How to send DTMF tones in a call-out to H.323 devices
DTMF tones can be sent by entering the party number, conference number, or e.164 address in the Callout dial string when connecting to hardware such as Gatekeepers, MCUs, or other H.323/SIP components that require a party number, conference number, or e.164 address for authentication.
DTMF = [DTMF tones];IP = [IP address]
- There is a 1 second interval between DTMF tones
- By entering a “,” in the middle of the DTMF tone, a pause of one second will be added
The following are some examples:
The IP address of the device is 162.255.36.11
The conference number is 15562.
The password is 622.
You can dial the following number: 162.255.36.11;dtmf=15562#,,622#
- The IP address that is dialed is 162.255.36.11
- The DTMF tones we send are ‘1’ ‘5’ ‘5’ ‘6’ ‘2’ ‘#’ pause pause ‘6’ ‘2’ ‘2’ ‘#’ DTMF tones we send are ‘1’ ‘5’ ‘5’
If you would like to add DTMF tones along with a call speed (using the example above):
I would like to have a call-speed of 768 kbps on my line
You can dial the following number: 162.255.36.11;dtmf=15562#,,622#;speed=768k
