For example, the Gizmo5 proxy (proxy01.sipphone.com) has been heavily loaded with SIP packets in the past. Asterisk is used with many different proxies so it would make sense for Asterisk to have an actual keep-alive function. For purposes of keep-alive, there's no benefit to using OPTIONS or NOTIFY instead of empty packets.
