Asterisk and isdn TA adapter

I have a b410p card ISDN BRI, configured with 4 NT ports.
On one NT port(2) I connect a ISDN phone(is working), on the other(4) I connect a TA(usb hamlet) connected to a VM with Windows 2000 running(is without networking, so is safe) running a soft-phone isdn called rvs-com.
On the isdn phone I can make calls and receive calls. The isdn TA can receive calls(but fail the answer), but when I make a call from the TA…the asterisk console is totally mute, I also set the debug intense with the command

pri set debug on span 4

When I make a call with the soft-phone, give error isdn 3302, but seems it don’t connect to asterisk because as I said the console is mute.
What can be? I see the isdn ta put a international prefix before the call(+39), is this the problem? There is no way to remove this rule from Windows(as i know).
Those are my conf files

Continuation of B410p and isdn pbx, please help newbie

Solution found: was a misconfiguration of Libvirt: if I pass the usb TA isdn(usb redirect) the TA is recognized by the vm, but as I said the outgoing calls fail, the incoming calls make the “phone” ring, but at answer fail.
If I pass a pci-e usb adpter(need vfio/iommu) then I connect the usb Ta to the adapter works all fine.
The configuration files are little different and posted in this post
