48p 2950s go from $2500 to $4500 list.
cheapest 48p 10/100 3560 is $6500 list, but you are getting a more or less
wirespeed router built in.
is you want 10/100/1000 then you can get that as a 3560, but not a 2950

Agreed
but PoE can be cheaper than arranging all the extra power feeds for the
phones, and if you have a UPS in the wiring closet covering the switches and
associated Voip servers then the phones work during a mains outage - some
places that is important.

you can do QoS on 2950s (there are 2 levels of QoS, with the better version
limited to the EI, more expensive flavor of switch, and no upgrade path)

The implied network design from the VLAN structure is that all traffic
between users and servers will cross between VLANs - in turn that means you
need a fast router - and the only cheap fast IP routers are layer 3 switches
like the 3560s....

so the router only needs Ethernet interfaces.
However, the choice really depends on the required performance and you
havent given much info about that.

power over ethernet - anything else you would add as part of the VoIP / IP
telephony deployment.
