Communication Manager handles all the call operations in the no hold conference feature.

If you are on an active call, then using the no hold conference feature you can establish a conference call without interrupting the current conversation or putting the current caller on hold.

No hold conference feature works with or without a pre-configured destination.

If an endpoint is controlled by a CTI application then a feature key for Noholdconf is not required for that endpoint.

If you abort the no hold conference process the original call will remain active.
