ChanSkype: Skype And Asterisk Talk To Each Other
A Brazilian company has forged a software bridge between Asterisk and Skype.
Asterisk is an open source VoIP PBX that runs on Linux and other platforms which handles VoIP to VoIP calling as well as calls to landlines. Developed by Mark Spencer it has taken the community by storm, sprouting many tens of thousands of installations world-wide, with a thriving development community.
It can work with traditional telephony systems or POTS (plain old telephone system), with digital systems (ISDN etc) and modern VoIP protocols such as H.323, SIP, MGCP and more.
Digium (set-up by Spencer) now manufactures hardware and offers a commercially supported version of Asterisk known as ABE (Asterisk Binary Edition).
One feature that has been missing is Skype integration (the next version of Asterisk v1.4 supports GoogleTalk using Google’s libjingle library). A Brazilian company has now changed that, with their ChanSkype site.
ChanSkype
Currently the service is in test and you have to utilise ChanSkype’s own Asterisk servers. They offer a “free” trial whereby they allow a SIP connection and then by passing in a Skype address it sets-up a connection to the Skype user.
In the future they will be offering an actual chan_skype that plugs directly into any Asterisk server and can connect to the Skype network.
Of course it’s not quite so simple. The initial release only runs on RedHat’s Fedora Core or CentOS (which means it will probably also run on RedHat Enterprise Server too as CentOS is a clone of that). There must also be an X server running as well as the Skype for Linux client. So ChanSkype just bridges the two systems together.
A dual Xeon 3Ghz with 2 gigs of memory should run 30 simultaneous Skype calls without any noticable degradation of performance.
Pricing has not yet been set, but it will be licensed on a per-channel basis.
There may be licensing problems too as Asterisk modules should normally be available under a GPL license and with source code, but as Skype is proprietry they may get away with it.
Someone really needs to reverse engineer the Skype protocol and then a native chan_skype could be developed, but this is unlikely to happen in the western world as that could be illegal.
It’s a good idea, but really just a straight link into the Skype software which unfortunately is the only way it can be done.

Polycom Communicator Review: Handsfree Skype (83%)
The Polycom Communicator (C100S) first caught our eye at the Skype-day in London. It’s a well-formed handsfree speaker/mic kit that connects to your PC via USB, letting you make trouble-free calls on Skype.
Polycom aren’t new to the field of handsfree. You may well have used their SoundStation in telephone conferences. They’ve leveraged this experience to tune the Communicator to minimise feedback.
What’s it like to use
Getting it setup is breeze. When you’ve carried out the one-off process of installing the small piece of software on to the PC and authorised to allow it to work with Skype, you’re away.
We found it very easy to use, not only that, but were highly impressed with its performance.
Conversations flow more naturally, as if you were in the same room as the person, because you’re not holding a phone handset. The extra auto-echo-cancellation that has been built into it, also lets you use it without the other party realising.
For those who are keen on secrecy, there’s a standard 3.5cm headphone socket in the right by the mic.
When you’re travelling and need to make a series of calls from your hotel room, the Communicator will be a boon. Forget using the cellular with an ear piece, this lets you sit in your hotel room and make your calls while taking advantage of Skype’s low-cost calling too.
The Communicator also has a life beyond Skype calls. Due to its high quality speaker, it’s great to use to play your music through, or use during a presentation with audio in it. A great advantage.
Design
It’s a well designed solid piece of kit that’s had a lot of thought put into it. This is amply demonstrated by its surface-finish (which comes in either blue or grey), which just through its touch gives you confidence in it.
With its size being similar to two packs of cards sitting next to each other (3.24″ x 5.25″ x 0.85″/ 85 cm x 135cm x 25 cm), you would have no hesitation in chucking it in to your bag when you’re on a business trip.
The centre-top is dominated by a high quality (22 KHz) speaker, with twin microphones on either side of the bottom front corners. This not only gives excellent sound reproduction (actually beyond Skype 16KHz capabilities), but the dual mics make it easy for many people around a table to take part in the conversation. The microphones are independently balanced, so a person sitting a distance away from one would not be drowned out by another sitting close to the other.
The middle section of the unit has a collection of five buttons arranged within a circle. On the left is a blue Skype-logo’s button, that when pressed, makes the Skype software on your PC become active. The button on the opposite side of the circle connects and disconnects calls. Volume controls are at the top and the bottom, with a mute button in the centre.
Around these buttons is a circular LED that gives progress on the call – it flashes green when connecting the call, glows green when on a call and red when the conversation is muted.
The back is hinged to provide two features – holding the 79 cm (33″) long USB lead that wraps around the back, and to act as a stand for the unit when it’s in use. Like the rest of the unit, it too, has a reassuringly-solid feel about it, with a hinge that feels like it will last.
The intelligent design touches continues on this flapped hinge with its rubber corners, minimising movement where it rests against the table.
Summary
A great, quality device that works easily and well, providing you with a better way of making Skype calls.

USRobotics Adds Two Skype USB Phones
USRobotics has rolled out two new Skype Certified handsets, the oh-so-catchily named USR9601 USB Internet Phone and the seductively monikered USR9602 USB Internet Mini Phone.
Both phones plug into an available USB port and integrate with the Skype desktop application to provide “easy voice communications” to the Skype community.
According to USRobotics, the phones come with technology enhancements designed to get rid of the annoying echoes that plagued earlier handsets and banish the ‘orrible “tunnel” sound suffered on cheapo handsets.
Both phones – neither of which are lookers – come with an integrated keypad letting VoIPers make calls to Skype contacts via assigned speed dial numbers, or to dial telephones anywhere in the world with SkypeOut.
The more expensive of the two phones, the £30 ($49.95) USR809601 offers a high-resolution, blue back-lit LCD screen for contact information and call status, while the entry level ($24.95, £13) USR9602 USB Internet Mini hasn’t a single LCD pixel to its name.
“Our collaboration with USRobotics provides the growing Skype community with high quality, affordable Skype devices that make Internet communications easy whether you’re at home or in the office,” hyped Manrique Brenes, director of hardware for Skype.
“USRobotics and Skype are committed to enabling the world’s conversations; these new USB Internet phones are a great example of our shared vision,” Brenes added, while we pondered over how one gets a job as an “enabler of world conversations.”

Four Skype WiFi Phones Announced
The terrible day that the mobile phone companies had been hoping wasn’t going to arrive, is here. Skype have today announced four WiFi handsets that let you send and receive calls without switching your computer on while wanding around – err, like a mobile phone. They’ve been expected for a while, but are finally getting closer to the hands of the public, being as they’ll start selling in Q3 this year.
The big shift for these handsets are that Skype is embedded into the handsets, so the PC/Mac isn’t required to make calls, as has been the case with wireless Skype handsets to now, like the Siemens M34.
Speaking in an ideally sized, sound-bite sentence, Stefan Oberg, General Manager Hardware at Skype enthused, “We want to give people the freedom to move around while talking and have access to Skype wherever they are – whether in front of a computer or while moving around the home or office,”
The quad-bevy of handsets announced were
- Belkin WiFi Phone for Skype (F1PP000GN-SK);
- Edge-Core WiFi Phone for Skype (WM4201);
- NETGEAR WiFi Phone for Skype (SPH101); and,
- SMC Wi-Fi Phone for Skype (WSKP100).
NetGear SPH101
We got our hand on the NetGear SPH101 recently and were really impressed with the solid build and how easy it was to use. The Skype interface was loyal to the computer-based editions, with the graphics being an exact replica.
The only issue we found was, as it doesn’t have a Web browser built into it, it doesn’t have the ability to connect to Public Wifi points such as BT OpenZone or The Cloud, as you can’t log into them. Open access don’t have this problem and the expected encryption protocols are supported including WEP, WPA, and WPA2 with PSK support. We’d imagine that the inability to login via a Browser would be the same with all of these handsets. It’s unclear how long the battery will last when released, by NetGear were quite bullish.
The SMC handset is being made by a company that we’ve been speaking to in Taiwan. The OEM manufacturing deal was signed within the last week, so it shows how fast this area of the market is moving, seeing the Skype announcements coming so close on its heals.
Mobile phone companies are now having to live with the fact that, with sufficient WiFi coverage, people may not need to pay for their mobile phone calls in the future. Yikes!

Packard Bell EasyNote ‘Skype Edition’ Laptop: Mini Review: Exclusive
We played with the Packard Bell EasyNote ‘Skype Edition’ Laptop, at its first European showing yesterday. The machine we used was the only one in Europe and had been jetted in from development labs in Estonia.
They claim it to be the worlds first ‘Skype Edition’ laptop, and we’ve no reason to doubt them. While many machines have been selling with Skype pre-loaded on it, this is the first to have a dedicated button built-in to the machine.
If your reaction is, ‘so what? It’s a laptop with a soft-button on it,’ that wouldn’t have been too dissimilar to our initial reaction – before we used it. After having seen it action, our view is more favorable.
Where’s the button?
Our first surprise was to find the Skype button at the top of the screen, where you normally find the catch. We’d expected it to be on or around the keyboard.
As you can see from the close-up photo, the Skype button sits on the right, the microphone on the left and in the centre is a video camera, a la new Mac laptops. There’s an LED between the mic and video camera and another surrounding the Skype button.
How does it work?
The button performs various functions depending on what you’re doing with Skype at the time.
If you’re working on another app and feel the urge to Skype someone, pressing the Skype button, brings the software to the foreground. No big shock there.
When a Skype call comes in to you, pressing the button answers the call, bringing you live.
There’s a LED surrounding the button that shows various states of call as follows
- Orange colored when Skype application is connected to Internet and in idle mode
- Orange/Green alternate blinking when there is an incoming Skype call
- Green when there is an active Skype call in progress
- OFF when Skype application is not connected to Internet or not launched
The green LED between the mic and camera shows solid green to indicated you have a call in progress, perhaps to save you from the embarrassment of slagging off the person you’ve just completed a call with, while thinking the call had finished.
Calling quality
One of the concerns we’d had was the placement of the mic and the call quality that might bring.
We know that the mic on the Apple iBook lid is less than great to be using with Skype. We often find ourselves craning our necks forward, and half closing the lid to get close enough to the mic to make ourselves heard by the other party.
Packard-Bell appear to have got over this. In the call that we placed, the other end reported they could hear us perfectly well, despite us being around two feet away from the laptop and the room that we were calling from being pretty noisy.
On reflection we realised that the palaver we go through with the Mac wouldn’t work on this machine as, if you were on a video call, they’d be getting a view of your space bar.
Video built-in
As I’m sure you know, video conferencing has been included in Skype for a while now (it was one of the most requested features). By including the camera at the lid, Packard-Bell have made it easy to video call while on the move – without having to lash video cameras to the lid of your machine.
Having seen the preview window, we can report that the results were pretty impressive. The quality appeared to be more that sufficient for video conferencing.
General spec and availability
The general spec of this machine is described by Packard-Bell as having a “high-performance Intel Dual-core.”
We’ve absolutely no idea what the general computing function of this machine is – that’s not what we were looking at. Given that PC designs has been perfecting since the release of the IBM XT, we’d suspect that it’s pretty much as you’d expect.
The Packard-Bell EasyNote ‘Skype Edition’ is expected to be getting to retail in August this year at a cost of E899.
