it would be interesting to know just how much is spent on calls within an LEA or to other schools. If there aren't many calls made then there may not be much in the way of savings potential. By definition, the numbers called are going to be local so there may not be huge costs.
Janet has a project going to look at how VoIP can be used over the academic network to link universities etc - some of what comes out of this may be appropriate for schools and LEAs
I suspect a big problem will be getting it all configured. Most companies that set up a VoIP system won't be terribly interested in adding this sort of functionality - essentially, you're going to have to have some sort of routing which works out that numbers in a particular range (or in a table) don't go out through the normal ISDN line but go out to the WAN. There then has to be something which makes a connection (SIP??) to the appropriate switch for each of the parties you're going to call.
None of this is impossible; I think you probably have enough skill to set it up for yourself but that doesn't make it easy for us mere mortals :-)
What may be cheaper to do is to negotiate with the phone company for preferential rates for school to school calls. Depending on the size of the LEA and the bargaining skills of the purchasing people it should be possible to get pretty good rates (eg we have a mobile deal which I think gives us free calls between mobiles on the contract)
Norfolk LEA have moved over to voip for their internal systems I think and I keep meaning to have a chat with them about being able to call them via the county wide wan or to do inter school just like we can with vc maybe I will do that after half term.
Is there a right up of your asterisk system anywhere?
Hmm, worrying isn't it.
Do they also refer to the PC as the hard drive?
I know a few who refer to the PC being the hard drive, but we all know the hard drive is just the non-volatile storage device inside the case
Cisco is a bit strange - very proprietory in it's implementation.
We have 40 or so extensions in our school, so £10k wouldn't have cut it for us - using asterisk (with 2 hotswap spares of every component in stock) it cost us just over £6k for that.
I just can't see the advantage of a closed, proprietory phone systems such as cisco - it is just so restrictive. With asterisk, I can code my own fun and funky programs to do whatever I want. With cisco, i'd have to pay a fortune to do it.
In Nottinghamshire the LA is suggesting new schools install a Cisco Callmanager Express around £10k for 12 phones+server, and then one day the LA will buy Callmanager, and link them all together.
They pay someone from BTInet to set all the command line bits up, then give you training on using the web GUI where you can add phones, extensions, directory entries, hunt groups, voicemail boxes.
In theory it supports SIP, never got it working.
It's something we're looking into at our school. Although saying that we're keeping it local. I think the biggest fear (from a schools point of view prehaps?) is that telephone systems have almost always been outsourced. I know the biggest fear with our school about Asterisk is that it'll be mostly in-house support (while they dont have a problem with that, it's the fact that if I or the other technician leave... they would be stuffed).
I think it is a good idea, the majority of schools over here are connected to the same network, so it would make sense to move to VOIP.

hey, if you don't like iPods so much you could always, you know, if you think about it - and really put the hours in..
..not use one
Was it Bananaman by any chance?
Spotted a big bright yellow thing in the sky on the weekend. It hurt to look at it.
It's gone now though.

An interesting rumour. I certainly wouldn't put it passed them SYNACK
Ah but have you heard the new rumors floating about, that Steve is looking to classify all music as uncool in 2010 banning it from iPods completly and replacing it with a selection of Apple branded 'motivational material' the effects are said to be so strong that you will 'leak' said material out to others around you uncontrollably. The material is also said to be that potent that earphones and even the new flake earphones will be unable to channel it sufficiently. Helpfully this new device will be implanted in the brain stem negating the need for headphones. This will also allow the device to leach un-needed energy from its hosts brain in order to provide the customer with uninterrupted access to Apples extensive library of 'persuasive content'.
Flamebait anyone??? I hear it's in season
and its still raining
Rain rain rain.
Hope everything goes well for you.
