or VoIP to TDM connectivity. As you may well know, though, these transformations in software are very expensive, in terms of MIPS, and require a substantial amount of CPU time to accomplish.

That is why Digium has released the TC400B. The TC400B was designed to relieve the CPU of these processing duties, freeing it for other tasks (or allowing you to use a less powerful unit), and also allowing Asterisk to bridge G.723.1 compressed audio into other formats. Prior to the TC400B, you did not have this capability.

Digium TC400B Functionality

The TC400B decompresses G.729a (8.0kbit) or G.723.1 (5.3kbit) into u-law or a-law; or, compresses u-law or a-law into G.729a (8.0kbit) or G.723.1 (5.3kbit). The TC400B is rated to handle up to 96 bi-directional G.729a transformations or 92 bi-directional G.723.1 transformations.

Digium TC400B Benefits

In addition to the relieving the CPU of transforiming processing duties and allowing Asterisk to bridge G.723.1 compressed audio into other formats, the Digium TC400B does not require additional licensing fees for the use of these codecs nor does it require the registration process associated with Digium’s software-based G.729a codec licensing. An additional cost and time savings!

The Digium TC400B ships with one TC400P and one TC400M voice processing module. It is currently shipping and is retailing for $1499.99. For more information or to order, please visit the Digium TC400B page.
