Hi,
I have implemented voice call history plugin using memory mapped file ,
the implementation tested on meego images right now as an external
plugin to ofono. I am submitting the code here so that it works as
builtin plugin for ofono in future. Please review the patch and let
me know if your decision.
Thanks
