Gigaset n510 IP Pro - Phone number after call pickup

[BSAEMS]

Hi all,

We've configured several n510's and those are working fine, but call pickup.
I've configured a ring-group and when this is called, I pick-up the ring-group with a Gigaset S650H .
For 1 second I see the outside calling number, but then the ring-groups name shows up.
Is it possible to get the outside calling number continuously showing in display?

Thanks,

John
