hello all,

I have a question regarding MySQL licensing.

We configured kamailio to work in edge proxy mode with drive-by registration to support our network architecture. One of our clients is interested in conducting some trails with us and we are setting up a test network at client's facility. As a part of this process we will be installing our custom kamailio on their servers with MySQL. We are not charging our client for kamailio and mysql implementation since they both are open source implementations. But we will be charging them for our time at clients facility.

First, GPL license does not have any restrictions on charging. So, the question is not if you charge them or not. The question is: if you give them binary code, you have to give them (when they ask you) also the source code. Thus, if you have made changes to the code you have to give them also the changes.

Are we violating any MySQL license policies by installing our custom kamailio with MySQL for our client?

Mysql client libraries are by default GPL (unless you buy a comemrcial license). But as most of Kamailio is GPL too, I think you just have to obey the GPL license.
