[OpenSIPS-Users] Diameter

[Ghaith ALKAYYEM]

Actually, openblox project has two versions, one is proposed as a
commercial and the other as an open license version.
It's implemented in JAVA and they mentioned in their web site that
there's a C++ implementation but I couldn't reach it through their web
site.
you can see the product in the following link:
