If you are a resident of an Assisted Living facility, you need to contact your facility’s Hosted Phone for Seniors internal phone plan administrator with questions regarding your phone and it’s features. Your facility’s staff have been trained by EPB to handle any issues you may have. If you have trouble contacting your internal phone plan administrator, or need further assistance, you may call EPB at 423-648-1372 anytime day or night.

If a resident moves to another room, EPB can come out and relocate their number. If at any time you need to disconnect a resident's phone, just call EPB and we can remove the charge and plan to have the equipment returned. If you approve, a resident may take their Hosted Phone for Seniors number with them to another carrier or facility.
It depends on several factors. EPB creates a separate internet connection that is locked down for security reasons, so your phone service does share your business internet connection. If the on-premises internet connection has issues due to your equipment failure, the phones would continue to work. However, if an internet outage is an external issue, then phone service may cease to work until the outage is resolved. The root of the problem determines if any phone outage will occur. EPB is available 24/7/365 to take any trouble calls and dispatch a technician to your business, if needed.
EPB Hosted Senior Solution is a leased solution. The monthly lease amount pays for the dial-tone, maintenance of the hardware and ongoing support. The phones remain the property of EPB, but we will support the solution and replace defective handsets at no additional cost.
After you select a Hosted Phone for Seniors solution, an EPB Hosted Phone Coordinator will discuss the preferred training plan for your facility. This could simply include leave-behind support materials, or involve direct training at the individual level. Keep in mind that after training, EPB’s technical experts are available 24/7/365 to assist you via chat or by calling 423-648-1372.
