Processing!!---------------------------------------------------
Since Chang-Yu have finished his testing, I would like to have our domain "voip.edu.tw" to be "SIP-enabled". The goal in the first stage is to make our lab members SIP-reachable. That is, people can make a phone call to "solomon@voip.edu.tw", which will be sent to ms11 (I've created the DNS SRV entry _sip._udp.voip.edu.tw), and then ms11 will re-write the Request-URI to sip:20001@163.22.20.154. Hsiao-Ting is assigned to this task. I assume she already has the sudoer permission. Please also give her the MySQL root password so that she can investigate the on-going work of Chang-Yu and further enhance it.
