If you have a fairly decent 100Mbit switch, you'll be fine. I assume
you will make up to 10 simultaneous calls, so you can calculate the
bandwidth you'll be using.
(http://www.voip-info.org/wiki/view/Bandwidth+consumption) When using
the G.711 codec, it'll be about 1.5-2Mbps when doing 10 simultaneous
calls.

If you don't overload your internal network, you'll be fine..
