Compatibility : kannel version 1.4.3 or greater
Replace $nexmo_user and $nexmo_password in the example kannel.conf file linked below with your existing Nexmo SMPP credentials and restart your Kannel.
Note: The default API secret is 16 characters, so you will need to change this to 8 so that you can use it with Kannel. You can change the API secret in Dashboard, under Settings.
You are now ready to send a test message from your local Kannel server !!!
Remark : For security reason , the Kannel conf only allow access from localhost . In order to allow a new machine IP please add edit the following configuration lines.
Example with 2 IP X.X.X.X and Y.Y.Y.Y:
admin-allow-ip = "127.0.0.1;X.X.X.X;Y.Y.Y.Y"
box-allow-ip = "127.0.0.1;X.X.X.X;Y.Y.Y.Y"
user-allow-ip = "127.0.0.1;X.X.X.X;Y.Y.Y.Y"
