Refer to the exhibit. The Base group that is configured in the TMS Provisioning Extension service of the Cisco Video Communication Server Identifies this VCS with the TMS Provisioning. Who assigns…

Cisco Unified Communications Manager manages voice call routing and telephony devices but has no role in assigning TMS provisioning group identifiers to a VCS.

The VCS does not self-assign the Base group value; it receives and uses the identifier that TMS provides during provisioning configuration.

Cisco TelePresence Conductor manages conference resource allocation and bridges but does not assign provisioning group identifiers used in TMSPE.

TMS is the central management and provisioning authority in the Cisco video collaboration architecture. When configuring the TMS Provisioning Extension (TMSPE) service on VCS, TMS generates and assigns the Base group identifier so it can uniquely associate the VCS with the correct provisioning domain. This value originates in TMS and is then entered into the VCS configuration, not the reverse.
