End-to-End DTMF Signaling (Tone Through)
Description
DTMF (Dual Tone Multi-Frequency) signaling is required for access to special network
services offered by some telephone companies. This system allows the proprietary telephone
user to send DTMF signals to the line during an established call.
Conditions
• If the dial type of the line is assigned to DTMF, Tone Through mode is established
automatically after the dialling sequence is finished and the call is established.
• If the dial type of the line is assigned to dial pulse, Tone Through mode is established after
the dialling sequence is finished and the " #" buttons are pressed (Pulse to Tone
Conversion).
• This function also applies to extension and conference calls.
