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

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.

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:

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
