I'm not sure I understand. When the UA re-registers, does it use the
same port in Via as before?
If the UA reboots ser should get a reset on the old tcp connection the
first time it tries to send soemthing to the UA and the connection
should close.

Could you send me a more detailed description? Like UA connects to ser
, UA sends some sip msgs, UA reboots ...
A packet dump would also help a lot.
