Call Routing 3.3

Routing Algorithm for Incoming Calls
Incoming calls are processed according to the Mode parameter setting in the GSM
incoming groups table. The following options are available:
 Reject/ Ignore incoming calls – incoming calls are not routed to the VoIP
network. On the GSM side, the connection request is either rejected or
ignored (the caller hears the check ringing tone).
 If the above mentioned option is not selected, the CLIP routing table is
checked. If the calling number is found, it is checked for CallBack first. If the
CallBack function is enabled for this number, 2N
® VoiceBlue Next will ignore
the incoming call and set up a CallBack to GSM after the caller hangs up. If
the AutoDial function is enabled for the calling number, the caller will be
routed directly to the extension number entered in the AutoDial item. If both
the CallBack and AutoDial functions are activated, 2N
® VoiceBlue Next will
ignore the incoming call and set up a call to GSM after the caller hangs up.
Simultaneously, a call to the VoIP extension will be set up and then the calls
will be connected. If the CallBack function is enabled and the caller fails to
hang up within 10 s, 2N
® VoiceBlue Next will try to set up a call according to
the AutoDial settings.
 In case the CLIP routing function is disabled or the calling number is not
included in the CLIP routing table, the Dynamic CLIP routing table is checked.
If the calling number is found, the incoming call is routed directly to the
corresponding extension. To set the Dynamic CLIP routing function use the
GSM incoming groups menu.
 If the incoming call is still not processed, the gateway will receive the call and
send either a voice message or the dialtone to the caller. After that, 2N
®
VoiceBlue Next awaits the required count of digits necessary for connection
set-up. Set the minimum and maximum counts of DTMF digits in the GSM
incoming groups menu.
 If 2N ® VoiceBlue Next does not receive the minimum count of digits and no
other digit comes within the timeout set in the DTMF dialling timeout
parameter, the call is forwarded to the operator as if the called extension
number were unknown.
 If call forwarding to the operator is inactive, the incoming call will be rejected.
