ITSPA event just two weeks to go #VoIP #polycom #microsoft

Wednesday, June 30th, 2010

It’s only two weeks to the Internet Telephony Service Providers’ Association (ITSPA) Summer Forum due to take place on Tuesday 13th July at the Polycom offices, Old Broad Street, London.

These events, chaired by yours truly, have become “must attend” occasions for ITSPs in the UK. On this occasion we have a Keynote Speech from Microsoft, an update from BT Openreach on their NGN VoIP plans, a talk from Polycom and a panel discussion on “Wholesale “VoIP. There is also an update from Matt Townend from Illume on the “State of the Union” in the VoIP market.

The wholesale panel has representation from the leading wholesalers in this space: Gamma, Magrathea, BT IP Exchange and X-Connect.

If you want to come there are still some places left though these things usually sell out nearer to the day so you need to be quick. Email admin@itspa.org.uk for more info.

Sonus Networks SBCs and the South of France

Friday, June 18th, 2010

It either makes me feel old or says how long I’ve been in the VoIP business when I say that I first met the founder of Sonus Networks, Ruben Gruber at a Pulver.com Executive Retreat in the South of France in 1998. I don’t think they even had a product at that time.

Sonus was Ruben Gruber’s 13th startup. 11 of these companies either floated or were sold privately and the two that didn’t make it were absorbed into the parent. That was an impressive record.

#VoIP SNOM #SIP and the Football #WorldCup

Friday, June 18th, 2010

When I first started looking at SNOM phones, perhaps 9 years ago, they were not very impressive. The handset was easy to knock off its cradle and the voice was tinny.

The phone firmware was impressive and the fact that SNOM was a very early runner in the SIP market is to their great credit.  SNOM is an entrepreneurial business.

The fact that SNOM is still around is also hugely to their credit and their handsets have come on in dramatic leaps and bounds. The quality of the plastics has improved and their expertise in software still comes clearly to the fore.

Fixed Mobile Convergence needs a philosophical change amongst the mobile operator community

Wednesday, March 3rd, 2010

FMC is really the nirvana where all networks finally converge. We are already experiencing it with internet connectivity – I keep up to date with facebook, twitter (and, ahem, of course work and email) via the internet connection on my mobile phone. We use both WiFi and 3G/GPRS to do this and whilst service can be intermittent it does work and is reasonably ubiquitous.

Convergence of voice over fixed and mobile networks is really the final piece of the jigsaw. Since Timico started selling VoIP services around 5 years ago we have been looking at FMC solutions. These have all been based on WiFi for the mobile piece.

VoIP QoS monitoring stuff

Wednesday, January 27th, 2010

VoIP QoS should not be an issue if the network is managed correctly.  This means the LAN, the WAN link and the core network of the service provider.

If the WAN link is an ADSL then it can be susceptible to congestion at the exchange though in my experience this very rarely happens, even at times of extreme network usage such as the Olympics or last summer’s cricket. Problems here typically stem from underprovisioning of bandwidth.  An Internet Telephony Service Provider should also be operating an uncongested core network and a properly designed LAN should never give problems.

Problems do still occur but if you have the right tools these should be straightforward to detect and sort out.  One of the ways we manage our network is by using probes embedded at key point in the network.

The diagram below shows the output of one such probe earlier this morning.  We are looking at connection downtime, lost packets or packets arriving in the wrong order, jitter and latency or delay. It can be seen that latency is almost the only measurable effect.  All the other numbers are too low to count. Even the worst case latency figure seen here of around 46ms is not going to be noticed by the human ear and most of the calls are below 20ms.

This is a very useful tool for IT managers having to run multiple services over a multi-site Wide Area Network and allows them to spot problems before anyone notices and starts to complain.

Halo3, VoIP and the kids

Friday, January 22nd, 2010

My two youngest  kids are just playing Halo3 on the X-Box against two of their friends – also brothers. They are talking to the other kids through headsets – the younger lads in one team and the older siblings in another.  Using VoIP over the internet!

I understand there is some echo on the voice (by the tone of the conversation) but they are plotting strategy.

I’m just flabbergasted by this.  I know I knew this was doable but when you see it in action it is amazing.

Doesn’t stop their mum coming in and sending them upstairs to get into their pyjamas though.  Some things never change!

Weather what weather?

Thursday, January 7th, 2010

I love this weather.  I’m a big kid really. I want it to snow so much that I get stuck in the house and can’t make it into the office. This isn’t just me talking.  I bet that most people in the UK are saying it right now.  Some of them will be stuck at home and those poor unfortunates, like me, will actually have made it in and are busy making cups of tea, talking to customers, running the internet (delete as appropriate).

Staying at home of course doesn’t mean that the world of commerce has to grind to a halt. I was quite thrilled as I wandered around the Timico sales floor talking about colours (this is topical – if you don’t know I’m not telling you) when one of the team mentioned that they had had a customer cancel a visit on them but had replaced it with a Meet Me Now web conference session.  What’s more they had pretty much closed an MPLS network opportunity during the call.

2010 – memorable for the best winter in (some people’s) living memory and the expansion of the VoIP online web collaboration market.

PS if you call me you won’t know whether I am at home or in the office anyway - 16 x 7 x 330.  Stack those snowballs up ready!

Job vacancy for VoIP network operations engineer – please retweet

Thursday, November 5th, 2009

I’m looking for a VoIP network engineer to join our expanding VoIP team.  The job entails assisting with the running of our Nortel A2E SIP platform, the development of new services, interoperability testing with vendors and other service providers, 3rd line support and, I’m sure, a plethora of other interesting and challenging tasks as we think of them.

VoIP is an important string to the communications bow these days. Timico is a VoIP operator rather than a White Label service provider reselling soneone else’s proposition. We probably don’t lead with VoIP in a large percentage of deals but the ability to provide VoIP services is becoming an important part of winning corporate Wide Area Network business.

For example it is fairly typical for a company to outsource the management of a few hundred sites’ connectivity to us.  They will then take advantage of the fact that  they now have an MPLS network and run VoIP between sites and to all their homeworkers.

If you want to join a company that is going placesdrop me a line with your CV or take a look at the Timico website.

PS it is always a risk posting a job ad on the blog – I get inundated with calls and emails from recruitment organisations! It is the cheapest way to advertise though.  Please retweet :-)

VoIP strategy

Wednesday, August 26th, 2009

We were discussing VoIP strategy today.  Timico supplies a mix of hosted VoIP and in premises equipment based on what is best for the specific customer need. In looking at PBXs it occurred to me that there should be a standard platform that will run anyone’s PBX software just like it is in the PC world.

Then I realised that this is where the world has been for some time now and that platform is actually the PC. With the advent of SIP trunks replacing the need for analogue or ISDN line cards all you need is a PC running a PBX software application plugged into your network somewhere (or at one of our datacentres).

I’m sorry if this is stating the blooming obvious to most of you but the fact is it has crept up on us to the point that most PBXs are now really just PCs and the vendors are trying to exit the hardeware game.  No longer do you need the specialised modules that handle conversion of IP traffic to outmoded devices and services.

The vision that came with SIP when I first started working with the protocol almost ten years ago has finally come to fruition.  You can now buy an off the shelf piece of hardware (ie the PC), run a wide variety of PBXs on it – take your pick, the choice is yours – and choose from hundreds of different handset  types at all sorts of price points and feature sets.

The problem now is that actually at the moment this choice still introduces a level of complexity to the game that will take some time to go away.  It still doesn’t make sense for a service provider such as Timico to offer a huge range of PBXs and handsets to our business customers.

When they go wrong, and this they are certainly going to do, you out there running your businesses and concentrating on what you do best need us to come and fix the problem. Or at least to send a replacement PDQ so that you can get on with life.  Nobody can do this if they have a hundred telephone handsets in their product range.

I’ll keep you posted on my exploration through different handsets and solutions. It is where I started in this game  and is a fun part of the job.

Ideal mobile VoIP client runs on a Blackberry

Friday, May 22nd, 2009
  1. Runs on a Blackberry. In my experience Microsoft push email isn’t reliable enough and I am seriously thinking of changing back to RIM
  2. Can call using any available network - wifi, GSM or 3G – deally can detect least cost route or allow you to set preferred network connection
  3. Has the same inbound number as my work desktop phone so I can seamlessly take the same calls wherever I am – this realistically has to be a fixed line number as you have to be a mobile operator to do it otherwise.
  4. Detects the presence status of my friends and allows me to send Instant Messages to any network.
  5. Active directory lookup for corporate users to avoid having to store all the numbers locally.
  6. High definition voice codec available for use on wide bandwidth connections (ie wifi)
  7. High quality speakerphone.
  8. Multiple VoIP subscriptions so that I can have both work and personal services on the same device.
  9. Front and back facing video (I’m not sure whether I’m kidding myself here!)
  10. All the usual touchscreen/music/GPS/integration with Twitter/Facebook and other social networking websites gadgetty stuff.
  11. Unlimited battery life (hey – I did say ideal mobile VoIP client :-) )

If anyone wants to add to this list feel free to drop me a line or leave a comment.
