A Domain Name Server (DNS) SRV record helps connecting to a SIP user in a similar way that an MX
record helps email delivery. When you send email to "[email protected]", the MX record for
example.com might tell the mail transfer agent to deliver email to a completely different machine, such
as "zaphod.foobar.com". Similarly, when you want to make a SIP phone call to [email protected],
the SRV record might tell your computer that it should connect to "galaxy.starsystem.tw" to do so.
Dialing by domain names lets a SIP user have a single public "SIP address" which can be redirected at
will to their current location. SRV records maintain stability and also opens up the possibility to use your
own domain, regardless of the domain of the SIP service you are using.
