Problems T28P+EXP38

[Mauro]

Now I attached a power connector to the third EXP.
But even minutes after I did that, I noticed that a few lights on the FIRST one did turn off for a while, and then returned on. I'll try to see what happens with a phone reboot later.

In the meawhile, we noticed another thing, maybe related to the firmware update performed. Now it is not possible anymore to use the buttons of the EXPs to pick up a call from a phone which is ringing.
E.g. if phone 221 is ringing, I see its light blinking on the EXP... pushing that BLF button while it's still ringing, I should be able to pick-up that call. But it does not happen anymore. The command to intercept a such call on the PBX is **number, in this case **221. Looking at the T28 display, it seems that touching the EXP button of the 221 number while it's blinking generates a **221221 instead of just **221.

Maybe with the new firmware, a different setting is required for that feature?
I checked in the "DDS keys" -> "EXT buttons" menu. The key is set as "BLF" with value "221", line "Line1" and Extension "**221".
To make a try, I tried to modify the "extension" field to just ** instead of **221, but after re-loading the page, that field automatically returns to **221.

Any ideas?
