Why each option
Cisco TMS prioritizes H.323 over other protocols when initiating and managing conferencing connections.
SIP is supported by Cisco TMS but is not the prioritized protocol - H.323 takes precedence in TMS dial logic and call setup sequencing.
MGCP is a media gateway control protocol used for PSTN gateway signaling, not a conferencing protocol managed or prioritized by TMS.
Cisco TMS was architected around H.323 as the primary conferencing protocol because the Cisco TelePresence ecosystem was built on H.323 infrastructure before SIP became prevalent, and TMS defaults to H.323 when an endpoint supports multiple protocols for backward compatibility and feature completeness.
SCCP is a Cisco proprietary signaling protocol for IP phones registered to CUCM and is not used as a conferencing protocol in TMS.
