We are the champions :)

We are the champions. Yay. Last night Timico together with VoIP infrastructure partners Genband triumphed winning the Global Telecoms Business Award for Innovation. In the telecoms world this doesn’t come any better. Folk had flown in from all over the world although because everyone was in a penguin suit the only way you could tell was from their faces. Had everyone been wearing national costume it would have been interesting:)

The event took place at the Park Lane Hotel. If you’ve never been it’s worth a visit. Terrific venue, especially when you win. Champagne corks popped and a wonderful time was had by all.

Our award was for our Unified Communications Solution / mobility for business. This is our SIP service with Android and iPhone clients. If you haven’t tried it it is definitely worth a go. More details here.

The only downside to last night was that they didn’t give you time to do a speech. However because I can write what I like on this blog I thought I’d do it here instead:

It is a great honour to receive this Award on behalf of Timico in front of such a large and distinguished audience. I’m not going to say much but there are a few thank yous I do need to make. First of all thanks to all the staff at Timico. Couldn’t have done it without you and I’m just sorry that it isn’t practical  for everyone to be here up on the stage and to drink Genband’s champagne in this lovely art deco ballroom.

Then of course there are Genband themselves whose technology has made it all possible and who are great supporters of the trefor.net Xmas bash every year (12th Dec 2013 – make a note in your diaries now). I’m really pleased to be here with David Hiscock the Genband VP for EMEA who is a very good guy.

Next up are mum and dad and my Aunty Mair who has been in hospital but is hopefully now on the full road to recovery. Thanks mum and dad for everything you have done for me. Looking for ward to seeing you in the summer.

I also promised the kids I’d give them a mention so hello to Tom, Hannah, Joe and John. Don’t stay up too late now and make sure you do your homework.

And finally I can’t come up on this stage without saving the biggest thank you of all to my wife Anne who has had to put up with me for 25 years come this August. This trophy is for you although I’m sorry we can’t keep it on the mantelpiece because it will have to go with all the other silverware in the display cabinet in reception in Newark.

None of it is really silver but I’m sure you know what I mean. It’s all high quality crystalware or perspex or some similar material that looks very nice when lit up on display. It is getting quite crammed mind but hey. We don’t want to stop winning awards do we?

I think that’s it. I’ve covered everyone. Oh no and thanks to Global Telecoms Business for being such a great publication and for putting on this wonderful evening. This award makes all the hard work and effort worthwhile.

So thanks again and hope to see you all next year.”

There we go. That would have been my speech. Short and sweet eh? The photo below is of me (on the right) with David Hiscock (left) was taken by Debbie Rowe of Global Telecoms Business. If you click on it you get another photo showing Debbie herself taking the photo of me and Dave.

Timico cha cha cha.

S3 SBC, rhymes with VoIP, Securitee – Session Border Controller @Genband @Timico

Trefor DaviesYesterday I wrote about our new mobile VoIP App for the iPhone. This included a link to a press release issued by Genband, our VoIP infrastructure partner.

That release covered more than just the mobile VoIP iPhone App. It is a bit of an overall solution release but an important bit covers our acquisition of the Genband S3 Session Border Controller.

The SBC has been a bit of a controversial beast in the world of purist VoIP engineering. It’s purpose is to manage VoIP sessions across different networks. In its earliest incarnation it was used to convert VoIP signalling from the old H323 video conferencing protocol (also used for just voice in older VoIP services) to the more modern and up and coming SIP (Session Initiation Protocol) or perhaps to a variant of MGCP (Media Gateway Control Protocol). As a “border controller” it also grew in functionality as a device used to manage the security of a network.

The conceptual problem of the SBC amongst the early VoIP pioneers was that it operated as a “back to back user agent”. In other words it effectively terminated a signalling stream on input  and started it up again on output. This meant that in the “open internet” it would not necessarily be possible to trace a VoIP signalling packet from end to end as you might be able to do with other non-voice packets using tools such as tracert, the outcome being that it would be harder to debug problematic services.

This was at a time when the theory stated that all VoIP calls would be free heralding the end of the telco and paid phone calls as we know it. This Utopian scenario was underwritten by companies such as Skype who appeared to offer free phone calls to all. Of course to be confirmed and adopted by the general scientific base, theories need proving in practice and even the virulently successful Skype ended up demonstrating that it has to pay for its infrastructure somehow by starting to charge for some of its services.

The growth of the VoIP market1 has also stimulated the growth of a VoIP security sector. There was initially an element of playing on the fears of people entering uncharted technical territories. The fact that VoIP is designed to operate on the DNS based internet2 and functions in a similar way to email and web browsing opens up opportunities for fraudulent activity in the same way that we have become accustomed to such happenings in our general web use. Email SPAM is replaced with VoIP SPIT (computer generated SPAM for Internet Telephony bombarding the world with automated sales messages).  The use of a crawler ploughing through blocks of IP addresses looking for open networks to penetrate is replaced with a search for exposed network based iPBXs that can be exploited for financial gain.

There are many precautions that can be taken to remove vulnerabilities from a VoIP network but if you are serious at security you will want to use a Session Border controller.

A VoIP network, at least if it is to be usable by business, needs managing to maintain its quality and reliability and the SBC plays an integral role in this. The SBC today, far from being the object of criticism of the VoIP network engineer, is the demesne of the grown up Internet Telephony Service Provider. Think of it as a super security tool that secures your network and cements the quality of the service it supports.

Looking at it parochially I’ve been wanting an SBC “to play with” for years, ever since we started our hosted VoIP service. We put a lot of effort into the management of security of our VoIP users but the Genband S3 SBC, covered in the press release, allows us to take this to new heights.

The Genband S3 effectively acts as a VoIP firewall. It manages network access using real-time and aggregated admission control policies. It can, for example, spot and prevent the SPIT attacks referred to earlier.  It will also help Timico as a service provider to control the quality of the VoIP service with capabilities such as the automatic monitoring of network bandwidth rates and capacity.

From Timico’s perspective as a voice carrier the Genband S3 will allow us to hook up with many more interconnect partners because as a border controller it allows us to manage interoperability with different carrier’s kit. The SBC will also provide us with the flexibility to fine tune routes based on both cost effectiveness and quality. For example if a specific route begins to suffer from poor call completion rates the S3 will detect this and intelligently reroute traffic to that destination via a different interconnect partner. The S3 is also hugely compatible with our Genband A2 VoIP platform and will scale to 25,000 concurrent calls that effectively supports a subscriber base of over 250,000 users.

The S3 is relatively new to Genband. It came with the acquisition of NexTone, one of the market’s original and leading SBC vendors. This has brought with it a maturity and pedigree of user base that is not only reflected in its functionality but will quickly help Timico cement our position as one of the leading VoIP providers to the business market. Bit of marketing blurb there but it is actually based on solid engineering principles.

If anyone wants to chat more about our new S3 SBC drop me a line, call or hook up with me via @tref on Twitter.

Ciao.

1 note there will come a time when we don’t talk about it as a VoIP market. It won’t be long before we have to simply describe the world as a communications market which contains a subset known as the old fashioned telecommunications network as championed by the ITU (another story in itself).

2 It still doesn’t fully merge with the domain name system as this would rely on every ISP supporting VoIP on its DNS servers. The principle of domain based routing is still the same for VoIP as for regular web traffic.

What’s your Lync address?

Lync video call screenshot with Terry Bowers and Trefor DaviesThis good looking boy in the screenshot is Terry Bowers, Head of Professional Services at Timico Technology Group business Redwood Telecommunications. We are obviously engaged in serious conversation as neither of us is smiling.

The client itself is a feature of Microsoft’s Lync, something we decided to play with at Redwood following the UC Expo (UC = Unified Communications) trade show earlier this year. Redwood now have it installed at a number of their customers and it is regularly used in communications between these companies and also with suppliers.

We are using an all in one Lync box from Active Communications, This is a lovely appliance that removes the need to deploy the complexity of servers1 that has been Lync (note innovative & brand new collective noun). ACS have not only integrated Lync but have done it using virtualisation which means you can deploy it within your own virtual infrastructure. Also it scales very nicely.

I use a number of multimedia clients such as the one shown in the screenshot. There’s Timico’s own Genband based Outlook client, Google and Skype. All are used to talk to different communities and whilst there are some differences they typically all work well.

A few observations arise:

Sponsorship from BT Genband Timico and Thinkbroadband for trefor.net Christmas bash

I am happy to announce that BT, Genband, Timico and Thinkbroadband have stepped forward with sponsorship for first annual trefor.net Christmas tweetup.

The party starts at 1pm on Friday 17th December in the platform bar of the Betjeman Arms in St Pancras Station. Get there early to avoid the crush – thanks to our sponsors the bar will now be free until the money runs out.

The guests already signed up come from a wide range of communities of interest including internet engineering, VoIP equipment, Parliament, DEAct, rural broadband, ISPs ITSPs, regulatory specialists, embedded software developers, oil and IT industry executives,consultants and the media.

If you haven’t already done so please sign up here

Some people who have expressed an interest in coming but unable to make this one have asked when the next one is going to be?  The end of the IPv4 address pool or  “Apocalypse IPv4”  party is already in planning for the Feb/March timeframe. The date for this one is TBC pending the exhaustion of the IANA address pool and will be the subject of a further announcement.

Expressions of interest from potential sponsors for the Apocalypse IPv4 event are now being taken. This should be of interest to carriers, equipment vendors and anyone else in the IPv6 space.

GenBand set to rock and roll with Nortel acquisition

Next up in the guest stitched up to play the guitar in front of a totally uncritical audience is Jason Dackins of GenBand. Up until a few months ago I had never heard of Genband.  Now they are about to become one of my most important strategic partners as they acquire the Nortel carrier division, CVAS.

GenBand is being financed by One Equity Partners (JP Morgan) and is putting together what I believe will be a major force in the carrier VoIP market.  Other assets in the stable include the Session Border Controller NexTone. 

I was happy to entertain them and little did they know that they would be entertaining us.  Jason is playing Yviva Espana (I think).
