Hello Geert,
i just wanted to correct a small thing:
/Running 2 instances of ser isn't necessary, but I have it working like that, because I don't want to run a CVS version of SER for call routing, but I want to run a CVS SER & SEMS for voicemail because the CVS version has more functionality and the SEMS CVS version is not compatibel with the stable SER version (0.8.12).
The last CVS version of Sems IS compatible with Ser 0.8.12. In a way to avoid breaking compatibility with future developement, i just created a new branch: ser_rel_0_8_12. This branch will stay compatible with Ser 0.8.12. So, you don't need to run unstable version of Ser if you don't want to.
