• If the selected GSM module is busy or has an insufficient
credit, the preceding step is repeated for the following line of
the Groups section. If there is no record, the next LCR table
line is searched.
• In case the selected GSM module is free and has a sufficiently
high credit, the GSM gateway starts dialling the GSM number.
• If the calling subscriber number has an unknown prefix, or all
routes are busy, the GSM gateway rejects the call request.
• An outgoing call is not billed until the called party answers the
call.
• The GSM network signals the off-hook and the GSM gateway
transfers this information to the SIP Proxy.
• You can enable transmission of a connecting tone for
outgoing GSM calls, which replaces the silent moment
between the request sending and ringing tone.
