When client connects to server over TCP/TLS and REGISTERs two things that can happen.

1. Client can disconnect the connection when the App is killed abruptly and the client did not get a chance to send unregiter.

2. CRLF KA did not arrive due to network failures in the middle. 

Is there a way to remove contact from usrloc table. 

This can spare server from trying to send message to a client who is no longer connected to the server. 

It would be ideal if this can be done automatically with a module param in tcp or registrar.

Any suggestion on how to tie TCP connection with usrloc?

Thanks
