I have never heard of a way to automatically add digits when using PRI,
however can you check your chan_dahdi.conf about the following lines:

internationalprefix =
nationalprefix =
localprefix =

If presents, try messing with them. If you are using the PRI in Italy,
every provider has PRI configured in its own way, some time even the same
provider is configuring PRI lines in multiple times, but often the problems
are on receiving the calls (like calls with and without the area code, with
or without the leading zero, etc. etc.)
