Keypad DTMF is only useable on Full Keypad models of the portable radios, as it utilizes all of the buttons.
If the end user is needing a programmable list of DTMF tones, there is a feature addition already in place for this that I could link this ticket to.
Currently, Pre or Post Tx ANI with a custom DTMF tone would be the only way the user would be able to send out a DTMF tone with a call. To get multiple different tones, they could create copies of their conventional system each with unique tones to mimic this behavior.
Have this end user directly reach out to tech support with their programming if they are having issues or questions regarding operations of their radios.
