DTMF allows you to dialup and ring other sites using the 2-wire hand-
set. Only the ringing is detected. Communication over the handset is
party-line. DTMF addressing is a local function not a network func-
tion, therefore if one or more radios are assigned the same DTMF
address, they will all ring when that address is dialed.
To be able to use the DTMF function:
1. Audio 1 must be selected for 2-wire handset operation.
2. DTMF must be turned ON on the Audio provisioning screen.
3. 2-wire handset must be connected to TEL jack on controller module.
4. Radios must be provisioned with DTMF address.
