Hi
Im having some problems with Interoute´s siptrunking service after I`we applied CU2 on my servers.
It might be my configuration or it might be something at the other end (which I think it is)

So after some great help from some people from the mediation server team we found that
The FROM header in the 200OK responses to OPTIONS is wrong.
This is what Mediation Server sends:

This is the answer:

That’s why Mediation Server discards the answers from the other end.
