Unify OpenScape CP400 User Manual

Making calls 89
Carry out DMTF-suffix/dial tone
In order to control devices, such as answering machines or automatic informa-
tion systems, you can send out DTMF signals (Dual Tone Multi-Frequency).
Please ask your administrator to send the codes for the DTMF tones.
Ending the call also deactivates DTMF suffix dialing.
Your system can also be configured in such a way that you can start the
DTMF dial-up immediately after establishing the connection. You can also
set-up a key for DTMF dialing.
