    Voice Over IP

    Anybody done a VOIP service in house? As in just order the BT ISDN30e line, get a DDI range, install and setup an astrix box and put in the phones?

    If you have, was it easy, and how much did BT charge for the ISDN30e line?

    We got a ISDN30 with daisy communcations. They installed it for free.

    Would that be daisyplc.com ?

    How many lines did you take out, and how much do you pay in line rental? Seems a bargin free install!

    I did the asterisk box and phones bit, but not ISDN though... We only have 3 lines, so there's not really a need as yet for ISDN.

    The asterisk part involved a lot of research and testing to get it how we wanted it. We spent 6 months on the project.

    I did an office install with Asterisk and six extensions, including full cabling, in two days a few weeks ago. Route all calls over an internet gateway, so no expensive interface hardware.

    And you've had zero complaints from any of the users? As in, every function is perfect straight away? How did you find out the actual requirements of the system in 2 days?

    Yeah daisyplc it is. We have 8 lines which seems to suit us at the moment.
    I'm not sure what the line rental is.

    Pretty much. The only things I've tweaked since are not requiring 9 to grab a line, and making day/night mode automatic on a timer.

    I should clarify, though, that three of us spent a day cabling and then I spent a day installing and configuring. Requirements and planning I did before hand, about the equivalent of a working day I should think. It's a replacement for their old proprietary system, so they had some frame of reference for deciding their requirements, which helped, and then chose features to add on top.

    There's nothing very complex; six extensions, voicemail, busy lamps, hunt groups with fallover, automatic handset configuration and external access, so it wan't a huge project. On a school project I'd build a small system in isolation for key people, and then roll out to the rest of the building over the course of a few days.

    If you want something even more easier use this - Asterisk at Home or Asterisk at Work in 30 MINUTES :: AsteriskNOW |

    I set up an asterisk box at home a couple of years back using a vmware player appliance. I really just wanted to have a play with it, but didn't have any concrete plans to implement it in the near future.

    I'd be interested to know a few things from those that are using asterisk in schools so that I'm better informed if the school does want to change from our now unsupported old-style digital PBX to voip goodness...

    How much space is required for a reasonable amount of voicemail/user?
    Do users have access to any of the web interfaces for configuring their number?
    Do your users have access to their voicemail from outside the school?
    If yes, can they also access it out of hours?
    Is there a password policy for protecting voicemail boxes?
    How separate is the voice network? i.e. Did you just set up QoS? or give it its own VLAN? its own switches?? its own trunk datacabling???

    Sorry for asking so many noob questions, but it's a little outside my normal field!

    This is the office install, don't use it in school yet, so some is hypothetical and some is experience.

    I've found that an average message (30 seconds or so) is taking about 20Kb of space in gsm format. Of course, your mileage will vary. I'd allow a couple of Mb per user to start off with.

    They don't, but could have. There's nothing they need to get to though. Things like do not disturb, directory etc are all done by Asterisk.

    Yes, if you call from a nominated line and have a PIN, you can become part of the internal exchange (and therefore reach any of the features that they can normally).

    Optionally.

    Not in this case, but if I did it on a larger scale I'd be inclined to use QoS, and perhaps a VLAN to stop, but with the Aastra phones I used I can push an admin password out from the server, so casual fiddling isn't a problem.

    If you're anywhere near and want to see it in action, I'll arrange for you to go in and have a look, they're very friendly.

    A couple of meg per user is usually plenty.

    No. There is no need at our school.

    Not at our school. It could be enabled if we wanted it though.

    Voicemail passwords are actually a PIN, so it is rather difficult to enforce such a thing on a number that is phone readable.

    Seperate VLAN with QoS enabled. Doing it seperately defeats the point of converging your IP network with your phone system.
