Calls

Relax timeout [s] – set the timeout between the end of the last call and
beginning of the next call made via one and the same GSM module (incoming
and outgoing calls are rejected during this timeout). The recommended relax
value is 2 seconds – please 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.

Holiday List

List of days on which calls will be routed like on weekends in the LCR.

DTMF Settings

Minimum delay between two identical DTMF characters [s/100] received.

Tone Detector Settings

The GSM gateway can automatically detect user defined tones transmitted by
GSM/UMTS for setting up outgoing calls to the GSM/UMTS networks. In general, they
are tones of a transferred number. For the purpose of such detection, the GSM
gateway automatically terminates the call and tries to set it up via another available
outgoing group (if defined in the LCR).

Frequency 1;2;3;4 – define the frequencies for the tone to be detected.
Sequence list – set the sequence of the tones to be detected.

Voice Parameters of GSM Modules

Set the voice level in the gateway GSM modules.

Audio Level DSP

Set the voice level for calls in the gateway signal processor.

Caution

An extremely high voice level may lead to poor voice quality
(distortion, echo, etc.) and wrong DTMF detection!

Tone Generated for Incoming calls from GSM/UMTS

Dial tone – set the dial tone for incoming calls from GSM/UMTS.
Ring tone – set the ring tone for incoming calls from GSM/UMTS.
Generate busy tone to GSM/UMTS – enable busy tone generation for call
termination.
