| Description: |
Feature to generate DTMF tones during conversation. This feature is only available during connection.
Duration of DTMF tones:
- When parameter 1 = 0-11 the duration of the DTMF tone = RCO Pulse Time (default 3,5 seconds).
- When parameter 1 = 255 the DTMF tone is transmitted as long as the digit is pressed.
Examples:
 Digit 1 during conversation transmits DTMF #5 - Directory number 1 = feature 107/1: When digit 1 is pressed during conversation, DTMF digit 1 is transmitted (default for 3,5 seconds)
- Directory number 1 = feature 107/5: When digit 1 is pressed during conversation, DTMF digit 5 is transmitted (default for 3,5 seconds)
- Directory number 1 = feature 107/255: Dial digit 1 during conversation to enter "DTMF transmission mode". Audio from the conversation is now switched off. Successive digits will be sent as DTMF digits. E.g. 1 + 345 will send DTMF 3, then 4, then 5. The DTMF tone is transmitted as long as the digit is pressed. Press C-key to leave the "DTMF transmission mode" and return back to conversation mode.
Note that the conversation audio is switched off during DTMF tone transmission. <br\>
Feature 107/255 can not be followed by a 107/0-11 before the 107/255 DTMF-mode is terminated.
