OPTIONS: Communicates info about the calling/receiving SIP phones’ capabilities. There are 14 SIP requests total, but the first 6 are those you’ll see pop up in call flow diagrams most often. It’s how the devices communicate behind the scenes to establish the connection or alternately let you know that a connection can’t happen at that time (e.g., the call goes to voicemail or transfers to another endpoint). When one SIP device sends a request to another, that endpoint sends back a response. When making a SIP call, your SIP device sends requests to the endpoint (the other SIP device). “SIP call flow” is a fancy term to describe how a SIP call works.
