I'm at a loss to explain the reported behaviour. When user A called user B at one extension, says extension 2523. and that extension has been setup by User B to automatically transfer call to his mobile phone (PSTN) when he doesn't pick up the office phone. Now strange thing happen, the moment user B pick up his mobile, his mobile phone number gets display at User A IP Phone screen, show "From XXXXXXXX". XXXXXXXX is the User B's mobile phone number.
Please note here, display "From XXXXXXXX"! I have tested on any phone extension that have been setup transfer to a mobile phone, that mobile phone number get display at the screen. Means what? Now User know other's mobile phone number even though he really don't know it in advance!
I am using callmanager4.1(3)sr56, IP phone is cisco 7960. Voice GW is 3825, IOS version is "c3825-spservicesk9-mz.124-15.T1.bin"
Has anyone seen anything similar, as I can't even think of a series of events which might explain this.
