Calls
Relax timeout [s] – time interval between the end of the last call and the
beginning of the next call via one and the same GSM module (all incoming and
outgoing calls are rejected during this timeout). The recommended value is 2
seconds. Do not change this setting unless absolutely necessary.

DTMF settings
The minimum delay between two identical DTMF characters received [s/100].
Tone detector settings
The GSM gateway can automatically detect user defined tones sent by the GSM/UMTS
network during call setup. In general, user defined tones are tones of the number to be
transmitted. Having detected such tone, the GSM gateway terminates the call
automatically and attempts to set it up through the next available outgoing group (as
defined in the LCR table).
Frequency 1;2;3;4 – defined frequency of the tone to be detected.
Sequence list – sequence of the above defined tones for detection.
Voice parameters of GSM modules
Here you can set the voice level for the GSM modules in the GSM gateway.
Audio level DSP

Caution
An excessively high volume may deteriorate the voice quality
(distortion, echo, etc.) and wrong DTMF detection!
