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 below examples.

[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 "," will pause 1 second in between DTMF tones

For example:

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

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

  • Dials IP address 162.255.36.11
  • Send DTMF tones '1' '5' '5' '6' '2' '#' pause pause '6' '2' '2' '#'

To add a call speed along with DTMF tones (using the example above):

Desired Call-Speed: 768 kbps

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