T23G - Setup to view incoming calls of other extensions

[apant]

Hello. Is there any kind of asterisk or yealink phone configuration to view incoming call notification (caller id) of other extensions on my phone?

Thank you.

To be more specific I want to monitor the caller ID of another extension as if I had configured a BLF and enabled the "Visual Alert for BLF Pickup" option. I want to do this because T23G has no many DSS Keys and I want to give members of the same pickup group the ability to view the caller id before pressing *8.
