Voice parameters of GSM modules
Here you can set the voice level for the GSM modules in the GSM gateway.
Audio level DSP
Here you can set the voice level for calls in the signal processor of the GSM
gateway.

 An excessively high volume may deteriorate the voice quality (distortion,
echo, etc.) and wrong DTMF detection!
Tone generated for incoming calls from GSM/UMTS
 Dialtone - the dialtone type for GSM/UMTS incoming calls.
 Ring tone - the ringing tone type for GSM/UMTS incoming calls.
 Generate busy tone to GSM/UMTS - generation of the busy tone for call end.

calls billed by the GSM/UMTS operator increases!
Error GSM/UMTS causes

call that meets the below mentioned requirements will be rejected with a
user-defined cause (the ISDN cause number will be transformed into a SIP
code for VoIP according to the table shown below).
o Lack of digits in OVERLAP mode – the call will be rejected that fails to
meet the minimum digits requirement.
o Restricted number prefix – the call will be rejected whose prefix has not
been found in any of the prefix lists.
o Selected module / GSM group is not ready – the call will be rejected in
case no GSM module is available in the LCR-selected GSM outgoing
group.
o Selected module / GSM groups are not ready – the call will be rejected
in case no GSM module is available in the LCR-selected GSM outgoing
groups.
Cause translation
Here you can convert the release cause received from GSM/UMTS into another
ISDN release cause. The resultant ISN cause number will be transformed into a VoIP
SIP code as included in the table below:
