By any chance, do you know how to do forward call only from selected caller, e.g. 1-508-987-6543, to phone number 1-207-123-4567 on my T-Mobile Android phone? These two phone numbers are not real, just examples. Note, it is not general call forwarding, it is forwarding only from selected caller.
If you know how, please provide detailed instruction/link. If not, maybe you know name of the application to do it?
