Question
The Partner would like further information on DTMF encoding and decoding capabilities in MOTOTRBO radios.
Answer
MOTOTRBO radios are capable of transmitting live dial DTMF tones. "Live dial" means that the radio user must press and hold the Push-To-Talk (PTT) button while entering the codes via the radio keypad. Since these radios only support live dialing, it is essential that the model includes a full keypad. The following radio models are supported:
* CP100d (full keypad model)
* XPR7550e - R7 (Display)
* XPR5550e with a full keypad microphone
* Make sure to use a supported model for DTMF functionality.
* Also see the guide on pages 1-46 (XPR5550E USER GUIDE)
