About SIP Addresses
SIP addresses are used to identify users within a network just like you would use a phone number or an email address to contact a
friend or colleague. One of the major differences between phone calls, emails, and SIP calls is that they use different protocols to
start and end conversations.
Like email addresses, SIP addresses are a type of uniform resource identier (URI) that includes two user-specic parts, a user ID or
extension and a domain or IP address. Together with a prex and the @ symbol, they make up a unique address. For example, if
Caesar of ancient Rome had both an email address and a SIP address, they would be mailto:caesar@ancientrome.it and
sip:caesar@ancientrome.it respectively. For more examples and descriptions, see below.
SIP addresses are also known as SIP URIs or, in some cases, SIP numbers. For more information, see the PBX’s and service provider’s
instructions.
Example
sip:3468@172.25.33.142
sip:3468@voipprovider.com
