Do you know how to identify diverted calls?

Hi

First time poster here. Can anyone tell me if there is a way of knowing which calls have diverted from my office number and which are made directly to my Blackberry 9700? Is there an app or a setting that will show which calls are diverted calls and which aren't?

I often set a call divert on my office landline to my 9700, but I can't tell which calls were originally made to my office number and which were made direct to my BB. I'd like to know whether the people calling are expecting that I'm at my desk or if they understand that I might be out and about. Is there any way of doing this? Thanks a million.

It usually says "Diverted Call" as soon as your phone rings. Bad news is that it says that only for 2 secs
