7.2. Call Routing Rules
Calls from a VoIP port to a GSM network are routed according to
the LCR (Least Cost Routing) table to an arbitrary GSM port. 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.
Incoming calls from a GSM network are routed directly to the
defined SIP address, or the DISA function is enabled. The CLIP
function can be used too.
7.3. LCR table
The LCR (Least Cost Routing) table 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, define the prefix and the total count of
digits to be dialled into GSM in the Network list. The SIM card
inserted in the GSM gateway must be compatible with the defined
