| Your tech is technically correct. If you have more than the number of lines than the DKT2020 can display, any CO lines not shown, is difficult to access, esp if someone puts it on hold.
However, to overcome this, you can add a DADM to each phone but do look up in the General Decription on how many your DK280 can support.
Or, you can separate/group each CO line for each extension if possible.
I would not suggest a pooled-key solution either. |
