The first step will be to use Kamailio as an SBC and start the RTPProxy for each session terminated on this wholesaler. Is there a similar mechanism on RTPProxy sides that can detect this particular call-flow and hang up the call?
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:
