SIP

The Universal Signaling Protocol

In the meantime, the Session Initiation Protocol (SIP) has established itself as the most important signaling protocol both in the enterprise environment and in the provider network. One major advantage of SIP is that it can be easily extended: New formats are no problem, both synchronous and asynchronous data streams can be initiated, and the communications partners can have a peer-to-peer or client-server relationship. After attending this course, the students will be familiar with the benefits, special features, and application options of the SIP architecture in general and of SIP trunking in particular.
