I need some infrastructure advice.
My wife is a teacher in a Special Needs school that is being expanded in size. As part of the rebuild the teachers are keen to implement an internal phone system so that the children can learn to use the phone. These are vulnerable kids so it has to be self contained with no external access. As always, money is tight so we’re looking for low cost solutions otherwise the project won’t get implemented. As there is a school lan with a PC in every classroom Asterisk/VOIP appears to be a potential solution. We could buy in a second hand server to host Fedora/Asterisk. My issue is in determining what telephone handset would be feasible. Standalone VOIP handsets are too expensive (from what I can see approx Â£200 in the UK). The ideal solution would be a USB VOIP phone that could plug in to the classroom PC. There are a lot out there (as low as Â£10 each) - but they all seem to announce their Skype computability and not much else. Can anyone offer any phone hardware advice? The important thing is to ensure that the phones have a handset and buttons for number dialling - ie a headset plus software only phone is unlikely to satisfy the requirement.
