Should Cisco Kill the Linksys Brand?

Note:  Om has a nice write-up about the possibility of discontinuing the Linksys brand just as AT&T has absorbed Cingular into "The New AT&T".  I use this term loosely of course.  I think overall it would be better to have their product line under one name as long as the Cisco Quality goes along with the entire line.  I have purchased some Linksys networking gear lately and I have had hardware issues on simple pieces of gear that you would think would work right out of the box.

"Cisco Systems, apparently is facing a dilemma: whether to lose to the Linksys brand name or not? Cisco bought Linksys a couple of years ago for $500 million, and it has been a good addition to the portfolio, expanding Cisco’s reach into consumer, SOHO and small and medium sized business markets. (Read: Cisco’s born again consumerism.)" 

CEO John Chambers has expressed his wishes many times to phase out Linksys brand, and just consolidate everything under the Cisco moniker. He reiterated the same in Europe last week. (See video on YouTube via UberPulse.)On the corporate blog, the company is saying the two brands can co-exist.

We can make jokes about CEO being the last one to know, but we won’t. Our friends at Light Reading think that Cisco should shank the Linksys name. eWeek thinks they will be shooting themselves in the foot.

Configuring Asterisk to support a T1 PRI connection

Asterisk provides an open source solution for those who want to deploy VoIP in an organization, but don't want to invest a lot of money in a proprietary solution. After you get the software installed on a server, you have some more work to do. You have to connect your server to an outside voice line. In this article, I'm going to show you how to set up the Asterisk Soft PBX system interface with a T1 PRI connection.

Afterwards, you should be able to install a Zaptel-compatible PRI card, configure it for your needs, and modify your Asterisk dial plan to begin making outgoing phone calls from your internal SIP phones, as well as receive phone calls over your PRI line to your SIP clients.

Author's note

There are many different options for configuring your outgoing trunk, and it's impossible to cover all of the options in the scope of this article. What will be covered is the most common configuration in the United States, which is for a T1 PRI. I recommend that you become friendly with your sales/support representative and tech support, as you should ask questions about what the channel stepping method is, encodings, and D-Channel.

Ooma Designed Hardware Offers Free Domestic Calls

A Silicon Valley startup wants to shake up the telecommunications industry with a $399 gizmo that provides free, unlimited domestic phone calls for homes with broadband Internet service.  Ooma Inc. will also offer a free second line, conference calling, voice mail service and an online "lounge" where users may change their preferences or get voice mail in an e-mail format. The company will start selling the devices Thursday with an invitation-only offer to select U.S. residents.

The company _ backed by $27 million in venture capital _ eventually hopes to crack the home-based and small-business niches. Engineers are working on a system that forwards calls to cellular phones.

"It's nothing like anything a carrier can do currently," CEO Andrew Frame said. "Once you own the box, you don't have to pay ooma anything in the future."

Frame and other executives assume, of course, that their company won't meet the same fate as other startups going up against telecommunication veterans.

Earlier this week, Internet phone carrier SunRocket Inc. abruptly shut down, leaving more than 200,000 customers scrambling for alternate service. The No. 2 standalone Internet phone company after Vonage Holdings Corp. attracted customers with cheap plans and innovative features, but traditional phone and cable companies also lowered prices and started bundling their services.

Open Source Phone System (VoIP) Thriving at UPenn

The Philadelphia-based Ivy League university, University of Pennsylvania, currently has over 1,250 Session Initiation Protocol (SIP) IP phones on desktops, tied to a back end based on SIP Express Router -- an open source VoIP call-control and routing stack, and Asterisk for voice mail messaging. Don't go away! This is just the start. The University has extending the VoIP network in to a 15,000 seats, in it's plans!

Deke Kassabian, the university's senior technology director for information systems and computing, plans to grow that installed base by a factor of more than 10 over the next five years. Driving the project is the desire to get off costly Centrex monthly fees and infrastructure, and the promise of an open source, standards-based VOIP infrastructure that provides superior integration and control.

"If we can run one modern IP network for voice, video and data .... there's a clear win," Kassabian says. "If we provide business telephony internally, less money leaves the university."

The Linux-based SER call control and Asterisk messaging servers were a better fit with UPenn's standard back ends for authentication (Kerberos and RADIUS), its OpenLDAP directory structure, and e mail. While commercial IP PBXs are adaptable to these platforms, "they don't work that way out of the box" typically, he adds.

With open source running extensively throughout the university -- from directories, to e-mail, DHCP and DNS -- the level of expertise in open source troubleshooting and development was there to support the Asterisk plans, Kassabian says.

"For years UPenn has had a strong open source talent pool. As a result, we have the staff and expertise to develop and roll out open source VOIP."

UPenn's work with the Asterisk community is also paying off by improving the product itself. University programmers have already contributed to two additions to the code base, which is now supported in the main release. One change integrates IMAP-based voice mail and messaging stores, and another involves improvements in SMDI signaling between IP phones and voice-mail system back end.

QoS - Voice Quality Management for VoIP Networks

Network managers generally focus on quality of service (QoS) as the only means of monitoring and managing the quality of IP services. But while managing packets for loss, jitter, or delay is important for VoIP networks, today's successful VoIP providers must go farther; they must ensure a high-quality customer experience by monitoring and managing voice quality levels.
In fact, the quality of voice reproduction and transmission can often make or break customer satisfaction and service renewals. In this article, we'll look at IP voice quality challenges along with a new class of solutions for this challenge.
 
Why Standard QoS Isn't Sufficient for Voice Service providers typically use three techniques to control and enhance QoS in packet-based networks: class of service (CoS), differentiated services (DiffServ), and Multi-Protocol Label Switching (MPLS).
 
All three have one thing in common: they all attempt to minimize packet loss and jitter of the voice transport. While this is one piece of the puzzle, controlling packet loss and jitter does not prevent other impairments from degrading the voice. CoS (IEEE 802.1p) is the usual means for providing QoS in Ethernet networks. With CoS, all packets are assigned a priority, and VoIP traffic generally receives the highest priority; thus, using CoS prioritization can minimize VoIP traffic packet loss.
 
DiffServ is a class-based IP QoS technique specified by the Internet Engineering Task Force (IETF). The DiffServ Control Point contained in the IP header is used to control the Per-Hop Behavior (PHB) of routers along the traffic's path from end to end. With VoIP traffic, the PHB is normally set for "Expedited Forwarding" to minimize latency and packet loss.
 
MPLS adds a separate 32-bit header to each packet which is used to create virtual label switched paths (LSPs). With LSPs, providers can segment, prioritize, and expedite traffic. Originally created as a means to implement virtual private networks (VPNs), the MPLS header also has a 3-bit QoS field that can be used to minimize packet loss and latency with VoIP traffic.

Free Email to Voice via VoIP Calling Launched - Yoomba

 

Yoomba has launched an application which turns email messages into VoIP calls. The service requires a small download which adds 'click to call' buttons to the user's email messages and address books, which when clicked will send a message to the contact including a link.

When the recipient clicks on the link, a VoIP call is set up between them and the Yoomba user and they can begin chatting.

The idea is to remove the need to log into a third-party program when setting up a personal VoIP call, although this is also achievable through company VoIP networks which could even include special handsets attached to the computers.

"We think this is the only way it [VoIP] will reach mass adoption," said Yoomba's chief executive Elad Hemar.

The service integrate the 'click to call' buttons into many major email programs, both online and offline, including Microsoft Outlook, Gmail, Hotmail and Yahoo! Mail, which should make it easy for users to quickly and simply get in contact with their contacts over VoIP.

Truphone Wins Court Injunction Against T-Mobile Blocking Tactics

Editor's Note:  I bet this is being appealed as we speak.  
 
Competition in the mobile telephony sector intensified today when a judge granted a mandatory injunction forcing T-Mobile (UK) Ltd to interconnect with Truphone, which provides a low-cost internet telephony service on mobile phones.
Core information
  1. T-Mobile was instructed by the judge to stop blocking and begin routing calls to Truphone numbers by Monday 23rd July.
  2. Today's ruling is the first time that interim relief has been awarded against a mobile network operator under the Competition Act.
  3. Full details of both sides' skeleton legal arguments are available [see links below]. The judgment is expected to be available electronically tomorrow [Tuesday July 17th].

Quotes

James Tagg, Truphone's chief executive officer, said:
  • "The injunction is good news not only for Truphone but for every company trying to develop internet-era services and for every consumer wanting freedom of choice and lower prices. We are determined to bring better-value mobile calls, text messages and other innovative services to mobile phone users, and it's right that we should not be prevented from doing so."
  • "To be granted interim relief means we successfully demonstrated that we have an arguable case to make at a full trial."
  • "We didn't want to go to court but we had no choice: T-Mobile was effectively preventing the launch of the Truphone service so we had to take urgent action."

Apple Patent Application hints at Wifi iPods

The U.S. Patent and Trademark Office has revealed a raft of new patent applications submitted by Apple's lawyers, covering new technologies for iPods, Web pages and mice.

Macsimum News spotted several patent applications that were filed months ago but just revealed this week on the PTO's Web site. The most intriguing example appears to involve a method for allowing an iPod or iPhone to talk to a neighboring device through a wireless network.


The application assumes that mobile devices already are capable of downloading data from the Internet over cellular or Wi-Fi networks, "however, as portable electronic devices become more versatile and more interactive, it is advantageous to exchange (send and/or receive) media or other types of data with other electronic devices in a wireless manner."

Digium Acquires Sokol & Associates

Digium just acquired Sokol & Associates the company behind the successful Asterisk training program and the Astricon trade show. This further reconfirms the idea of Digium being “everything Asterisk,” a concept espoused in a recent interview with the company’s news CEO Danny Windham.

“We’ve been such an active part of the Asterisk community for years that joining Digium seemed like the logical next step for our group,” said Steve Sokol. “We look forward to continuing to work with Asterisk users around the world and to taking our knowledge of how people are using Asterisk every day and using it to impact future product development.”
 
“Asterisk is one of the most commonly used open source projects today, and as the community of users and contributors grows, we want to deepen our relationship with them,” said Mark Spencer, founder and chief technology officer of Digium. “Sokol & Associates has run Asterisk training classes around the world and has long been a central part of this community. By bringing Steve and his group on, Digium gains another conduit to new and advanced Asterisk users around the world.”
 
So what does this mean for the future of Digium and Asterisk? Well Digium is the driving force behind Asterisk. The open-source communications market is getting competitive. By purchasing a well-known training company in the Asterisk space, Digium should be able to grow revenue nicely. This move positions Digium as a major training powerhouse. Acquiring Sokol & Associates is a smart move in my opinion.

Asterisk Based Plant Assistance : Pick Up Its Your Plant Calling

 
 
As promised, here's a Q&A with the co-founder of Botanicalls, a not-yet-ready-for-primtime product that enables houseplants to call you on the phone when they need attention. Of course they can't really call you, but four NYU grad students - among them, Kati London - have concocted a way to simulate a call.
KL: Kati London, welcome to TP. Mind explaining how and your co-horts, hahaha, have gone about giving plants a voice?

Kati: We wanted to do things as cheaply as possible, so we created a simple circuit. We start with rudimentary sensors that determine soil moisture levels in a given plant. We add little photocells to determine the plant's light levels. We connect those sensors to a little chip set with thresholds.

KL: Oy. Thresholds?

Kati: Yeah, like "I need water but it's not urgent". Or, "Hi, I'm desperately in need of a drink". Or, "Thanks for watering me but now there's water left in my dish. Could you empty it?"

KL: A pain-in-the-ass plant. I love it. Go on.

Kati: OK. The little chip is connected to a wireless radio, which is connected to a master radio, which is hooked up to the internet via an ethernet cable. Now the plant's communicating directly with a webpage. The webpage is Asterisk, an open-source phone system, which launches a call based on the info it receives from the plant, in a voice that's been pre-recorded.

KL: Pre-recorded by what, or whom?

Kati: Friends, actors, folks who we thought reflected the biography of each plant.

iPhone: The Perfect Asterisk PBX Companion

So, you didn’t get one, huh? Well, we did. Just goes to show that some folks don’t have much to do other than stand in line for 8 hours to claim what my wife has labeled “another stupid toy.” Yes, the ultimate iToy. Boys and their toys! Apple has had the better part of four years to perfect Mac OS X, and it shows in the iPhone.

So here’s our software report card: 
 
  • Synching, flawless
  • Bluetooth, flawless
  • Wi-Fi, flawless
  • POP3 and IMAP Email, flawless
  • iPod, flawless
  • Photos, flawless
  • Calendars, flawless
  • Address Book, flawless
  • Safari, flawless
  • Camera, flawless
  • The iPhone will take its place as one of the most revolutionary computers in the 21st century. And we think it may well be one of the best computers with one of the best computer interfaces ever delivered. But note that we said “best computers” not “best phones.” It’s an incredibly good travelling Wi-Fi device, and that’s probably how it will be remembered ten years from now. And AT&T. Well, they’re still just as lousy as they were 10 years ago.

    Before turning to Asterisk, we wanted to quickly review our iPhone chronology for those who are considering a purchase. Bottom line: buy it from Apple. We didn’t because they don’t yet have a store in the entire state of South Carolina. They still manage to charge sales tax for web purchases, however.

    Friday. Let’s start with AT&T. We arrive at a totally deserted store in the middle of a Mattress Factory strip mall at 10:30 a.m. on Friday. There are 12 people in line, the first six of whom are so-called iSitters, people paid a couple hundred bucks to wait in line for someone else. In our case, the #1 iSitter is standing in for Catherine Bell, the star of Lifetime TV’s Army Wives which is being filmed in Charleston. She arrives at 5 p.m. with her daughter in tow… in a brand new Porsche, of course. The TV crew promptly wets their pants. No one much complains that Catherine and her entourage assume their place at the front of the line. But, does the iSitter leave? Well, no. AT&T staff are totally clueless. They’ve been sitting in their (empty) air conditioned store all day doing absolutely nothing except turning down iPhone wanna-be’s asking to use the bathroom. “We don’t have one” is the stock reply. And the Store Manager’s one minute of fame consists of telling the ABC reporters that everyone in line will be taken care of “one way or another.” Turns out, most folks get the “another” option. The store gets 15 phones delivered in a book bag by an AT&T delivery truck at about 4:30 p.m. They don’t trust their employees either! So, for most of the hundreds who have waited, their only option is to wait another “two to three days” to have one shipped to them. Heh, heh. Anyone want to take that bet?

    Then there was the moment of truth. Six p.m. and the doors swing open for the first five in line. They, of course, make an exception for the Army Wives entourage. By the time they’re finished, there is one 8-gig iPhone and six 4-gig iPhones left. We snag one of the 4-gig models after AT&T recovers thirty minutes later from their first nationwide network implosion. They can’t even process a credit card transaction without a meltdown. Just another day for the A&T repair crews. With our iPhone in hand, we head out the door and do a quick package unopening for the local news crew. They’re thrilled. Then we’re off to play.

    Any Windows XP machine with the latest version of iTunes works with the iPhone. But, if you’re a loyal Mac user, you have an extra hurdle. Only the very latest version of Tiger works and you need the latest version of iTunes as well. If any of this were operating system-dependent, we could understand the limitation. But this appears to be a way to sell more Mac OS X upgrades. Back in law school, they called it tying. We decide to use Windows XP and skip the Panther-to-Tiger upgrade hassle.

    You register the iPhone and sign up for service using iTunes. The whole process takes less than 10 minutes and is flawless… at least for us. Remember, it’s not yet 6 p.m. on the West Coast. So the second wave of registration meltdowns has not yet begun. We decide to start off lean and mean to see how far 4 gigabytes goes. We load 500 songs, a couple of music videos, and 50 photos plus a dozen or so contacts just to be sure we have a stable system. We then add an IMAP email account and a gMail POP3 account. We still have a gig and a half of storage which looks pretty reasonable to us. We call it a night at midnight after a couple of quick calls to our Asterisk PBX. Everything works swimmingly.

    Mitel sues ShoreTel - What does it mean?

    Note: Tom Keating ran this blurb about this lawsuit. 
     
    Some fellow TMCers were emailing back-and-forth about the Mitel lawsuit against Shoretel just before Shoretel launched their IPO. A few moments later, Jon Arnold emailed me, a bunch of TMCers, Om, VoIPCentral, Ken Camp, Russell Shaw, and a few other bloggers & journalists about this bit of news and what it meant. Go check out Jon's post here where he makes an analogy to the Verizon lawsuit against Vonage, another VoIP player around the time of their IPO.
    As a result of the lawsuit, the ShoreTel IPO is up in the air.

    My email response to everyone in the thread was "Interesting indeed.. -that is, for mid-tier IP-PBX vendors fighting over the scraps that tier-1 IP-PBXs such as Cisco are leaving behind."

    And then you have up-and-coming whipper snappers like Asterisk and Asterisk-based solutions such as Fonality, trixbox, etc. that have continued to take more market share in the IP-PBX space.

    Andy wrote back "This is interesting and Tom's comment makes me think that we are at a point where innovation is slowing down."
