[IP address];speed=768kHow to send DTMF tones in a call-out to H.323 devices
You can enter the party number, conference number, or e.164 address in the Call-out dial string when connecting to a Gatekeeper, MCU, or other H.323/SIP hardware that requires these.
- 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
