I have a blackberry style. I am looking for an app that allows me to filter calls from certain numbers. I was hoping there is one that exists that would either cause the calling phone to return the busy signal or redirect the call to another number.
I have found iblockerpro which has a good review but it will only drop a call or sends it to voicemail. I understand this might be the only thing that is possible with an app, but thought I would double check.
Any help or suggestions would be greatly appreciated.
