further digits dialled from VoIP to GSM.


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.

Timeout for ringing to GSM [s]

– ringing timeout for outgoing calls to GSM. If not

answered or terminated within this timeout, the call will be terminated
automatically by the gateway when this timeout elapses.

Bank holiday list

A list of dates to which the weekend routing mode should be applied in the LCR table.

DTMF settings

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.
