Hi everyone, Apologies for cross posting. I just wanted to announce that there is an alternative to OpenSMPPBox and commercial SMPPBox now available named KSMPPD - it is completely free under the same license as Kannel. It works with Kannel the same as the above to products just has some other differences detailed on the repository page.
If you would like to try it out in your deployments you can check it out here: https://github.com/kneodev/ksmppd If you have any issues or feedback you can leave them on the issue tracker. Thanks
