I can not make outbound call trow my VSP line busy?

[capron]

I am new too voxalot and like it alot. Still I have big problems

My outbound calls throw my VSP dont work only get line busy.
The dialplan shows my that the outbound shud be roueted throw
my VSP so this is correct. I can also dial the voxalot echo test.

I belive that there is a problems too connection
between voxalot and my VSP is there a way too debug this?

My provider is in sweden proxy.digisip.net
And I dont know what I shud write in the From Domain ?
