Using an ATA device to PAGE via legacy paging hardware

Hi @HowieMendoza 

Zoom Phone has some certified hardware for this.

On other systems, I have certainly used ATAs with auto-answer and analog audio out to link to a paging system.

I don't know if you can get raw SIP credentials for Zoom Phone though (maybe you can). If you can, I guess this would work. It might be unsupported on an unsupported device though.  You also might need some back-end permissions.

A purpose-built paging interface does make things easier though.
