Pickup BLF T38G

Hello,

I configure some memory key as a BLF key.
All works fine exept the pickup.

I configure a group pickup in the a programable key and it works fine.

Info of the phone:

• Firmware Version 38.70.0.221
• Hardware Version 21.4.5.160.64.0.0
  

Config of memory key:
BLF
value: 103 (its the extension)
Account: Account1 (its here is my extensions configured)

Account --> Advanced

Direct Call Pickup Code : *8
Group Call Pickup Code: *8


In the traces I can see that when I press the BLF pickup the phone, the phone adds at front of ext *8
But if I press only the group pickup, no.

This are the traces in both cases:

Could someone help me?
