    What I mean is I am looking for a firm outside Ireland that can support Yeastar. As far as firewalls go I am happy for the Yeastar-supporting VOIP company to recommend something simple. There is very little web traffic on the VOIP link and I'm prepared to cut it out entirely if it makes thing simpler.

    We're running into some problems with our system and want to investigate different support companies (apart from B4B) to handle our Yeastar and firewall configuration. Likely this could be done remotely. I've drawn a blank on firms in Ireland who support Yeastar. Can anyone recommend a Yeastar-supporting phone company?

    Using Yeastar S100 PBX and Yeastar phones. Works well

    Thanks. I'll try these solutions separately

    I have removed nearly all the pics and iMovie clips, but the iPad says that iMovie is taking up 5 or 6GB. Pupils say that they cannot record clips as the iPad is full, but I have deleted nearly everything - everything that *I can see*. How do I see and kill all the hidden iMovie clip fragments to actually free up space? Or is the only solution to wipe the iPad totally and reinstall the apps?

    Our little webcam doesn't really hack it. I want to be able to zoom to anyone in a group of 20-30 pupils, in not very good light, as we have a projector on at the same time

    What is the best way to do this? I need to take all my user accounts and information from one to the other.

    Ok thanks for all this. My system is very simple (unfortunately not simple enough). I am using the built in facilities in Microsoft Windows Server 2008 for mirroring and backup/restore. In the end I jettisoned all my old disks and restored my boot drive and user drive onto two new Advanced Format (AF512e) disks using my Server 2008 install DVD and my portable backup disks. I think I will rely on backup disks and not bother mirroring

    I'm a bit nervous about restore, never having used it in earnest before. If I restore to a new disk, will the Server 2008 Backup utility restore not only the files and folders but the shares, security info etc. as well? At what point do I logically remove the failed/failing disks from the system?

    I have been having some problems (lots) with a pair of mirrored disks. These hold our user folders. I replaced one of the disks, and still have a few messages "at risk" etc. Is there an easy way I can copy off the information and user shares etc to another set of mirrored disks? (It is hard to get non-Advanced Format disks now, I would like to be able to set up on two new Advanced Format disks. The current mirror is of course a dynamic volume which doesn't make things any easier.

    Dear ZeroHour, I too am having this problem with my home printer, and I would be grateful for a link to the beta-software that fixes it. Diagram

    OK The sequence is this: On all the edge switches (EXCEPT the EDGE SWITCH currently connecting you to the core switch) , set the uplink ports to be tagged and include VLAN1 (the managment VLAN) and other VLANs which you want on the switch. Set all the ports on the core switch to tagged and include VLAN1 and other VLANS which will travel through the core switch. Finally, on the switch currently connecting you to the LAN, set the uplink port to be tagged and include VLAN1 and any other vlan you need. After you have done this you can communicate again with all the switches in the network. I don't understand ezzauk's comments: on 3COM equipment links between switches have to either tagged or untagged (and can't be both) so once you decide to use vlans then the management vlan has to be tagged where it passes from switch to switch. Traffic from switch to workstation is untagged

    I have half a dozen 4400 switches connected by optical fibre in a star formation to a central 4900 SX optical switch. For simplicity, lets just look at two 4400 switches connected to each other via the optical switch. To configure a VLAN on the remote 44000 switch, I guess the first thing to do is to set the fibre port on that switch to taggable. As soon as I do this I loose connection capability with the remote switch. Then I set the port on the optical switch that is on the other end of the fibre to taggable. The third thing to do is to set the port on the 4900 SX optical switch that connects to my local 4400 switch to taggable. This will probably cut access to the optical switch. Finally I set the fibre port on my local 4400 to taggable, and I can connect again to the 4900 SX optical switch and through it to the remote 4400 again. Does all this sound sensible?

    Has anyone setup VLANs on 3Com 4400 series switches (3C17203) or 4900 SX optical switches (3C17702)? What is the precise order of instructions to create VLANs and assign them to ports? Do you start at the far end of the network and work back, or start in the centre and work out? All my attempts seem to add a VLAN2 seem to cut access on the admin VLAN1, and I have to reset the switch by logging on locally to it or by using the console port. Any help is appreciated.

    I've found that most Hitachi's have very similar throw characteristics. Of course, if you're replacing a lot of projectors maybe you want to go wide-screen Hitachi CPWX-410 has a long-life side-mounted filter and works OK in my clasrooms on eco-mode (not as bright, but extended bulb life)

    I had a similar problem, in the end I just lived with it and put the UFR II driver on workstations and printed to an IP Port. The copier account print-outs add one count each for A4 and A3 so you need other softwares to do the accounting properly.

    Pip99, Thanks for all this information. Currently I'm trying out some of these suggestions with DVB-T, not HD If anyone is following this path, I recommend using VLC Windows version. This is because some of the DVB-T dongles have an optional pre-amp, which Windows drivers can turn on. Symptoms of not having this on are: can't tune in to any multiplexes, or receive channels from high-powered multiplex only. Also beware that school RF distribution systems can filter out everything but specific analog channels, and then selectively boost the filtered signal. Obviously these will all have to be re-jigged before analog switch-off. I'm not sure if transcoding is necessary, but it sure helps if you install VLC on client computers to receive the stream

    The Grand National was live-streamed by iPlayer in standard definition only, so I wouldn't count on the World Cup in HD by this method I wonder do new-build hotels still have an RF distribution system or do they pipe TV, telephone and pay-per-view through a IP infrastructure?

    iplayer might be a way to go. I'm not sure if that stream is easily cacheable - there is technology in the live stream to prevent it being recorded, and in the stored-programme streams to stop them being shown after a certain length from the original broadcast. (see Wikipedia) If it isn't cacheable then that limits the number of stations that can simultaneously use it as they're all sucking up bandwidth on my Internet link. I think BBC and ITC split coverage of the World Cup.

    I don't know much about the law either. Can you give me a reference to the legislation? Note: I just want to stream live video from an unencrypted channel. I don't want to record anything or break any encryption codes, or stream it outside our premises. Morally I would not doing much different from buying a lot of these Peak DVB-T Digital TV (203244AGPK) Single Tuner USB stick | Peak | 203244AGPK. But of course the law doesn't always reflect morals.

    I confess I know very little about multicasting. But I just want the stream generally available so teachers and pupils can watch in any of their normally timetable rooms. I don't think there will be a lot of serious school work done when our internal exams are finished, and I am assuming that multicast will put less load on the network than a lot of separate streams to each PC. I was thinking of using either VLC to stream, or DVBLogic - provider of digital streaming connectivity solutions , in conjunction with a suitable input card or device. VLC compatibe devices are at Hardware Compatibility list - VideoLAN Wiki and I am sure there are some more devices which will work as well. Slingbox is no good From Slingbox FAQ: How many computers can the SlingPlayer software be installed on? Presently, the SlingPlayer software can be installed on an unlimited number of computing devices. However, a Slingbox can only stream content to one device at any given time. The software for a PC or a Mac is free. However, Sling Media charges a one-time fee of £19.99 for each device license of the SlingPlayer Mobile software.

    OK I know this box works for standard definition: SiliconDust HD Homerun dual DVB-T Network Tuner (from onevideo.co.uk) ** Is it possible to rig up something similar that takes a Freesat high-def signal and multicasts it? I'm only interested in the World Cup - multiple channel streaming not necessary. ** a review by Wayne Harrison at onevideo.co.uk states the following: ..............................Although this version does not 'officially' support multicast streaming (and this is reiterated on IRC) it will actually stream over a multicast port BUT (and this ISNT a fault with the unit) make sure your network switches support multicast streams as I found out that the streams will disconnect after an hour or so.

    Errrr.... In other words, just like the police system. How else would the cops match fingerprints? To be sure, the police keep an image of the fingerprint but that's only used for checking by humans after their system has sorted through their database and pulled out the most likely matches. Even though the PNC and your dinner card system store the information in an incompatible manner (and even that is debatable) the police could take a fingerprint they have taken from a crime scene (somehow connected to your pupils), wrap it onto a synthetic finger, put in *your* fingerprint reader, and watch it spit out the name of suspect#1.

    Ok, correction: you only have to spend E500 per month with Voxbone... I've tried Voipfone and drew a blank. There are all kinds of 'gotcha' add-ons in VOIP that I wasn't aware of (so..... just like computers then) For example, TerraSip calls are only free to other TerraSip users. And you can't get any UK number for incoming calls without paying for the number. Voipfone offers great rates for European virtual numbers - but there's an incoming charge per minute for calls made to you through these numbers. I'm thinking now that I should tackle this from the other end, and sign up with a HK or Sydney VOIP provider (ITSP), that way I could avail of any offers that included a bundle of outbound calls.
