keeping callid is legal and desirable for REGISTER

with 0 means unREGISTER, no clue why k-phone sends it...
when kphone is registered with the proxy and the user presses unregister
button, kphone sends register message with expire=0. that causes
unregister button to turn into register button. when the user then
presses register button, kphone sends a register message with
expire=configured value.
i dont see any problem with that behavior.
