Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
There is not an external amplifier available from panasonic directly.I can recommend an alternative amplified phone system, if you want to return this system.
OR, I can recommend an external (aftermarket) ringer/amplifier, but keep in mind that will ONLY work on the main base station, so you'd only hear it ring in the main room, not where any of the cordless handsets are located.
Which would you prefer, and which is the current model you have?
