Least Cost Routing (LCR) - SMS routing

This is a configuration example on how to setup least cost SMS routing in Ozeki SMS Gateway.

What is least cost SMS routing?

Least cost SMS routing means, that SMS messages are routed to the appropriate SMS service provider connection based on the telephone number prefix. If you are not familiar with SMS routing at all, we recommend you to read the SMS routing basics guide before you continue.

How to setup least cost SMS routing (Easy guidelines)

To setup least cost SMS routing:

  1. Read the SMS routing basics guide if you need
  2. Add new route on the outbound routing table in Ozeki
  3. Specify the message route on Route details' Settings tab
  4. Enter phone number prefix on Match menu's To address tab
  5. Select the appropriate prefix matches SMS Service provider
  6. Repeat these steps with every service provider connection
  7. Return to main page where now the routing rules appeared

In our example, there are three SMS Service provider connections: Telenor, T-Mobile, Vodafone. The routing is setup the following way:

  • If an SMS is sent to a phone number that starts with +3620 it should be routed to Telenor
  • 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 +3670 it should be routed to Vodafone
  • All other SMS messages should be routed to one of these providers randomly.

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 centre panel of the management form of Ozeki SMS Gateway (Figure 1).
