Least cost routing
This is a configuration example on how to setup least cost routing in
Ozeki NG SMS Gateway. Least cost routing means, that SMS messages are
routed to the appropriate SMS service provider connection based on
the telephone number prefix.
In our example, there are four SMS Service provider connections: MTN,
T-Mobile, Orange, Vodafone. The routing is setup the following way:
- If an SMS is sent to a phone number that starts with +3670 it should be
routed to MTN
- If an SMS is sent to a phone number that starts with +3630 it should be
routed to T-Mobile
- If an SMS is sent to a phone number that starts with +3620 it should be
routed to Orange
- All other SMS messages should be routed to Vodafone
To setup this routing the outbound routing table should be modified. The
outbound
routing table, that determines which service provider connection will
be used to send an SMS message, can be found in the bottom part of the
center panel of the management form of Ozeki NG (Figure 1).

To configure the desired routing, the routing table must have four entries.
The first 3 entries should have a regular expression condition to match a
telephone number
prefix. The last entry should have a condition that matches all SMS messages
(Figure 2).
