Show "called line" on phone?

[Voodoopupp]

Hi,

thanks for your feedback.

I am unsure, if we do understand each other correctly

We do have a SIP Trunk which is managed in the PBX, in my Example Bob has the extension "12"

But Bob is just a part of the Team 85, where all these people are in:
Name - Extension
Bob - 12
Jane - 13
Ron - 14
Andy - 15
Tina - 16

Now ALL of these extensions should ring linear, when someone is calling these external numbers:
XXXXXX-10 -> Sales Department
XXXXXX-20 -> Marketing
XXXXXX-30 -> Customer Service
XXXXXX-40 -> IT Service

Means: firstly Bobs phone is ringing, if he does not answer or is already talking, Janes phone rings and so on.

But sometimes they are not at their desks, so everybody should be able to logout/login of the Team with "one click".
Also it is not possible to configure external lines to the different phones! The PBX can only map one external number to one phone!
Therefore wen need to use teams/groups, so a team can manage multiple numbers.

And for the question if our PBX can pass the needed information to the phone in general: YES, this is possible!
here is a screenshot of a different phone, which could handle it the way I want.
But this is an old model, which is no longer produced and still uses ISDN (we only can handle IP Phones).
   

So here the phone can show the called external line "Sales" and the extention.

Hope, this is possible with the Yealinks in any kind of way!?
