Thank you for that information.
If I am reading correctly, assuming an office scenario where all call handlers are withing 20 feet of each other, If a call comes in and extension 10 answers the call. The calling party then asks to speak to the call handler on extension 15. Extension 10 places the call on hold and then tells extension 15 to pick up the call, which extension 15 does. Then the SMDR report would show extension 10. I am assuming this as the call was not actually transferred or forwarded and coverage and pickup groups are not assigned.
