Controlling devices with dual-tone multifrequency signalling (DTMF)

Your telephone must be set to dual-tone multifrequency

signalling (DTMF) for certain connections, for example, if

you want to check an answering machine or a voice in-

fobox or avail of telecom services such as CityRuf or Scall

(paging services available in Germany).

If your Gigaset 2011 is connected to a line with DTMF sig-

nalling, every connection is automatically set up using

DTMF signalling mode. If this is the case, you do need the

function to switch to DTMF signalling.

If the device is connected to a line with dial pulsing (DP),

you can switch to DTMF signalling once the connection

has been set up.

You can check which signalling method is set if you are un-

sure (➔ page 13). DTMF signalling is set by default.

Prerequisite: an external connection exists.

Once you have switched to DTMF, you can

switch between the two signalling methods

during the connection using the

recall key.

When the line is disconnected, the telephone

will automatically return to the original signalling

method.
Any digits or symbols that you enter after

switching signalling methods are not copied to

the redial memory.
