I'm the part time computer guy for Montessori In Redlands, and they've asked me to help upgrade their phone system.

They currently have a Panasonic DBS VB-43050 and they have Active Voice Repartee software running under OS/2.

They were quoted a Nortel system that's about twice as much as they have budgeted, so we're looking at upgrading the software to a Windows version and perhaps finding some more modern compatible phones.

My questions are

1) is it possible to get just the software upgraded? Active Voice referred me to their dealer list which is out of date (disconnected phone#s) and the dealers I talked to don't sell software separately.

2) are there compatible phones out there or are we stuck with the older Panasonic phones (VB-42210B and a single VB-43233B).

3) where's a good place to learn more about this stuff? i.e. phone systems in general, terminology, etc.
