3300 ISS Server 4.2
These is an option in COS:
Select "Yes" to display calling line identification on multicall and keyline appearances of directory numbers for SUPERSET display telephones. Select "No" and no information is displayed.
I would think from what I'm reading here is if you enable this, when a non-prime key rings it will replace the label with the caller ID.
Here's the scenario:
2 5330 sets.
ext 1111 has a the other 2222 as a button on his phone.
Call 2222 and the line rings on 1111 but the label doesn't change.
If the 2 phones are 5340 sets then it does changes but you can't turn it off via COS.
Any ideas on this?
