Hi to all

i see here many posts for this issue but i didnt find anywhere a clearly answer so i decided to open a new document

Here we have to PRIS

On controller 0/0/0 incoming and outgoing are fine

On controller 0/1/0 outgoing is ok but incoming has problem(not some calls but all the calls)

Note::

((((when you call to a number you hear a busy tone , but the called person see on his phone 2 missed calls))))

Below is the debug for a fail call
