keeping callid is legal and desirable for REGISTER requests. 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.
