Question

Which Cisco Unified Communications Manager protocol communicates with collaboration endpoints?

Options

ASCCP
BRTP
CSIP
DCDP

Explanation

SIP is the open, standards-based signaling protocol that Cisco Unified Communications Manager uses to communicate with modern collaboration endpoints.

Common mistakes.

A. SCCP (Skinny Client Control Protocol) is a legacy Cisco-proprietary protocol used with older IP phones that is being deprecated in favor of SIP and does not represent the current standard for CUCM collaboration endpoint communication.
B. RTP (Real-time Transport Protocol) carries the voice and video media stream between endpoints after a call is established but is not a signaling or registration protocol managed by CUCM for endpoint communication.
D. CDP (Cisco Discovery Protocol) operates at Layer 2 to discover neighboring Cisco devices and exchange information such as VLAN IDs, performing no call signaling or endpoint registration function within CUCM.

Concept tested. SIP as CUCM standard collaboration endpoint protocol
