i want to ask some questions about building a network with ip telephony.
What is the best network design (price is crucial, but all component will be from cisco - types of switches, routers, phones) to build IP phone network with minimal 100 IP phones and 100 end users PC.
What is the cheaper solution ? - ip phones, switches with PoE or without it?.
Is needed same software to run IP telephony in network or is it only recomended thing?
or same material where i can find answers to this questions (not www.cisco.com :) )?
