I'm a big fan of Asterisk on router -- imho, it's the perfect platform for anyone want to try Asterisk at home -- 24x7, fanless and even the cheapest router can handle at least 2-3 concurrent conversation. Before this WZR-HP-G300NH, I had Asterisk running on a WRT54G-TM for over a year with lots of fun.
Installing Asterisk on the router is easier now as current OpenWrt trunk build(the one we use) includes prebuilt Asterisk binaries. As always, since OpenWrt is designed to work with / not /opt, some adjustment is required to get Asterisk working properly.
