[SR-Users] Best practice/routing block for TCP connection errors to UAC?

Scenario: clients registered by TCP/TLS dropping off the network,
kamailio stil thinks the client is registered and relays the INTIVE.
The error occurs at the TCP layer so no failure route is called.
ERROR: <core> [core/tcp_main.c:2690]: tcpconn_1st_send(): connect
127.0.0.1:48338 failed (RST) Connection refused
ERROR: <core> [core/tcp_main.c:2700]: tcpconn_1st_send():
127.0.0.1:48338: connect & send for 0x7f5494e906c0 failed: Connection
ERROR: tm [../../core/forward.h:251]: msg_send_buffer(): tcp_send failed
WARNING: tm [t_fwd.c:1567]: t_send_branch(): sending request on branch 0 failed
ERROR: sl [sl_funcs.c:362]: sl_reply_error(): stateless error reply
used: I'm terribly sorry, server error occurred (1/SL)
I want to send the caller instead a graceful failure route type
message as if the callee is not registered (404/486/603/408 type) but
don't understand how to hook a routing block for TCP errors.
