Phone numbers are an anachronism from the days of electromechanical phone exchanges[1]. These days we can name things more sensibly, so you can call Bob at example.com by just entering [email protected] into your SIP client.
That SIP client (or a server it is connected to) will then look up the SRV record[2] for _sip._tcp.example.com, connect to the SIP server it specifies, and ask it to be put in touch with Bob.
