In TMS, an externally hosted conference is a conference that has been created outside of your Cisco TMS. You can schedule endpoints in your organization to pin this conference by booking Externally…

MCUs cannot be assigned to Externally Hosted Conferences because the conference is bridged externally and TMS cannot allocate internal MCU resources to an outside-hosted session.

Non-SIP dial-in participants are not supported for Externally Hosted Conferences, as this conference type requires SIP-based connectivity to reach the external host.

Automatic Connect is a supported dial-in type for Externally Hosted Conferences, allowing endpoints to automatically connect to the external conference bridge without requiring manual dialing by participants.

Recording participants can be added to an Externally Hosted Conference booking in TMS, enabling session capture even though the conference bridge itself is managed outside of TMS.

One-Button-To-Push (OBTP) is not available for Externally Hosted Conferences because OBTP relies on TMS internally managing and pushing conference details to endpoints, which is incompatible with external hosting.
