1) This is a support question, not a "general discussion". (I've moved the topic to Support accordingly
)
2) I'm sorry, I don't know what a "trunk OVH" is. Not a clue
3) Please post your system specs EVERY time you post, similar to this:
Vicibox X.X from .iso | Vicidial X.X.X-XXX Build XXXXXX-XXXX | Asterisk X.X.X | Single Server | No Digium/Sangoma Hardware | No Extra Software After Installation
4) AT LEAST post your Vicidial Version with Build and also your Installation Method (name of the .iso image).
5) How did you "activate" the AMD function? What settings did you use, and where?
