Room Connector Call-Out for Zoom (replacing Jabber)

This article applies to: Zoom


If you previously used Jabber (which is being discontinued at Cornell) for video conferencing, you should switch to using Zoom's Room Connector features. 

If you are connecting to Zoom through your computer, you do not need this information. This method uses a/v equipment installed in some meeting spaces.

Start Room Connector Call-Out

  1. Start a Zoom meeting.
  2. Select Invite on the Zoom toolbar.
  3. Select Invite a Room System.
  4. Select the Call Out tab.
  5. Enter the IP address or SIP URI of the H.323 or SIP device, or select a device from the H.323/SIP Rooms Directory.
  6. Select the type of call you would wish to make - H.323 or SIP.
  7. Press Call.

Setting the Call Speed for Call-Out to H.323 Devices

The default call-out speed is 1920kbps (maximum). To set the call speed when using the Zoom call-out feature, you can enter the speed in to the dial string as seen in the three examples below.

[IP address];speed=768k

[IP address];speed=768000

[IP address]##[E.164 address];speed=1472k

Sending DTMF Tones in Call-Out to H.323 Devices

To send DTMF tones when connecting to a Gatekeeper, MCU, or other H.323/SIP hardware that requires a party number, conference number, or e.164 address, you can enter these in the Call-out dial string.

[IP address];dtmf=[DTMF tones]

  • DTMF tones have a 1 second interval.
  • Entering a comma will pause 1 second in between DTMF tones.

Here's an example:

Dial: 162.255.36.11;dtmf=15562#,,622#

This will dial IP address,
then send DTMF tones '1' '5' '5' '6' '2' '#'
pause pause '6' '2' '2' '#'

Device IP address: 162.255.36.11
Conference Number: 15562
Password: 622

To add a call speed along with DTMF tones (using the example above and a desired call speed of 768 kbps):

Dial: 162.255.36.11;dtmf=15562#,,622#;speed=768k
