Are You sure this is a "feature" of the AVM controllers? I would
suspect, the connected PBX (or switch) looks at sender number, decides
that it does not fit into the allowed numbers and substitutes it with
the base number of the line.

Other PBXs may behave differently and reject a call with an invalid
sender number.
