freitasm: Could you please tell us why you need the diversion to the mobile phone?
Why only at certain times?
This is actually a good question, if you can tell us exactly why this number and if you actually need going to a mobile or pehaps another land line obviously call forwarding to a local number has no cost as it's free local calling, we probably have a number of options based on what you need to do
For example, you can divert to land lines or Mobile, your choice,
You also don't have to have a "Device online" or connected and just use the service as a virtual mapping to the number of your choice.
We will also have a number of advanced features coming shortly where you can do time of day switching to numbers, and call forwarding based on Whos Calling etc, so if you can give us a bit more of a overview we can see how we can best assit.
