Why each option
Desktop control mode in Cisco Jabber uses CTIQBE signaling over the CTI Manager service to allow a softclient to remotely control a physical desk phone.
CTIQBE (CTI Quick Buffer Encoding) is the Cisco proprietary protocol used by the CTI Manager service in CUCM to allow applications such as Jabber to send call control commands - answer, hold, transfer - to a registered desk phone in deskphone control mode.
SIP is a call signaling protocol used for session setup between endpoints, not for CTI-based application control of a desk phone.
XMPP is the protocol used for instant messaging and presence federation, not for controlling telephony devices.
SCCP (Skinny Client Control Protocol) is used for phone registration and media negotiation with CUCM, not for CTI desktop control commands from an application.
