Call Pickup and BLF while on call...

[dkpdesign]

Hello, I can't seem to understand one part of the blf function.

- While I am on a call, the main line (101) rings.
I put the call on hold
I then hit the blf key to answer the call (this works when answering the call when I am not on the phone)

When I hit the blf key, instead of answering the call, it calls extension 101. Why does it do that?

In order for me to answer the call, I have to put the current call on hold, then hit new call (or line 2), then hit the blf key.

I am using T26 phones.
