Address Type  | SIP URI: A SIP URI uses the format of an email  | 
(SIP) | address, typically containing a user name and a host  | 
  | name, sip:user@host. For example,  | 
  | sip:dan@polycom.com.  | 
  | TEL URL: "Tel" means that a voice call is opened.  | 
  | TEL URL may be used when the UA does not wish  | 
  | to specify the domain that should interpret a  | 
  | telephone number that has been input by the user.  | 
  | Rather, each domain through which the request  | 
  | passes would be given that opportunity. As an  | 
  | example, a user in an airport might log in and send  | 
  | requests through an outbound proxy in the airport. If  | 
  | they enter "411" (this is the phone number for local  | 
  | directory assistance in the United States), that  | 
  | needs to be interpreted and processed by the  | 
  | outbound proxy in the airport, not the user's home  | 
  | domain. In this case, tel:411 would be the right  | 
  | choice.  |
