Zoom rooms can be enabled with the phone feature without the need to physically call the room.

There are two options:

  • Zoom Room Callout or Outgoing Calls Only
  • Zoom room  as a SIP phone client for incoming and outgoing calls using internal PBX systems such as Cisco’s CUCM, Avaya, Shoretel, RingCentral.

You can dial another phone user with a 1: 1 phone or call the conference bridge at a non-Zoom meeting.
