You have several choices:

1. Use one of the SLT ports and program that extension to ring on all lines. That way, only a bell is required.

2. Program a relay contact to track the ringing, but you'll need to supply a power source and bell.

3. If there's an external paging system, you can program the lines to have UDA or UNA and a warble tone will be sent over the paging speakers when the lines ring.
