SIP (Session Initiation Protocol) is a communications protocol for signalling and controlling multimedia comms sessions, and is a commonly used VoIP protocol,
SPAN (Switched Port ANalyser), is sometimes called Port Mirroring, and is a mechanism used within Ethernet switches to select specific network traffic and send a copy for analyse to a device on a specific port. For call recording this would be used to capture the actual voice content component of the call.
