SIP allows an identifier for a person, which can take the form of a phone
number, to be mapped to many devices where a user may have connectivity,
including PC phones, wireless phones, home phones, etc.
You might also want to see enum (rfc2916), which explicitly is about a phone
number mapping to a set of URIs that identify the user.
