What are SIP Endpoints?

September 18, 2011 Leave a comment Go to comments

The term SIP Endpoints refers to the architecture that is responsible for enabling advanced call processing and call management functions.

SIP clients typically use TCP or UDP on port numbers to connect to SIP servers and other SIP endpoints. These SIP endpoints are typically referred to as the user agent client and the user agent server. A SIP user agent client is typically tasked with sending SIP requests while the user agent server receives the requests and returns a SIP response. The user agent client and server only assume these roles for the duration of a SIP transaction.

According to industry experts, because of the widespread use of instant messaging, SIP endpoints have become commonplace. Instant messaging applications such as Microsoft MSN Messenger and Apple iChat are SIP clients that can be used to transport voice and video free of charge. As a result of the growing popularity of instant messaging, specific instant messaging protocols based on the SIP standard have been created, including Extensible Messaging and Presence Protocol (XMPP) and Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE). These two protocols allow presence information to be exchanged between SIP endpoints.

SIP is an industry that has quickly burgeoned, particularly because of the growing availability of open source PBXs and hosted service offerings. SIP phones allow businesses to route calls over the Internet, through VoIP, which guarantees them reduced hardware costs and increased savings on monthly bills. SIP phones are the “wave of the future,” according to many industry experts.

Many SIP leaders attempt to distinguish themselves in this competitive market place by making sure that their phones are certified by Digium’s Asterisk and BroadSoft’s Broadworks, in particular. Other SIP providers will ensure that their SIP phones boast: noise reduction technology; lower power consumption; HD Voice in all series models; and multi-year warranties.
