For a call setup, the LCR table is searched sequentially from top to bottom. Each LCR
table row is assigned a
in which the prefix match is searched for. If a match Prefixlist
is found, the call will be routed according to the routing group parameters ( in Groups
the LCR table) as set in the table. Gateway configuration GSM outgoing groups /
The call will be connected via the GSM module as assigned to the GSM outgoing

If the selected GSM/UMTS module is busy, the call is routed according to the next

The LCR row is checked in this way until a free GSM/UMTS module is found. If no

Routing Algorithm for Outgoing Calls
The GSM/UMTS outgoing call routing algorithm is launched whenever the SIP Proxy
routes an outgoing call to
. Outgoing calls are routed via 2N VoiceBlue Next

as follows: VoiceBlue Next
The calling subscriber dials the subscriber number and the SIP Proxy routes it to

The number prefix is checked against the prefixes in the tables List of networks
in the ascending sequence, i.e. table 1 is searched first, followed by table 2 and
so on.
When a matching prefix is found in a
, the LCR is checked for a List of networks
valid row. Again, the LCR is searched upwardly, starting from the first row.
If a
number matches a valid number on the respective row, List of networks
the call time is checked against the routing rule. If no match is found, the next
LCR row is checked.
If the
number and call time meet the routing rules, the call is List of networks
routed to the module selected in the table Assignment to GSM groups
according to the first routing rule included in the section and given in the Groups
table. GSM outgoing groups
Moreover, call duration limiting timer can be selected for the outgoing call.
If the selected GSM/UMTS module is occupied or has a low credit, the algorithm
returns to the preceding step but considers the next
row instead of the Groups
first one. If no record is found in this section, the next LCR row is used.
Poznámka
Count of digits defines the minimum count of digits to be dialled. Hence,
a call is successful if the count of the called number digits is equal to or
higher than the value set in the
