Room Connector Call-Out for Zoom (replacing Jabber)
If you previously used Jabber (which is being discontinued at Cornell) for video conferencing, you should switch to using Zoom’s Room Connector features.
This article applies to: Zoom
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
- Start a Zoom meeting.
- Select Invite on the Zoom toolbar.
- Select Invite a Room System.
- Select the Call Out tab.
- 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.
- Select the type of call you would wish to make - H.323 or SIP.
- 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 into 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.
For example, a device’s IP address is 162.255.36.11, the conference number is 15562, and the password is 622.
The call-out dial string will be:
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’ ‘#’
To add a call speed along with DTMF tones append ;speed=[speed] to the end of the call-out. Using the example above, Dial: 162.255.36.11;dtmf=15562#,,622#;speed=768k will add a speed parameter of 768kb to the call-out string.
