I may have lost the point already, but Android phone notices without
much delay when its network connectivity is lost.  So does Kamailio SIP
proxy (no resoponse to TCP keepalives).  When that happens, Kamailio
automatically un-REGISTERs the SIP client.  And when Android phone
notices that network connection is re-established, baresip immediately
reconnects to SIP Proxy and re-REGISTERs its account.

I don't see how UDP would work any better in such a situation.
