CLCOR (350-801) Topic 2.1a: SIP Call Setup and Teardown

This video is a sample from our upcoming CLCOR (350-801) Video Training Series, which is being released February 2021.

In this training video, we'll consider SIP, which is short for Session Initiation Protocol. Specifically, SIP is a standards-based call signaling protocol that can be used to setup and teardown calls between a couple of Cisco IP Phones. We'll consider the messages exchanged during a SIP call setup, and we'll distinguish between SIP Early Offer and Delayed Offer.
