cordless phones in classrooms
We have 6 new classrooms that will make use of the cat5 network for the phone system. A company has charged a large amount to supply rj45 to analogue phone adapters, as well as the phones themselves.
I can see the adaptors on ebay for very cheap, though not sure about master/secondary option?
Also, if I bought a cordless phone for each classroom from, say Argos, would they all interfere with each other? The classroom layout is 3 up 3 down.
Thanks in advance!

I don't understand why a company has charged you for rj45 to phone adapters as they cost virtually nothing, in fact most give them away. Cordless phones talk to their base units seperately, although you can make more than one handset talk to a base unit, they don't interfere with each other.

One thing to watch out for on the cordless phone front is interference with things such as wifi. I can see 6 phones making the spectrum rather noisy!

They're just ripping you off - sadly, quite a few companies (particularly in the area of telecoms do this; I should have kept the quote for a phone system which included charges of about £5 for each mains lead!)

Our telecoms provider told us the other day that the phones they now supply have cat 5 sockets on them anyway so if using your cabling infrastructure you don't need the converters.
You need to see wether the lines you are going to be pluggin into are analogue or digital as well.
