group. To assign a group to outgoing and incoming calls use the
GSM groups assignment table.
During call establishing, the LCR table is checked line by line
from top to bottom. If the called destination prefix matches the
network prefix included in the Network list (called Network ID in
the LCR table), the call is routed according to the routing group
(Groups in the LCR table) as set in GSM outgoing groups. The call
is connected via the GSM module assigned to the GSM outgoing
group in the GSM groups assignment table.
If the selected GSM module is busy, another routing rule included
in the Groups menu and defined by GSM outgoing groups is used.
Again, an outgoing GSM group is assigned to the GSM module in
the GSM groups assignment table.
The LCR line is processed in the above-mentioned way until a free
GSM module is found. If no suitable GSM module is found (GSM
outgoing group), the call is rejected.
7.4. Call Routing to GSM via VoiceBlue Lite
The outgoing GSM call routing algorithm starts the moment the
SIP Proxy routes an outgoing call to VoiceBlue Lite.
Outgoing calls are routed via VoiceBlue Lite as follows:
• The calling subscriber dials a number that is routed to
VoiceBlue Lite by the SIP Proxy. It depends on your SIP Proxy
configuration whether or not outgoing GSM calls are routed to
VoiceBlue Lite.
• The dialled prefix is first compared with the prefixes included
on the first line of the LCR table. If no match is found, the
following line is used for comparison.
• If the prefix matches a LCR prefix, the call time is checked for
match with the routing rule on the line. Again, if no match is
found, the following LCR table line is searched.
• In case the prefix and call time comply with the routing rules,
the call is routed according to the first routing rule included in
Groups and GSM outgoing groups to the module defined in
GSM groups assignment.
