I've got a couple options. Option 1 - Just buy IP phones and use those. Have all of them talk to the SIP provider and be done with it.
Option 2 - Buy a VoIP appliance (there are lots of different ones) with enough analog jacks for your phones (or maybe a mix of analog and digital phones) and use their management gui (probably a local or remote web server) to configure the system. Option 3 - Roll your own Asterisk system or use Trixbox (which is easier than building Asterisk from scratch) and an analog card or two. I happen to have a Digium 8 port FXS card that we just took out of service, if you're interested.
