Explanation

SIP uses two primary URI schemes: 'sip:' and 'tel:'. Option B ('sip: [email protected]:5060;user=phone') is a valid SIP URI - it uses the 'sip:' scheme, includes a user portion, a host/IP with port, and the optional 'user=phone' parameter indicating the user part is a telephone number. Option E ('tel:[email protected]') is a valid tel URI format used to represent telephone numbers within SIP. Option A uses the invalid 'phone:' scheme. Option C ('Usipbob.cisco.com') lacks a proper URI scheme delimiter. Option D ('[email protected]') is missing the required 'sip:' scheme prefix.
