I am starting to install cable into a new office area and I needed to know if the current state of VoIP technology would allow me to run a single CAT6 drop into each office and support Gigabit Ethernet at the desktop as well as the VoIP phone at the same time? I would like to prepare to implement VoIP in the future but need to keep the cost down. Any and all help is appreciated.
Certain Cisco IP phone models are available with a PC port onboard. Most models support up to 100M connection speeds, while the newer model 79xx G-GE series supports gigabit. If you are planning to deploy gig speeds to the desktop right away you may want to budget for the higher model, otherwise 100M is the max for 7940/60 and 7941/61 (the non GE models). Any of these would allow one network connection cable per phone/PC combination.
You can check here for more information on the phone models, and remember to consider switches that support gig over copper if that's your plan.
