The SIP URI scheme is a Uniform Resource Identifier (URI) scheme for the Session Initiation Protocol (SIP) multimedia communications protocol. A SIP address is a URI that addresses a specific telephone extension on a voice over IP system. Such a number could be a private branch exchange or an E.164 telephone number dialled through a specific ...
The URI scheme used for SIP is sip and a typical SIP URI has the form sip:username@domainname or sip:username@hostport, where domainname requires DNS SRV records to locate the servers for SIP domain while hostport can be an IP address or a fully qualified domain name of the host and port.
The original Request-URI is no longer valid, the new address is given in the Contact header field, and the client should update any records of the original Request-URI with the new value. [1]: §21.3.2 302 Moved Temporarily The client should try at the address in the Contact field.
The URI can then be used for obtaining the Internet Protocol addresses for services such as the Session Initiation Protocol (SIP) VoIP telephony. In the DNS, NAPTR records are used for setting the subscriber call forwarding/termination preferences. Therefore, the whole system can 'translate' E.164 addresses to SIP addresses.
P-Profile-Key: [22] The key to be used to query the user database (HSS) for a profile corresponding to the destination SIP URI of a particular SIP request. It is transmitted among proxies to perform faster database queries: the first proxy finds the key and the others query the database by directly using the key.
A URI has a scheme that refers to a specification for assigning identifiers within that scheme. As such, the URI syntax is a federated and extensible naming system wherein each scheme's specification may further restrict the syntax and semantics of identifiers using that scheme. The URI generic syntax is a superset of the syntax of all URI schemes.
The service name E2U+sip is an ENUM string indicating that the record can be used in telephone number-to-SIP-URI queries. [4] The client applies the regular expression !^.*$!sip:customer-service@example.com! , which replaces its entire URI tel:+1-800-555-1234 with sip:customer-service@example.com .
URI schemes registered with the IANA, both provisional and fully approved, are listed in its registry for Uniform Resource Identifier (URI) Schemes. These include well known ones like: file - File URI scheme; ftp – File Transfer Protocol; http – Hypertext Transfer Protocol; https – Hypertext Transfer Protocol Secure
