I have also posted this in the installers thread -

I would like to ask a question that may seem stupid to most of you but here goes.... I am bidding on a wiring job in which all the wiring in the premise will be upgraded to Cat5e so they can swap out their existing Nortel MICS to a Cisco VOIP system. I don't know what model of Cisco phones, but my contact said they had a data port on them in which their PC's would be connected. How much bandwidth will the Cisco phone rob from the PC? Obviously, since the phone and the PC are sharing the same cable, the PC will not have the same bandwidth it would have if it has its own Cat5e drop.
Having read so much negative stuff about Cicso VOIP, I feel like I need to run two Cat5e to each station.

Thanks for any input,
Bill
