So Christmas is upon us and another year has rushed by. What's new for the New Year?
Well hopefully some more updates to the Blog. My PIKA Warp needs an update and the GSM cards are out so need to get a play in the lab with those.
Some new exciting products with Virtus-IT on the horizon, and Cloud Computing VoIP QoE solution to work on.
My Oracle CCA instance needs patching to 8.1.3 FP2, there a new cool Dialer functionality built in from the guys using the Sangoma/Paraxip Netborder Call Analyser, can't wait to get that working. I've got the trial version of the dialer downloaded from the helpful guys at Sangoma - thank Doug V! I've also been have a little tinker with the CTI integration using some PHP scripting to grab the Parameters passed by CCA in a screen Pop -works just sweet - now to have a play with the Webservice API - wow-er not so sweet!
Happy Holidays!

HD Voice taking off
I read this piece on VON with interest about Voxbone transcoding from G.722 to Sype's Silk codec, since a lot of IP phones are now shipping with G.722 codecs looks like we finally get to share in the HD voice revolution...
May be we'll start getting disappointed with GSM voice quality, it will be interesting to see as IMS networks are finally delivered over the next year or so with IP-Centrex service, if we'll see complaints for mobile call voice quality as people can more easily slide between their fixed office phones and mobile devices. Or will we see HD codecs creep into the mobile space as LTE kicks in. Who's gonna be the early carrier to adopt VoIP over HSPA QoS and wideband codecs, or are we gonna have to wait?
Or wait - "Hold the Phone" - Haven't we got VoIP enabled devices already with WiFi and yes - applications like Fring (I have to use fring 'cos my mobile operator broke the SIP stack on my Nokia 5800! - But actually Fring is pretty cool too! ;o)). Pitty Fring doesn't have HD voice codec yet.

Happy 40th Birthday - Internet
It can't have escaped everyone attention that the Internet is 40 years old. The little video history is on National Geographic News.
An this one.
Well it nearly passed me by!
Time for a visit to the Computer Museum in Manchester.

IAX2 and PIKA Warp/FreePBX
Right now we're cooking - FreePBX configured with my IAX2 trunk to the TalkOn Network and we've got the PBX up and running. Analogue phone on my desk and a couple of other test phone (Aastra, Snom and Grandstream) all hooked up.
Final test - will it pass the "Wife test". I have found my wife to the perfect tester (and to be fair to her long suffering from my constant tinkering with the phones in the house!) Time to Hook the Warp up to my DECT/IP handsets (Siemens Gigaset S450) on there too, and see if she notices the join....
Watch this space either for the usual beating (you've been messing with the phones again!) Or maybe I'll get away with it this time?

FreePBX on PIKA
Not being very familiar with the Asterisk GUI, I decided to Flash my PIKA Warp with the latest FreePBX build.
Wow! That was easy, I download the pre-built image files from the Warp Xtra site. copied them over to my SD card (as the original compress file), popped the SD card in my Warp, logged in over SSH, unzipped the file, popped the files in the root of the SD card and rebooted....
A second reboot later and FreePBX loaded.
Login over SSH again, amportal stop, pikacf to set the cards to UK/GB setting, reboot and hey presto. Warp with FreePBX.
Then using the FreePBX GUI grab all those modules from module admin. Plug in my trust £9.99 analogue phone in the inbuild FXS port. Quick config in GUI for a Queue with music. Dial the Queue number from my analogue phone and Yeah! Music.....

PIKA day
Tuesday June 23rd was a chance to meet and mix with the PIKA guys for a day overview of the PIKA appliance and some tech discussions in the afternoon.
A great day with the opportunity to catch up with some new people and meet face to face some people I only know from phone conversations.
Thanks to the guys at PIKA (Maarten, Terry, Alain, Mark)....

Back to the lab PIKA vs. Intel Atom vs Grandstream GXE5024
In this entry I try to draw some comparisons between the PIKA, a home brew Atom and Grandstreams offering.
Overall Price for similar ports.
OK so back to playing with the PIKA and my latest edition an: Intel Atom Dual Core (330) Mini ITX machine. This is a small form factor Mini-ITX board in flat case, room enough for the 160G HDD and 1G RAM, but not enough room for expansion cards - even though the motherboard has slots. That said, this system is an absolute steal @ £189 ex VAT, combined with a Grandstream GXW-4104 or 4004 FXO/FXS gateway @ & £157 & £100.60 + VAT respectively = £289.50 for 4 ports FXS or £346 for 4 FXO.
This now sits next to the PIKA system for a side by side comparison. Initial price comparison looks good PIKA comes in @£385 ex VAT + £82.50 for FXO or FXS or ISDN2e cards = £467.50 for 4 ports.
Both the PIKA and the Atom + Grandstream, offer powerfail safe for the POTS ports, so on the surface the Atom wins on price.
The other offering in this space is Grandstreams GXE5024, coming it at £393.60 for 4xFXO ports. Alas I haven't got one of these to play with but on the surface it seems to offer similar specs to the PIKA and home brew atom.
Warranty and guarentee periods on most electronic of this type come in around 1 year or 2 years so you can expect them to last at least that long.
Both are quiet for use in a desktop office environment and the PIKA can be hung on the wall. For Sheer simplicity in set-up for the end user, the PIKA LCD panel helps to see what's happening in the system and getting access to the IP address of the box is simple by passing your finger over the display it swaps to display the units IP address.
So for system resellers with technical expertise, the roll your own can just about work out on price. For end users there's a hidden problem with the Atom system, the onboard Gig Network card is a Realtek that requires drivers from the Realtek website to run under Centos, the OS inbuilt realtek driver doesn't work. So my trusty Speedtouch USB 10/100 NIC from Thomson works out for getting the driver installed.
So how much power do the PIKA and Atom systems take?
I've been sitting watching my power meter and I can see a fairly consistent 62W out of the Atom system with no calls on the system, that's a little higher than I would have thought since the Atom CPU is claimed to consume only 8W. Then I turned off the LCD monitor! That's more like it - 36W.
Now the PIKA - WOW - that's more like it! Just a nudge under 7W, with no calls in the system.
Summary
for the sub £500 PBX offerings you've got some options. The PIKA is easy to set-up, very power efficient and comes with a variety of interfaces.
Home Brew saves you a few quid, but creates the pain of having to compile you're own ethernet drivers.
The Grandstream offering looks favourable too and even claims video support. But where it would fall down is on the list of features from numbers of conference rooms, IVR, ACD features and desktop CTI integration. Since the PIKA and Atom home brew can use Trixbox, you can add HUDlite and desktop screen pop for outlook contacts.
