Using Zoom Phone with managed SIP/H.323 devices Follow

Integrating Zoom Phone with your managed room system, allows the flexibility to utilize your SIP/H.323 device as a conference phone, reducing the number of devices in your conference room, and utilizing the microphone and speakers built into your room. This allows you to manage your rooms more efficiently and effectively while expanding the capability and options for your rooms’ users and participants. 

Features available with the Zoom Phone and Managed SIP/H.323 integration:

  • Inbound and outbound calling through Direct Inward Dial (DID)
  • Inbound and outbound calling with external numbers
  • Inbound call forwarding to a Conference Room Connector device
  • Outbound emergency calling
  • Inbound and outbound international calling
  • DTMF tone compatibility with IVR systems
  • Miscellaneous Call Features where applicable (mute/unmute, hold/resume, call forwarding straight to designated voicemail, etc.)

Note about behavior change

Once a SIP/H323 room has been set up with Zoom Phone, 10-digit dialing behavior may change. Dialing a 10-digit number from the device keypad will be recognized as a phone number and Zoom Phone will try to make a call to that number. To join a zoom meeting from a managed device using a 10-digit number, the end-user will need to include @zoomcrc.com (or the appropriate gateway used by their organization), for example, "meetingID@zoomcrc.com".

Known Limitations

  • The OPUS codec is not a supported audio codec when using Zoom Phone.
  • Using your provisioned SIP/H.323 room with Zoom Phone and 3rd party meeting invites (WebEx, etc.) In order to continue to use your CRC device to dial into 3rd party meetings, please open a Zoom support ticket indicating the CRC gateway your devices will be calling from, and the domains you intend to call into (e.g. mydomain.webex.com).
  • While multiple numbers can be assigned to a room for inbound calls to the room, any outbound calls will use the primary number assigned to the room.

Setting up a provisioned SIP/H.323 room with Zoom Phone

Once your room system has been provisioned in Zoom, the room can be configured to utilize Zoom Phone, by selecting the room under the Cisco/Polycom Rooms tab when assigning a Zoom Phone license. 

After the room has been assigned a Zoom Phone license, the room's calling plan, numbers, and other settings can be configured from within the Phone System Management section of your profile.
