Lcr Table; Routing Of Outgoing Gsm Calls - 2N ISDN BRI GSM Enterprise User Manual

2N - ISDN BRI GSM Enterprise Gateway
If an outgoing call is routed via a port that is busy, the remaining
available ports are searched for (depending on the configuration)
and if no allowed outgoing port is free, the outgoing call
is rejected.
The routing algorithm routes outgoing calls according to the
outgoing call type, current time rate, day in a week, and GSM
provider's free minutes if any.

5.3. LCR table

The LCR (Least Cost Routing) chart is the key telephone cost
cutting factor. It helps you set the call routing rules according to
the CLIP, daytime and day in a week. By entering public holidays
into the LCR table you achieve even more remarkable cuts.
To make call routing to external ports based on prefixes and the
LCR table work properly, enter the GSM provider including its
respective code and prefix and the count of prefix-following digits
into the GSM destination table.
The ISDN GSM gateway also allows you to route outgoing GSM
calls on the basis of the SIM card position. In this case, outgoing
calls are not routed according to the GSM provider's number but
through the defined GSM module.
In addition, the ISDN ports can work in the pass-through mode.
This means that all calls are routed to the respective
complementary port without any check. Namely, from TE 1 to NT
1 and vice versa.

5.4. Routing of Outgoing GSM Calls

If the GSM gateway is connected to your PBX internal line, enable
the DISA function to the GSM network to make your GSM
gateway answer every call routed to it by the PBX and wait for
further dialling to GSM networks.
If necessary, this function can be restricted by defining a password
or selecting the CLIP.
Routing of outgoing calls via the ISDN BRI GSM gateway
proceeds as follows:
• The calling subscriber dials a number.
