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.

Credit crunch bad news/good news

Friday, February 13th, 2009

One of our account managers told me in passing that a customer of his had just shut up shop. Bad news I thought. Is this going to be the way of it in 2009?

The good news though is that what they have actually done is closed the office and moved their 5 members of staff to work from home to conserve cash. Their VoIP subscriptions, which they were already using flexibly from both office and home, will just follow them.

Business is still there to be grasped when times are hard.

Heavy snow stops staff coming to work – business unaffected

Monday, February 2nd, 2009

The Timico car park is emptier than usual this morning as heavy overnight snow has prevented some  staff making it in. In fact most of the country seems to have ground to a halt. In London the buses aren’t running, some airports are closed and the train service is limited. We are just not used to snow in the UK and the official advice is not to travel.

Of course the newpapers have the usual dramatic headlines. “UK business loses £600m a day due to weather.”  The weather, I must say, has not made a blind bit of difference to Timico as most of our staff are already geared up for flexible working.

They can work from home just as easily as from the office (in some cases more effectively !!) because the business is fully IP enabled. Access to telephony (VoIP), intranet - CRM, billing and support platforms. In fact this infrastructure also makes it easy to offer a 24 x 7 round the clock support service.

It also means, and excuse me here I’m on a bit of a roll,  we have lower absence due to sickness and with a high number of female staff can be much more flexible in our approach to maternity leave.  So I don’t think the snow will have affected us at all.

My kids on the other hand are extremely disaffected. They had tuned in to the local radio station at the crack of dawn to listen out for school closure announcements. It seemed that practically every school in Lincolnshire was shut except for those of the Davies offspring!  Bummer.

Nortel Has Filed For Chapter 11 – Bankruptcy Protection

Wednesday, January 14th, 2009

The hot news this afternoon is that Nortel has filed for Chapter 11 bankruptcy protection in the USA. This, as I recall, gives them a year to restructure their business under protection of the US Government without having to “worry” about action from creditors. There were  noises on the airways for some weeks regarding the company taking advice over Chapter 11. It goes to show there is no smoke without fire.

Nortel’s asset levels of around $1Bn are dwarfed by their liabilities of $12Bn. With debt due for repayment in 2011 they will have found it difficult to reschedule this debt under current market conditions. I understand that $107M was due tomorrow.

Speaking to staff at Nortel the whole company is affected and an interim “committee” has been appointed as an adviser to the board.

The biggest problem the company was facing, aside from the repayment of debt, was the funding of R&D moving forward. In particular in the enterprise and carrier VoIP space. The Metro Ethernet business, where Nortel is market leader but which is no longer core to their future VoIP plans, has been for sale for some time in order to provide working capital to fund R&D. I understand that some (unspecified) bits have been sold but a further announcement regarding this will be due in a couple of days.

Life is never boring. Nortel expects to come out of Chapter 11 as a new debt free entity. The brand is strong and the company itself is one of the oldest in the telephony business, if not the oldest. I can’t see it disappearing.

Bloomberg’s comment on the news is here.
