APX RADIO -- DTMF DECODE ON P25 / PHONE MENU

[52ahuffman]

Hello,
Forewarn I am going down a rabbit hole;

I am attempting to get a APX portable to decode / call alert DTMF tones on a P25 Phase II talk group. Phone Menu Item "Denied" when attempting to transmit DTMF tones.

Long drawn-out explanation: A fire dispatch agency using DTMF tones to alert fire calls (555555) and (656565) and I am attempting to get the radio to call alert when they tone out. I have added the "Phone Number" to the call list. I have also enabled the "Phone" Option in the menu options and have selected "Unlimited" in the Trunked Personality. When attempting to transmit the DTMF tones automatically from the portable I get a "Denied"

Thank you, Any help appreciated!

Chances are they’re utilizing P25 Digital Tone Signaling, and if so you’d have to set that up accordingly within the codeplug, granted your radio is properly optioned to do so

OP explains that they do DTMF tones over P25.. unless you mean, attempt to do tone signaling to trick based off of the Hz.
