If you have one switch for the whole network, you're generally fine
without QoS. Switches these days can handle full bandwidth on all
ports at the same time.

Anyway, Asterisk is no different from other PBX's when it comes to
QoS. Should it turn out that you actually need it on the LAN, just be
sure you set the tos parameters in sip.conf to something that is
prioritized by the switch.
