It's not necessarily easy, since SIP proxies do not, by their very 
nature, lend themselves to this sort of thing, but rtpproxy does have a 
timeout signaling socket:

But honestly, you'd be better off with a purely SIP-based method of dead 
peer detection, be it making the endpoints use SIP Session Timers, or 
using the Kamailio dialog module's OPTIONS-pinging method:
