Using Zoom Phone with managed SIP/H.323 devices

A managed room system like Zoom Phone allows you to use a SIP/H.323 device as a conference phone in your room, instead of having to use a series of devices, and takes advantage of the microphone and speakers that are already in the room: making it easier for you to successfully hold meetings and to conduct presentations. In summary, this allows you to manage your rooms more effectively and efficiently while adding more functionality and options to the participants and users of your rooms.

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:

Zoom recommends using CE 9.9.2 or higher regardless of what firmware you are using.

Note about behavior change

In some cases, the 10-digit dialing behavior of a SIP/H323 room may change once it is configured with Zoom Phone. In order to make a call with Zoom Phone, you will need to dial a 10-digit number from the device keypad. Zoom Phone will recognize the number as a phone number and will attempt to contact it. Using a managed device that has a 10-digit number (for example, a tablet), the participant will need to add @zoomcrc.com (or whatever gateway their organization is using) before joining a Zoom meeting, for example, MeetingID@zoomcrc.com.

Known Limitations

• Zoom Phone does not support the OPUS codec.
• Please open a Zoom support case if you intend to join 3rd party meetings on WebEx via your provisioned SIP/H.323 rooms integrated with Zoom Phone. It is important to indicate the Calling Route Control (CRC) gateway your devices will be calling from, and the domain(s) you plan to call from (e.g. mydomain.webex.com). In order to make sure that these types of telephony calls from the room system will always be successful, we have implemented this measure.
• The room’s number can be assigned multiple numbers for inbound calls to the room, but the room’s primary number will be used for any outbound calls sent to the room.

How to set up a provisioned SIP/H.323 room with Zoom Phone

In the following steps, we will demonstrate how to configure the room system in Zoom so that Zoom Phone will be used in the room. To do so, select the room under the Cisco/Polycom Room tab during the process of assigning a Zoom Phone license.

In your profile, the Phone System Management section of the window will allow you to configure the room’s calling plan, phone number, and other settings after it has been assigned a Zoom Phone license.

How to use Zoom Phone with your room system

A ringing phone will appear on the touchpad and users will be able to answer the call on the display:

Using your device’s dial pad, enter the phone number you wish to call and then press the call button:

The main display will display the status of the connection, whether it is an incoming or an outgoing call:
