I'm looking for a way to ring an external ringer simultaneously with multiple IP phones. Currently these phones configured with overlay of all instances of extension 9944. I don't think the customer would accept ringing the ringer and then CFNA to phones or any other linear/sequential setup.
As I see it using a hunt group will not help since they can only be sequential, peer, or longest-idle. My customer didn't accept any of these setups I've done for them so I resorted to overlaying multiple instances of the main number to the IP phones. This was acceptable but now the external ringer has been introduced to the equation.
I don't yet know if I'll be using an FXS card or an ATA for the ringer. Most likely it will be an FXS card though.
We have have multiple sites with ATAs that interface to either a relay that triggers an existing bell or ringer or to a Wheelock ringer/strobe. These work pretty well and are are cheap and easy to install/setup. We have the ATA run off the 7940 switchport and then wired out to the ringer device.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
