We're building a new house in a Rural area and want to eliminate the landline.
This house is two story ADA with a small elevator. The elevator requires an emergency phone.
We also will have an OmniPro II system that needs a phone line.
The AT&T 4G LTE signal is strong in the area (we plan to use that for internet too).
I could install separate communicators for the OPII and elevator but that seems unnecessarily expensive and more to maintain.
Is there a product that will connect to the AT&T network to provide a dial tone that will work with both the elevator and alarm system?
How would you folks approach this problem?
