Fritzbox: get last caller

I have tried the Fritzbox binding 1.8.3. and 1.9.0 with OH1 and get the following error:

2017-03-04 11:36:06.692 [INFO ] [o.o.b.f.i.FritzboxTr064Binding] - Trying to resolve number 0411511009 to name comparing 7 characters

Irrespective of using CallType or StringListType.
Also, I cannot find any doc on StringListType…
… and why the event.log would update the items to # #
